北京奥林匹克森林公园人工湿地生态系统服务非使用价值的评估

介绍了北京奥林匹克森林公园人工湿地的基本概况，论述了该生态系统所具有的服务功能，指出对其美学欣赏、休闲娱乐和科研教育等非使用价值进行评估的重要意义。采用意愿调查评价法(Contingent Valuation Method,CVM)评估了其非使用价值。通过问卷设计、预调查、正式调查、问卷分析，得出支付意愿均值为16023元/（户〖DK1〗·年）；通过进入法(Enter Regression)、逐步分析法(Stepwise Regression)以及部分变量对数化后的逐步分析法等3种多元线性回归分析方式，探讨了支付意愿与受访者社会经济变量的关系，得出最优的回归模型证明对人工湿地越了解、家庭年收入越高以及受教育年限越长的受访者支付意愿就越高。最后，通过选择合理的背景人数，得出在未来20 a内北京奥林匹克森林公园人工湿地的平均总支付意愿为 12336.56 万元/年，总净现值为 189042.97、161427.85 和 139842.25 万元(折现率分别为3%、5%和7%)。〖

ECOSYSTEM SERVICE VALUATION ON NONUSE VALUE FOR THE CONSTRUCTED WETLAND IN BEIJING OLYMPIC FOREST PARK

This paper introduced the main circumstances about the constructed wetland in Beijing Olympic Forest Park (BOFD),and discussed what ecosystem service it possesses,in order to obtain comprehensive value and raise public understanding on it.It is indicated that it’s very important to evaluate ecosystem service nonuse value for BOFP constructed wetland including landscape viewing,entertainment and scientific research and education.Contingent Valuation Method (CVM) was adopted to evaluate the ecosystem service nonuse value for the constructed wetland.After designing relative questionnaires,carrying out prior survey,survey,and analyzing the output,it shows that the mean WTP (willingness to pay) for the BOFP constructed wetland’s ecosystem service nonuse value was 16023 Chinese Yuan/(household〖DK1〗·a).Three Multi Regression analysis methods namely Enter Regression,Step Regression and Step Regression with some variables after logarithm transformation were carried out,which established a good model to confirm that people who have more WTP are more likely to be those who learn more about constructed wetland,have better salaries and have gained better education.By choosing proper context population coming from Beijing city,the total WTP of the BOFP constructed wetland in the following 20 years was acquired as 123.3656 million Chinese Yuan/a and the total Net Present Value were 1890.4297,1614.2785 and 1398.4225 million Chinese Yuan at discount rate of 3%,5% and 7% respectively.
