摘要
城市水源地建设保护对于维系城市水资源可持续供给具有重要意义。城市水源地建设保护同时又对当地居民施加了一系列负面外部影响,削弱了城市水资源供给的可持续性。以首都水源地为例,利用条件价值评价法(CVM)衡量水源地建设保护对水库周边农户的负的外部影响,通过回归分析得到影响水源地调查者受偿意愿的因素,据此得到受偿意愿函数的各项参数,进而计算水源地居民受偿意愿数量,经计算当前该值约为94050128.16元,以此作为对水源地建设保护过程中外部成本的度量。
Urban water sources are of great importance to maintain the sustainable water supply to the city. While the construction and protection of water sources usually imposes a series of negative external influences on the local residents, which weakens the sustainability of water supply. As one of important capital water sources, Miyun was chosen as a case, where contingent valuation method was used to estimate negative external influences from the construction and protection of the capital water sources on the local farmers. The factors influencing the interviewee＇s willingness to accept （WTA） were identified through regression analysis, together with the coefficients of the function of WTA. Then the amount of the interviewee＇s WTA as the estimate of external costs was calculated with the result around 90 million Yuan.
