Evaluation Of The Ecosystem Supply Service Value And Its Influencing Factors In The Tourism Area Of Big Kanas

Ecosystem supply service is the most closely related system of ecosystem that provides all kinds of products for human production and life,and can directly enter the field of production and consumption,and is directly related to human direct consumption.With the rapid development of social economy,the contradiction between economy,resources,population and environment is becoming more and more serious.It is helpful for us to make decisions in ecosystem management and improve the long-term well-being of mankind by reasonably evaluating the ecosystem service value and weighing the change relationship of ecosystem services.The ecosystem service value of Kanas tourist area supply quantitative assessment of ecosystem service value,quantitative supply balance changes,analysis of the factors affecting the change of the value,can guide for the sustainable development of ecological protection and local tourism economy to give theoretical reference and policy.In this paper,in order to supply the big Kanas tourism area service as the main research contents,integration of economic and ecological disciplines,determine the research methods and ideas,through field research,to evaluate the market value of ecosystem services value,the important research results are as follows:（1）based on the carding of summing up a large number of domestic and international ecosystem service value related books and the literature,combined with the actual situation in the study area,the construction of ecological system of Kanas tourist area classification index system of service supply.（2）using the market value method to evaluate the comparable value of the ecosystem supply service of the Kanas tourism area in 1989,2000,2010 and 2016.In 1989,the total value of ecosystem services in Kanas tourism area was 2.43×10¹⁰yuan,2000 was 9.77×10⁹yuan,2010 was 2.06×10¹⁰yuan,2016 was 2.12×10¹⁰yuan,2016,compared with 1989,the comparable value decreased by 3.14.（3）from the overall structure analysis,the supply value of raw materials is the highest in the ecosystem services of the study area,followed by the value of food supply,and the smallest is the value of water supply.In the same year’s value,there are forest volume supply value>forage supply value>animal products supply value>forest by-product supply value>crop supply value>actual water supply value.The economic significance of the supply and service value of the forest ecosystem and the grassland ecosystem is significant.The comparable value of 1989,2000 and 2016 to 2010 was analyzed,and the value of all kinds of supply services changed dynamically in each period.With the supply of ecosystem services in different time on the same time,there is a tradeoff between changes in different kinds of ecosystem services is also there is a tradeoff between short-term and long-term changes,different trade-off relation,the tradeoff between short-term,under external influence can be transformed into a collaborative relationship.（4）The effects of natural climate factors and human social activities on the service value of ecosystem supply in Kanas tourism area were analyzed by qualitative and quantitative analysis.The results showed that climate change,tourism and grazing activities had a two-way influence on supply and service,and the factors of agriculture and animal husbandry and natural climate had great influence on the value of supply service.
