基于CVM的武汉江汉区绿色生态系统游憩服务价值研究
Study of Recreational Service Value of Urban Green Ecosystem in Jianghan District of Wuhan Based on Contingent Valuation Method

游憩服务是城市绿色生态系统的重要功能。基于条件价值评估法(CVM)，本文采用Spearman相关系数、二元Logistic和有序Ordinal模型，对武汉市江汉区绿色生态系统游憩服务支付意愿及价值进行了研究。结果表明：1) 73.45%的受访居民有支付意愿，居民不愿支付的主要原因是“应由政府出资”，其次是距离较远，可达性较差，从而影响人们的支付意愿；2) 居民支付意愿不仅仅是收入水平的体现，还与年龄、受教育程度等非经济因素相关，江汉区居民支付意愿与再次游憩显著正相关，与年龄、满意度显著负相关，居民的满意度对支付金额有负影响；3) 受访居民支付意愿164.92~224.54元？年？1？人？1，江汉区城市生态系统游憩价值17.76~24.17亿元。
Recreational service is an important function of the urban ecosystem. Based on the conditional value assessment method (CVM), the value and residents’ willingness to pay for the entertainment service of the urban green ecosystem were studied by using the Spearman correlation coefficient, binary logistic and ordered ordinal models. The results showed that: 1) The average probability of respondents expressing a WTP in Jianghan district was 73.45%. “It should be funded by the government” was the main reason why residents were unwilling to pay; secondly, people’s WTP was affected by the long distance and poor accessibility. 2) The probability was not only a reflection of residents’ income level, but also related to non-economic factors such as age and education level. Residents’ WTP had a significant positive correlation with the next recreation, there was a significant negative correlation with the residents’ age and satisfactory evaluation of the green ecosystem, and residents’ satisfactory evaluation had a significant negative impact on amount of the residents’ WTP. 3) The average WTP was 164.92~224.54 yuan per year per person, and the value of recreational in the green ecosystem of Jianghan District was calculated to be 1.76~2.417 billion yuan per year.
