Study On Evaluation Of Tourism Ecological Security In Shilin County Based On Landscape Pattern

Shilin County has gradually emerged as a problem of ecological environment,which calls for urgent ecological security protection.Based on the theory of landscape ecology and ecological security,this paper introduces ecological security theory into tourism development evaluation and constructs a tourism ecological security evaluation system.According to the characteristics and current status of tourism development in Shilin County,an empirical study was conducted on tourism ecological security in Shilin County.The text consists of 3 parts:In the first part,the landscape pattern of Shilin County was studied from the aspects of landscape pattern composition and landscape pattern index analysis.Type level index and landscape level index were selected respectively.The second part: Based on the study of landscape pattern,the evaluation index system of tourism Eco-safety was constructed,and the indicators that symbolize the Eco-safety of tourism in Shilin County were selected,and the comprehensive evaluation value of tourism Eco-security in Shilin County was obtained.The third part: from the aspects of ecological environment,social and economic analysis for the city,the development of tourism ecological safety problems and challenges,for the sustainable development of each existing problems put forward the corresponding Suggestions.(1)woodland is the landscape matrix of Shilin county.The forest landscape has the largest area and the most significant contributing rate.It influences the composition of the landscape pattern with absolute advantage.The forest landscape has strong stability,the landscape connectivity is the best,and the degree of fragmentation is low.(2)The overall landscape diversity of Shilin county is low,the degree of heterogeneity is low and the degree of fragmentation is high.The landscape structure of Shilin County is relatively fragmented and complex in shape.The borders of various patches are irregular,and the forest landscape in thecountry dominates.In general,the distribution of landscape types is relatively uniform,but the distribution of patches varies among landscape types,and the distribution of patches of most landscape types is distributed.In a random distribution,the degree of fragmentation of the landscape is high;and the landscape diversity is low and the degree of heterogeneity is not high.(3)the tourism ecological security in Shilin county is in a safe state.The overall evaluation value of tourism ecological security in Shilin County is 7.06.From the overall result,the state of ecological security in tourist areas is good,and there is no great threat at present.We should develop resources appropriately and reasonably,and strengthen economic development through tourism development.(4)the advantages and disadvantages of tourism ecological security are obvious.The karst landscape in Shilin county is very rich and the natural environment is good,which is the advantage of sustainable tourism development.But city,high degree of landscape fragmentation,soil erosion,desertification is serious,the economic level is relatively backward,the lack of tourism talents,management and operation system is influence the city tourism ecological safety hidden trouble.(5)environmental governance and market regulation are neck and neck.Natural environment and social economy is hidden trouble,if you need to do both,to improve city tourism ecological security should not only pay attention to environmental governance,reasonable land development,the urban environment construction,etc.;We should strengthen the cultivation of talents,rationalize the management system and regulate the tourism market.
