基于CVM的新疆天池湿地生态系统服务功能非使用价值评估

新疆天池湿地拥有大量的环境资源,但由于这些资源中很多不能进行市场交换,所以无法直接进行货币化评价。条件价值评估法(CVM)是当前可用于确定环境物品非市场和非使用价值的有效方法。文中采用条件价值评估法,于2011年8月,在新疆天池景区发放了450份CVM问卷,共回收412份有效问卷。分析了保护新疆天池湿地永续发展的支付意愿,并对新疆天池湿地的生态系统服务功能非使用价值进行估算,得出新疆天池生态系统服务功能非使用价值约为0.52亿元/年。研究表明:1)游客对保护天池永续发展的平均支付意愿为91.205元。2)统计样本显示:男性的支付意愿略高于女性的支付意愿;支付意愿随着被调查者的受教育程度的上升呈上升趋势;支付意愿随着被调查者对天池湿地了解程度的深入呈上升趋势;支付意愿随着被调查者的年龄与月收入的增长呈下降趋势。3)受访问者的年龄、月收入、受教育程度、职业及对天池的了解程度对支付意愿有显著影响。希望通过此研究能够为新疆天池湿地保护区生态修复建设提供一定的参考依据。

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.
