| 针对综合环境经济核算中存在的资源耗减成本难以估价的突出问题，基于近几年开展的水资源环境经济核算研究工作，从水资源的可更新性出发，提出了由于人类经济社会活动用水消耗所产生的水资源耗减的基本概念
以及相应的水资源耗减量分析计算方法，并以全国和海河流域为例进行了估算和分析，分析结果表明，从不同水源的可更新性差异考虑，分别计算地表水、浅层地下水和深层地下水耗减量，其结果更为客观、合理；经计算，
全国水资源耗减总量为247亿m3，其中海河流域为104亿m3。水资源耗减量的确定，将为综合环境经济核算中水资源耗减成本的核算和水资源可持续利用的量化研究提供依据。 |

| Aiming at the critical issue that the cost of water depletion（WD）is difficult to be evaluated in
system of environmental-economic accounting （SEEA） at present，this study proposes the concept of WD caused by water consumption of human activities and its calculation approach from the view point of water resources renewability based on the research project of system of environmental-economic accounting for water in China. Meanwhile，the approach was applied to estimate the quantity of WD in whole China mainland and the Haihe river basin. The result shows that depletion of surface water，shallow groundwater and deep groundwater analyzed separately would be more reasonable since their difference of renewability was considered. The total amount of WD in China is 24.7 billion cubic meters，in which，10.4 billion cubic meter is in Haihe river basin. Determination of quantity of WD will provide the basis for its cost accounts in SEEA and to quantify the sustainability of water resources utilization. |
