我国水资源质量标准中存在问题探讨

系统分析我国现有涉水质量标准之间的差异性以及各质量标准执行过程中存在的问题。分析表明，当前不同类型的涉水国家标准与行业标准之间的衔接性和科学性较差，标准限值之间存在偏差和矛盾。水利部现有的水资源质量标准在加强饮用水安全保障、评价水资源质量现状和污染物排放方面与现实管理需求存在差距，在不同水域水功能区不同管理要求等方面已不适应当前水资源保护工作的需要。建议在修订现有的水资源质量标准过程中明确水环境保护目标，加强部门间的协调，建立完整、科学、实用的水资源质量标准。

Discussion of problems in water resources quality standards in China

Differences in water quality standards in China and problems in implementation of these standards are systematically analyzed in this paper. The results show that various kinds of national water quality standards and industrial standards lack a connection and are not scientific. This leads to deviations and contradictions between standard limits. The current water resources quality standards established by the Ministry of Water Resources of China are not applicable to the protection of drinking water safety and evaluation of the present situation of water resources quality and pollutant discharge, and cannot meet the requirements of water resources protection at present in different water function zones of various water areas. Therefore, when revising the existing water resources quality standards, the administration departments should determine water environmental protection goals and strengthen coordination to build complete, scientific, and practical water quality standards.
