生态补偿是协调环境保护与区域发展机会公平的重要手段.太湖东部湖区是苏州市、嘉兴市和上海市重要饮用水源供给地.本文分析了苏州市滨湖地区水源地水质保护行为与发展权价值损失的关系.应用区域比较法,在地理要素修正的基础上评价了太湖东部水源保护区发展权价值损失,以此作为生态补偿的标准.研究表明,2009年太湖东部地区水质保护行为的发展权损失为42.39亿元,地方财政收入损失占75.88％；农民收入损失占13.58％；城镇居民收入损失占10.53％.为了缩小城乡居民的收入差距,应优先对农民实施生态补偿.水质保护行为产生的外部收益超出了水源供给价值,需要在更大范围内统筹生态补偿问题.%Ecological compensation is an important means to coordinate the contradiction between environmental protection and regional development fairness. Eastern Lake Taihu is an important source of drinking water for Suzhou, Jiaxing and Shanghai cities. This paper analyzes the connection between water quality protection behavior and loss of development right value in Suzhou city. Based on geographic factor correction, the paper applies regional comparison method to evaluate the loss of development right in drinking water source protection region in eastern Lake Taihu, as the standard of eco-compensation. It shows that the loss of development right in eastern Lake Taihu in 2009 is 4.239 billion yuan, while the loss of local fiscal revenue, farmers' income and urban residents' income accounting for 75.88% , 13.58% and 10.53% , respectively. In order to narrow the income gap between urban and rural residents, fanners should be given priority on the implementation of eco-compensation. The external benefit from water protection behavior has beyond the value of water supply, so overall the eco-compensation police in a greater region is needed.
