张掖市实物水供给使用表的编制——SEEAW的初步应用

Compilation of physical water supply and use table in Zhangye City:primary application of SEEAW

联合国水资源环境经济综合核算(SEEAW)整合了水资源环境、经济数据,是唯一在经济账户内说明水供给和使用并支持定量分析的一个综合核算框架。以我国西北干旱内陆河流域张掖市为例,在SEEAW核算框架下衔接现有各专业部门的数据,编制完成SEEAW核心账户——实物水供给使用表。结果显示张掖市社会经济系统用水的突出特点:种植业用水比例过高,水配送以及经济系统内部流量涉及水流量很少,水资源综合利用水平的提高受张掖市工业化、城市化水平低局限,实现水资源可持续利用,提高用水效益需要综合协调社会、经济、生态发展。对今后我国的水核算实践而言,认为在国际标准框架下实现水环境在内的统计指标体系的制度化、规范化,以有效实现数据整合是今后努力方向。

The System of Environmental and Economic Accounting for Water(SEEAW) is a framework focusing exclusively on water resources.SEEAW has a unique contribution because it is the only approach that integrates economic accounts with accounts for water use and supply in a framework.Zhangye City in the arid area in northwestern China is taken as an example.Based on the statistical data from various relevant departments,a physical water supply and use table is compiled.The results show that the characteristics of water use in Zhangye City are as follows: the proportion of farming water is high,and the water distribution and flows within the economic system involve little water quantity.The improvement of the integrated water resources management level needs the promotion of industrialization and urbanization of Zhangye City.The realization of sustainable use of water resources and the promotion of water use efficiency should integrate with the social,economic and ecological development.It is concluded that for the future water accounting practice in China,the institutionalization and standardization of statistical indices including water environment under the framework of international standards should be realized so as to effectively achieve data integration.
