of the islanders. Therefore, this indicator will be divided into two sub-indicators:
a1. Natural tourism attractiveness a2. Cultural tourism attractiveness
b. Tourist capacity
The two island communes in Quan Lan have different capacities to receive tourists. Minh Chau Commune is home to many standard hotels and resorts, attracting high-income domestic and international tourists. Meanwhile, Quan Lan Commune has many motels mainly built and operated by local people, so the scale and quality are not high, and will be suitable for ordinary tourists such as students.
c. Time of exploitation of Quan Lan Island Commune:
Quan Lan tourism is seasonal due to weather and climate conditions and festivals only take place on certain days of the year, specifically in spring. In Quan Lan commune, the period from April to June and from September to November is considered the best time to visit Quan Lan because the cultural tourism activities are mainly associated with festivals taking place during this time.
Minh Chau island commune:
Tourism exploitation time is all year round, because this is a place with a number of tourist attractions with diverse ecosystems such as Bai Tu Long National Park Research Center, Tram forest, Turtle Laying Beach, so besides coming to the beach for tourism and vacation in the summer, Minh Chau will attract research groups to come for tourism combined with research at other times of the year.
d. Sustainability
The sustainability of ecotourism sites in Quan Lan and Minh Chau communes depends on the sensitivity of the ecosystems to climate changes.
landscape. In general, these tourist destinations have a fairly high level of sustainability, because they are natural ecosystems, planned and protected. However, if a large number of tourists gather at certain times, it can exceed the carrying capacity and affect the sustainability of the environment (polluted beaches, damaged trees, animals moving away from their habitats, etc.), then the sustainability of the above ecosystems (natural ecosystems, human ecosystems) will also be affected and become less sustainable.
e. Location and accessibility
Both island communes have ports to take tourists to visit from Van Don wharf:
- Quan Lan – Van Don traffic route:
Phuc Thinh – Viet Anh high-speed boat and Quang Minh high-speed boat, depart at 8am and 2pm from Van Don to Quan Lan, and at 7am and 1pm from Quan Lan to Van Don. There are also wooden boats departing at 7am and 1pm.
- Van Don - Minh Chau traffic route:
Chung Huong high-speed train, Minh Chau train, morning 7:30 and afternoon 13:30 from Van Don to Minh Chau, morning 6:30 and afternoon 13:00 from Minh Chau to Van Don.
f. Infrastructure
Despite receiving investment attention, the issue of infrastructure and technical facilities for tourism on Quan Lan Island is still an issue that needs to be resolved because it has a direct impact on the implementation of ecotourism activities. The minimum conditions for serving tourists such as accommodation, electricity, water, communication, especially medical services, and security work need to be given top priority. Ecotourism spots in Minh Chau commune are assessed to have better infrastructure and technical facilities for tourism because there are quite complete and synchronous conditions for serving tourists, meeting many needs of domestic and foreign tourists.
3.2.1.4. Determine assessment levels and assessment scales
Corresponding to the levels of each criterion, the index is the score of those levels in the order of 4, 3, 2, 1 decreasing according to the standard of each level: very attractive (4), attractive (3), average (2), less attractive (1).
3.2.1.5. Determining the coefficients of the criteria
For the assessment of DLST in the two communes of Quan Lan and Minh Chau islands, the students added evaluation coefficients to show the importance of the criteria and indicators as follows:
Coefficient 3 with criteria: Attractiveness, Exploitation time. These are the 2 most important criteria for attracting tourists to tourism in general and eco-tourism in particular, so they have the highest coefficient.
Coefficient 2 with criteria: Capacity, Infrastructure, Location and accessibility . Because the assessment area is an island commune of Van Don district, the above criteria are selected by the author with appropriate coefficients at the average level.
Coefficient 1 with criteria: Sustainability. Quan Lan has natural and human-made ecotourism sites, with high biodiversity and little impact from local human factors. Most of the ecotourism sites are still wild, so they are highly sustainable.
