Estimation of the non-tratable value of Xinjang Tianchi wetland ecosystem service function bassced on the CVM

There are many environmental resources in the Xinjiang Tianchi ecosystem.Because these resources can be used by market exchange,so we can estimate the value of these resources into the currency.The contingent valuation method is a direct approach that can be used to provide non-tratable value of natural resources.In this paper,based on the contingent valuation method,450 questionnaires had been sent out with 412 fed back.The willingness to pay for the protection of Xinjiang Tianchi wetland sustainable development was investigated.The estimated value of the ecosystem services was about 52 million Yuan per year.The research showed that:(1)The mean value of WTP to the ecosystem services of Xinjan Tanchi Wetland was 91.205Yuan(RMB) per person annually;(2) Statistical sample showed the female's willingness to pay was higher than male's.The willingness to pay increased with the education degree,and decreased along with the age and income growth.(3)The age,the monthly income,the level of the education,profession and the level of the understanding to Xinjan Tanchi Wetland were the major factors influencing the willingness to pay.The conclusion would provide beneficial reference for restoring the ecosystem services of Xinjan Tanchi Wetland.
