宁夏水环境承载力的定性研究——以COD和氨氮为例

主要介绍水环境承载力的研究背景、水环境承载力的定义、研究现状,以宁夏的水资源状况、自然条件、经济技术水平、科技水平建立水质水环境承载力评价指标体系,确定评价准则.根据统计年鉴、年报、调查的水文资料,选取宁夏地区的五个城市作为宁夏水环境承载力评价单元,分析宁夏市级水环境承载力状况,给出了技术路线图,根据水质水环境承载能力的评价结果,可知宁夏各区(除固原市)及宁夏全区的水质水环境承载力处于"临界超载"状态,其中固原市严重超载.

Qualitative Study on Water Environmental Carrying Capacity for Ningxia

This paper mainly introduces the research background,current status and definition of water environmental carry-ing capacity. The paper takes water resources situation,natural conditions,economic and technological level,science and tech-nology level of Ningxia as the research indies for creating the water environment capacity evaluation system and for determining the evaluation criteria. According to the statistical yearbook,the annual report,the hydrological data of the survey, it selects five a cities in Ningxia province as the evaluation unit to analyze Ningxia municipal water environmental carrying capacity and give the technology roadmap. According to the water quality of the water environment carrying capacity evaluation results,the various re-gions of Ningxia (except Guyuan) are in the "super critical bearing capacity of water environment" state, in which Guyuan is heavily overloaded.