3.2.1.6. Results of DLST assessment on Quan Lan island

Basically, both Minh Chau and Quan Lan localities have quite favorable conditions for developing ecotourism. However, Quan Lan commune has more advantages to develop ecotourism in a humanistic direction, because this is an area with many famous historical relics such as Quan Lan Communal House, Quan Lan Pagoda, Temple worshiping the hero Tran Khanh Du, ... along with local festivals held annually such as the wind praying ceremony (March 15), Quan Lan festival (June 10-19); due to its location near the port and long exploitation time, the beaches in Quan Lan commune (especially Quan Lan beach) are no longer hygienic and clean to ensure the needs of tourists coming to relax and swim; this is also an area with many beautiful landscapes such as Got Beo wind pass, Ong Phong head, Voi Voi cave, but the ability to access these places is still very limited (dirt hill road, lots of gravel and rocks), especially during rainy and windy times; In addition, other natural resources such as mangrove forests and sea worms have not been really exploited for tourism purposes and ecotourism development. On the contrary, Minh Chau commune has more advantages in developing ecotourism in the direction of natural tourism, this is an area with diverse ecosystems such as at Rua De Beach, Bai Tu Long National Park Conservation Center...; Minh Chau beach is highly appreciated for its natural beauty and cleanliness, ranked in the top ten most beautiful beaches in Vietnam; Minh Chau commune is also home to Tram forest with a large area and a purity of up to 90%, suitable for building bridges through the forest (a very effective type of natural ecotourism currently applied by many countries) for tourists to sightsee, as well as for the purpose of studying and researching.

3.2.2. Using SWOT matrix to evaluate Quan Lan island tourism
General assessment of current tourism activities of Quan Lan island is shown through the following SWOT matrix:
Table 3.5: SWOT matrix evaluating tourism activities on Quan Lan island
Internal agent
Strengths- There is a lot of potential for tourism development, especially natural ecotourism and humanistic ecotourism.- The unskilled labor force is relatively abundant.- resource environmentunpolluted, still
Weaknesses- Poorly developed infrastructure, especially traffic routes to tourist destinations on the island.- The team of professional staff is still weak.- Tourism products in general
quite wild, originalintact
general and DLST in particularalone is monotonous.
External agents
Opportunity- Tourism is a key industry in the socio-economic development strategy of the province and Van Don economic zone.- Quan Lan was selected as a pilot area for eco-tourism development within the framework of the green growth project between Quang Ninh province and the Japanese organization JICA.- The flow of tourists and especially ecotourism in the world tends toincreasing
Challenge- Weather and climate change abnormally.- Competition in tourism products is increasingly fierce, especially with other localities in the province such as Ha Long, Mong Cai...- Awareness of tourists, especially domestic tourists, about ecotourism and nature conservation is not high.
Through summary analysis using SWOT matrix we see that:
To exploit strengths and take advantage of opportunities, it is necessary to:
- Diversify products and service types (build more tourism routes aimed at specific needs of tourists: experiential tourism immersed in nature, spiritual cultural tourism...)
- Effective exploitation of resources and differentiated products (natural resources and human resources)

Conditions on Political Security, Social Security and Tourism Development Policies
+ TNDLST is rich and diverse, including many unique resources with great appeal.
+ TNDLST is often very sensitive to impacts.

+ TNDLST has different exploitation time.
+ TNDLST is often located far from residential areas and is exploited on site to create SPDL.
+ TNDLST has the ability to regenerate and be used for a long time.
- Types of TNDLST:
+ Typical HST types and biodiversity:
▪ Tropical forest ecosystem: Tropical monsoon evergreen forest ecosystem (tropical humid forest ecosystem); Tropical monsoon evergreen forest ecosystem on limestone mountains,...
▪ High mountain ecosystem
▪ Wetland ecosystem: Coastal mangrove ecosystem; Inland swamp ecosystem
land; river and lake ecosystems; lagoon ecosystems;
▪ Coral and seagrass ecosystems.
▪ Coastal sand ecosystem.
▪ Sea and island ecosystems.
▪ Agricultural ecosystem.
These specific ecosystems are often concentrated in national parks and nature reserves. Therefore, the exploitation of ecotourism potential to serve tourism development is often associated with these areas.
+ Specific TNDLSTs: Garden, Bird Sanctuary, Natural Landscape. In which, natural landscape is the overall combination of natural components in which terrain, vegetation cover and rivers play an important role in creating attractive factors to attract tourists [11].
+ Indigenous cultural values: in each biological region (unit), ethnic minorities have also adapted - existed - developed associated with biological regions, creating indigenous cultural values typical of each biological region.
Indigenous cultural values often exploited as TNDLST include:
▪ Knowledge of cultivation, exploitation, conservation and use of biological species and serving the life of the community.
▪ Cultural activities with traditional festivals.
▪ Folk architecture, works associated with community legends.
▪ Handicraft products are closely associated with community life.
▪ Historical, cultural and archaeological relics are closely linked to the development history and beliefs of the community.
