Study On Ecological Development And Sustainable Development Of Ecotourism In The Yarlung Zangbo Grand Canyon Nature Reserve

In order to explore the harmonious development of ecological and social environment in nature reserves,to achieve the purpose of harmonious coexistence between man and nature,and to achieve the goal of sustainable development of nature reserves.This article takes the Medog in the main area of the Yarlung Zangbo Grand Canyon National Nature Reserve as an example.By investigating the carrying capacity of the ecotourism environment and the level of ecological civilization construction in the Medog area,the relationship between ecotourism and ecological civilization construction in the nature reserve is analyzed.Explore the new model of eco-tourism development in nature reserves from the perspective of ecological civilization,and strive to build a nature reserve system with national parks as the main body.In the study of the environmental carrying capacity of the Medog eco-tourism,25 evaluation indexes were screened by using the analytic hierarchy process.The comprehensive evaluation grade was combined with the degree of membership and the principle of wooden barrels to evaluate the ecological carrying capacity of the Medog tourist destination.The results show that:(1)the eco-tourism carrying capacity of the Medog tourist area is 3.46,which is a slight weak load state;(2)from the degree of membership,the eco-tourism carrying capacity of the Medog tourist area has the highest degree of membership to the slightly weak load,close to Suitable loading;(3)Combining the principle of wooden barrels,it is concluded that the solid waste and accommodation reception rate are the limiting indicators of the environmental carrying capacity of Medog Ecotourism.The level of Medog,s ecological civilization construction is based on a survey of related indicators,and 29 index factors are selected to construct an evaluation system for the level of Medog,s ecological civilization construction,using a combination of Delphi(expert consultation method)and AHP(Analytic Hierarchy Process)Determine the weight of each index and evaluate the level of ecological civilization construction.The results show that:(1)The ecological environment,ecological economy,ecological society,ecological culture,ecological awareness,and ecological landscape scores of the region’s ecological civilization construction level are: 29.27,3.94,6.97,8.59,7.56,20.97,with a total score of 77.30.The level of regional ecological civilization construction is good;(2)The index values show that there is room for construction in terms of ecological economy,ecological society,ecological culture,and ecological awareness.Based on the research results of eco-tourism environmental carrying capacity and eco-civilization construction level,we analyze the complementary relationship between Medog eco-tourism and eco-civilization.Eco-tourism promotes the construction of eco-civilization,and eco-civilization promotes the development of eco-tourism.In order to realize the sustainable development of the Yarlung Zangbo Grand Canyon National Nature Reserve,this article proposes countermeasures for developing ecotourism from the perspective of ecological civilization:(1)improving ecological economic construction and changing the structure of economic development;(2)constructing ecological infrastructure,Promote the development of ecological economy;(3)enhance the residents’ awareness of ecological civilization and build an ecological civilization society;(4)improve ecological security and create a green ecological environment;(5)implement the national park system and build ecological security barriers.
