跨流域调水水源区生态补偿偿付意愿及其差异性分析研究--以扬州市为例

Study on Willingness and Difference of Ecological Compensation in Water Source Areas of Interbasin Water Transfer--A Case of Yangzhou City

水源地居民既是环境资源的享用者,又是环境改善的受益者,为了推进水源区生态补偿机制的建立,公众意愿的分析研究就显得非常迫切。基于条件价值法对南水北调东线源头区扬州市公众的生态补偿意愿进行问卷调查,利用非参数估计法和参数模型法测算了水源区居民生态补偿支付意愿(WTP)和受偿意愿(WTA)。结果表明:在442份有效样本中,居民具有支付意愿和受偿意愿的比例分别为76.70%和75.11%,通过非参数法和参数法结合得到的WTP和WTA值分别为206.47元/(人·年)和449.30元/(人·年),WTA/WTP值为2.18,最后提出相关的政策建议。通过对扬州市居民生态补偿偿付意愿及其差异性分析,旨在为深入研究南水北调东线工程沿线公众参与流域生态补偿甚至更大范围的社会公共管理提供参考。
