流域水资源共建共享理念与测算方法

Model for calculating benefit and cost sharing of water resources co-conservation in a river basin

本文根据流域水资源共建共享理念,提出了水资源效益分享和成本分摊测算方法。以跨皖浙两省的新安江流域为例,界定了流域水资源共建区与共享区的范围,核算了2006年水源涵养与保护的实际投入。按照受益者分享的水资源效益比例对保护投入进行了分摊,并分析了测算结果的合理性及实施方式,探索了建立和完善全流域水资源保护基金及其使用的管理制度。

Based on the principle that the allocation of water resources benefit among beneficiaries shall be determined according to their corresponding input proportion,a method for calculating the benefit and cost sharing of water resources co-conservation of a river basin is suggested.The model is applied to analyze the sharing of the Xin’an River basin which across the Anhui Province and Zhejiang Province,China.The current territorial scales of the co-conservation area and the benefit sharing area are determined.The total actual water conservation cost in 2006 is calculated and the benefits of water utilization for different beneficiaries are estimated.The conservation cost is allocated to water users or governments in whole sharing area according to the proportion of benefits sharing.The feasibility of the results and corresponding implementation modes are investigated.