- TNDLST assessment:
There are many criteria to evaluate TNDLST such as: attractiveness, safety, sustainability, tourist capacity, connectivity, infrastructure and facilities - technology, etc.
+ Attractiveness: is the most important criterion to evaluate ecotourism because it determines the attraction of tourists. For ecotourism, the attractiveness of ecotourism is determined by the uniqueness of ecological values, biodiversity, landscape values and indigenous culture.
The attractiveness of TNDLST is often divided into 4 levels:
▪ Very attractive: there are about 3 rare and endemic species; over 5 recognized beautiful landscapes; there are at least 5 unique natural relics and other natural resources to develop at least 5 types of ecotourism.
▪ Quite attractive: there are about 2 rare and endemic species; there are at least 3 - 5 recognized beautiful landscapes; there are at least 2 unique natural relics and other natural resources that can develop 3 - 5 types of ecotourism.
▪ Attractive: has about 1 rare and endemic species; has at least 1 - 2 recognized beautiful landscapes, has at least 1 unique natural relic and other natural resources that can develop 1 - 2 types of ecotourism.
▪ Less attractive: no rare or endemic species; monotonous natural landscape and can only develop one type of ecotourism.
+ Safety: is an indicator to attract tourists, ensuring ecological and social safety determined by security, politics, social order, and environmental sanitation.
Safety is also divided into the following 4 levels:
▪ Very safe: no cases of ecological insecurity or natural disasters
▪ Quite safe: no cases of ecological insecurity or natural disasters, but there are more street vendors.
▪ Medium: there is begging and street vending.
▪ Poor: there are robberies and threats to the lives of tourists. Drinking water is also not hygienic and does not meet the standards of the World Health Organization (WHO).
+ Sustainability : the sustainability of TNDLST reflects the ability to exist and self-recover of the natural components of the tourist destination against the pressure of tourism activities or other natural, economic and social impacts.
The sustainability of ecotourism is divided into 4 levels:
▪ Very sustainable: no natural components are destroyed, if any, they are at a negligible level and are restored after a short time. DL activities are not affected and can take place continuously for over 100 years.
▪ Quite sustainable: 1 - 2 natural components are slightly destroyed and have the ability to self-recover. DL activities occur regularly from 20 - 100 years.
▪ Medium sustainability: 1 - 2 natural components are significantly damaged and require human assistance to recover. Tourism activities last from 10 - 20 years and may be limited.
▪ Unsustainable: 1 - 2 natural components are severely damaged and require human assistance, but the ability to self-recover is limited and prolonged. Tourism activities are interrupted.
The sustainability of an ecotourism site depends largely on the sensitivity and vulnerability of the ecosystem. For example, coral ecosystems are susceptible to destruction and take a long time to recover naturally, while dry forest or melaleuca forest ecosystems are less susceptible to impacts and recover more quickly when destroyed.
+ Seasonality :
The operating time of ecotourism depends closely on the climate, living habits, and festivals of the local community where ecotourism is developed.
The operating time of the ecotourism site is determined by the appropriate time period of climate and weather conditions for the health and safety of ecotourism visitors as well as the convenient time to take visitors on tours according to the ecotourism program.
The evaluation of the operating time of a DLST point can be divided into 4 levels:
▪ Very long: there are over 200 days a year when tourism activities can be carried out well and there are at least over 180 days when the climate conditions are suitable for human health.
▪ Quite long: there are 150 - 200 days a year that can be used to carry out tourism activities well and 120 - 180 days with climate conditions suitable for human health.
▪ Average: there are 100 - 150 days a year that can be used for tourism activities and 90 - 120 days with climate conditions suitable for human health.
▪ Short: less than 100 days a year can carry out tourism activities well and less than 90 days have climate conditions suitable for human health.
+ Connectivity : is an indicator to evaluate TNDL that helps to connect the
DL points into lines, DL clusters. Connectivity is divided into the following levels:
▪ Very good: there are 5 or more surrounding DL points that can be linked.
▪ Pretty good: there are 3 - 5 surrounding DL points that can be linked.
▪ Average: there are 2 - 3 surrounding DL points that can be linked.
▪ Poor: only 5 DL points or no points, which TNDL can link
Okay.
+ Tourist capacity : refers to the ability to receive visitors of the tourist destination.
reflects the ability and scale of implementing tourism activities without causing negative impacts on resources, environment and society.
