【摘要】：在研究2000—2014年滇池流域水污染排放的时空变化、水环境质量时空变化和生态环境时空演替基础上,结合滇池目前水环境质量监测工作要求,采用模型计算、指标特性分析、专家调查等方法,筛选出36个评价指标,分别表征滇池水环境质量的物理、化学、生物、营养、重金属、有机污染等特性,将滇池湖体4个监测点位优选出的评价指标监测数据输入水生态健康评价系统。结果表明,优选指标和评价体系能全面、准确、宏观地反映滇池水环境质量状况。将滇池评价指标由现有的94个压缩至36个,极大节省人力、物力,且更符合滇池水环境特点。
[Abstract]:Based on the study of the temporal and spatial changes of water pollution discharge, the quality of water environment and the temporal and spatial succession of ecological environment in Dianchi Lake Basin from 2000 to 2014, combined with the requirements of current monitoring work of water environment quality in Dianchi Lake, the model calculation and index characteristic analysis are adopted. Through expert investigation and other methods, 36 evaluation indexes were screened to characterize the physical, chemical, biological, nutritional, heavy metals, organic pollution and other characteristics of the water environment in Dianchi Lake. The monitoring data selected from 4 monitoring points of Dianchi Lake were input into the water ecological health evaluation system. The results show that the optimal selection index and evaluation system can reflect the water environmental quality of Dianchi Lake comprehensively, accurately and macroscopically. The evaluation index of Dianchi Lake is reduced from 94 to 36, which greatly saves manpower, material resources and conforms to the characteristics of water environment of Dianchi Lake.
