摘　　要：针对资源环境经济评价中存在的资源耗减成本难以估价的问题,基于水资源环境经济核算研究,从水资源的商品流通性出发,提出以影子价格评价水资源价值的思路。分析了水资源耗减的基本概念,并以水资源耗减量计算为基础,提出了水资源耗减成本计算方法。最后对全国以及一级流域进行了估算和分析,结果表明:2005年我国水资源耗减成本达到了1647亿元,占总GDP的0.91%;在各一级流域中,海河流域水资源耗减成本最高,达到了768.6亿元,约占其GDP的2.92%,这客观反映出海河流域水资源短缺问题。水资源耗减成本方法可以完善综合环境经济核算中价值量核算的研究。Aiming at the critical issue that the cost of water resources depletion（CWRD）is difficult to be evaluated in System of Integrated Environmental-Economic Accounting（SEEA）at present,this study proposes a calculation method based on the research on system of environmental-economic accounting for water（SEEAW）of China in recent years.According to the negotiability of water resources,a theory of which to evaluate value of water resources by shadow price was suggested.Mean while based on the concept and quantity of water resources depletion（WRD）,a method to calculate CWRD by value of water resources and WRD was proposed.It shows that the CWRD of China is 164.7 billion yuan or 0.91% of GDP in 2005.Among the first-level river basins in China,the CWRD of Haihe River is the highest,reaching 76.9 billion yuan or 2.92% of GDP of the Haihe River basin.It shows the situation of water shortage in the Haihe River basin.Meanwhile,the approach was applied to estimate the CWRD in the whole mainland of China and the first-level river basin.
