水资源核算的水循环机制研究

Mechanism of water cycle under system of environmental-economic accounting for water

从水的自然循环和社会循环出发,针对我国现行水资源统计中存在的水资源内部要素分离统计以及难于与国民经济核算相衔接等缺陷,以水资源环境经济核算理论与方法为依据,通过研究水资源系统(环境)和经济体之间的相互关系,分析了水资源环境经济核算体系框架下水的实物量供给使用表和水资源资产账户的水循环机制,并在国家层面试算的基础上提出进行水资源环境经济核算的建议,以期通过我国水资源环境经济核算体系的建立,完善水资源统计制度,为水资源综合管理提供科学、全面、系统的信息支持。

From the view of natural and artificial water cycles,the relationship between water resources system (environment) and economy was studied based on the principles and methods of the system of environmental-economic accounting for water (SEEAW) considering the defects of separated internal elements of water resources statistic and difficult connection of the information with the system of national accounting (SNA) in China. The mechanism of water cycle in physical water supply and use tables and asset accounts under the framework of SEEAW was analyzed. Rational advices were put forward based on the results of tentative calculation from the national level. It is expected that on the basis of the establishment of SEEAW in China,the system of water resources statistic will be improved so as to provide scientific,comprehensive and systematic information support for the water resource management.