In reality, determining the "carrying capacity" of a tourist spot in general and a tourist attraction in particular is very difficult because it requires experimental monitoring. According to many studies, the DL carrying capacity of a tourist spot in general and a tourist attraction in particular is often divided into 4 levels:
▪ Very large: over 1,000 visitors/day
▪ Quite large: from 500 - 1,000 visitors/day
▪ Average: from 100 - 500 visitors/day
▪ Small: less than 100 visitors/day [14].
In addition to the above criteria, tourism exploitation efficiency is also considered an important criterion to consider and evaluate in order to have appropriate exploitation and adjustment measures for each tourism point.
Infrastructure system and technical facilities serving tourism:
- Infrastructure system:
+ Traffic system :
Transportation plays an important role in the development of the tourism industry. The more the transportation industry develops, the more favorable conditions the tourism industry has to develop.
▪ The development of the transportation industry is reflected in the following aspects:
▪ Growth in quantity: the formation of many types of transport and the rapid increase in the number of means of transport.
▪ Development in quality: increase in transportation speed, ensure safety in transportation, ensure convenience in transportation, cheap transportation prices.
+ Communication system:
Communication is responsible for the rapid and timely transmission of news, contributing to the exchange between regions within the country and internationally. A diverse communication system with modern technology is the best way to reach a large number of customers in the fastest time with the lowest cost and the highest efficiency while the world economy is moving towards a knowledge economy.
+ Electricity and water supply system:
When leaving their regular residence to another location, in addition to the needs of food, drink, accommodation, travel, etc., tourists also need to ensure electricity and water for normal living activities. Therefore, electricity and water are also important factors that directly serve the rest and entertainment of visitors. At the same time, the stability of the electricity system creates conditions for
allows the application of modern technologies in management and business, diversifying ecotourism products and services. Moreover, the modern water supply and drainage system also allows for good treatment of wastewater to ensure environmental hygiene at ecotourism sites. Therefore, it can be said that the supply of electricity and water is also one of the important and indispensable factors in tourism development, especially ecotourism.
- DL infrastructure and technical system:
Tourism infrastructure and technical means are all the technical means mobilized to participate in the exploitation of tourism resources to create and implement services and goods to satisfy the service needs of tourists during their journeys. The tourism infrastructure and technical system includes: hotels, restaurants, entertainment areas, means of transportation, ... and also supporting architectural works.
The tourism infrastructure system is a factor that ensures the conditions for tourism production and business activities to be carried out. At the same time, the tourism infrastructure system is also an important factor affecting the level of satisfaction of tourists due to its capacity (meeting the requirements of aesthetics, hygiene, safety) and its convenience. The diversity, richness, modernity, and attractiveness of tourism infrastructure also create the diversity, richness, and attractiveness of tourism services. It can be said that the level of development of tourism infrastructure is a condition and a measure of the level of tourism development of a country.
Other conditions:
- Tourism development policy and strategy :
The tourism development strategy and policy of a country or region is of great significance.
Especially important, it creates the driving force to promote DL development.
The tourism development strategy determines the long-term tourism development directions, referring to the overall issues of tourism development such as tourism product strategy, strategy to improve the quality of tourist services, strategy to preserve, restore and develop natural resources and environment, tourism investment strategy, tourism education and training strategy, tourism market strategy.
- DL human resources :
Tourism in general and ecotourism in particular are industries that employ a lot of workers. The tourism industry is a non-material production industry that provides services to satisfy the needs of tourists. Whether the service is provided well or not is determined by the quantity and quality of tourism staff. For ecotourism, to ensure education and improve understanding for tourists, tour guides, in addition to good foreign language knowledge (including the languages of indigenous peoples), must also be knowledgeable about the natural and cultural characteristics of the local community. Ecotourism operators must cooperate with managers of protected areas and local communities in order to contribute to the long-term protection of the natural and cultural values of the area, improve life, and enhance common understanding between local people and tourists.
- Economic development level and investment capital for tourism :
The tourism industry of a country or region develops in direct proportion to the economic development level of that country or region. The economic development level of a country is high, the activities of the material production sectors have satisfied the needs of society, then that country has the conditions to invest capital in non-material production sectors, including the tourism industry.
1.1.2.4. Impacts of ecotourism activities
Because most of the SPDL and tourism services in general and DLST in particular cannot be stored and are greatly affected by the tourism season, there are months when there is a lot of activity and months when there is little tourism activity. Therefore, tourism businesses are under pressure to earn enough money during the tourism season to cover business expenses outside the tourism season. This is the special characteristic of tourism that makes tourism have a strong impact on the economy, society, environment and even politics.
Impact of tourism on the economy:
- Positive impact :
