基于水资源核算的太湖流域水环境退化成本分析

为合理制定流域水价,加强流域水资源统一管理,提高水资源节约利用水平,促进水资源可持续利用,对水环境与经济社会产生的关系进行综合考量;在核算太湖流域2010年水资源的基础上,分别利用基于防护费用的评估方法和基于损害的水环境退化估价方法,计算分析2010年太湖流域水环境退化成本。结果表明:对污染物进行源头治理不仅是出于对环境保护的考虑,更是尽可能地降低水环境退化成本、避免经济损失的最佳选择。水环境退化分析为合理制定水价及水资源统一管理提供了重要参考。

Study on water environmental degradation cost in Taihu Basin based on water resources accounting

In order to make reasonable water price, strengthen the unified basin water resources management, increase the water conservation utilization level and promote sustainable utilization of water resources, the relationship between water environment and economic society is considered. Based on accounting water resources of Taihu basin in 2010, the protection cost evaluation method and the damage of water environment estimating method are adopted to calculate and analyze water environmental degradation cost of Taihu basin in 2010. The results show that: pollution source management is not only out of consideration for environment protection, but also for reducing water environmental degradation cost as much as possible, which is the best choice to avoid economic losses. Water environment degradation analysis provides an important reference for making reasonable water price and water resources unified management.
