摘要生态系统服务价值估算是当今世界生态经济学研究的热点之一。湿地作为世界三大生态系统之一,正面临着巨大的威胁,因此对湿地生态系统服务价值进行调查与评价具有重要的理论和现实意义。本文以西溪湿地为例,采用条件价值评估法(contingent valuation method,CVM),通过调查当地居民的支付意愿及消费意愿来反映该区域的生态系统服务价值,并用SPSS18.0 对数据进行多元线性回归分析,探究其与社会经济变量之间的关系。结果表明:(1)西溪湿地的平均支付意愿为70.64元/月/户,平均消费意愿为232.67元/人/次。(2)消费意愿的样本离散程度远远大于支付意愿,其多元回归分析未通过F检验,模型无效。(3)支付意愿的有效多元回归模型显示,人们对西溪湿地的了解程度、游玩意愿、教育程度与支付意愿呈正相关关系,年龄、对市政府部门进行治理的信任程度与其呈负相关关系。(4)在社会经济因素中,受教育程度影响程度最大,其次为对政府部门的信任程度,影响相对最小的为游玩意愿。 46946
Ecosystem service value calculation is one of the focuses of ecological economics. Wetland, as one of the three ecological systems of the world, is facing a huge threat, so the investigation and evaluation of wetland ecosystem service value is of important theoretical and realistic significance. Taking Xixi wetland as an example, using the contingent valuation method (CVM), through the investigation of local residents' willingness to pay (WTP) and willingness to spend to reflect the regional ecosystem services value, using SPSS18.0 to multivariate linear regression analysis of data, explore its relationship with the social and economic variables. The results show that: (1)The average willingness to pay for Xixi wetland is 70.64 RMB per month per home, willingness to spend is 232.67 RMB per person per time on average. (2)The sample dispersion degree of willingness to spend far outweigh the WTP,and its multiple regression analysis hasn’t through F test, so the model is invalid. (3) The valid multivariate regression model of the WTP shows that the understanding of the Xixi wetland, play will, educational degree and willingness to pay are positively correlated relationship, age, the degree of the trust of the governance of the municipal government departments are negatively related to it. (4) In the social and economic factors, affected by the educational degree is the largest, followed by one’s trust in the government departments, relative least intend to visit.
