城市绿色生态系统休憩娱乐服务支付意愿及价值评估——以武汉市汉阳区为例

Willingness-to-Pay for Recreation Services of Urban Green Ecosystem and Its Value Assessment: A Case Study in Hanyang District of Wuhan City, China

摘要: 以武汉市汉阳区为例，采用CVM调查，利用二元Logistic模型、有序Ordinal模型分析居民对汉阳区城市生态系统休憩娱乐服务的支付意愿与影响因素，并对其价值进行评估。结果表明：1) 收入水平对支付意愿和支付金额有显著正影响，随着收入水平的提高，支付意愿加强，支付金额增加。支付意愿和支付金额还与受访者对汉阳区城市绿色生态系统的满意程度呈正相关。受访者常住地对支付意愿呈显著负影响；2) 受访者对汉阳区绿色生态系统有较高支付意愿，其中有正支付意愿的占比76.9%，不愿支付的主要原因“应由政府出资”占比35.5%；受访者年龄、月均收入和再次游憩对支付意愿有显著负影响；3) 通过CVM估算得其休憩娱乐服务经济价值为10.59~13.77亿元。
