云南省地表水水质评价

Evaluation for surface water quality of Yunnan Province

以云南省2000～2009年主要水质参数的监测数据为依据,采用指数法、单指标评价法、季节性Kendall检验法等方法,对云南省地表水水功能区水质类别、水质达标情况、水质变化趋势、饮用水源地水质、湖库营养化状况等方面进行了评价和分析。水质评价分析体现了历史(趋势)与现状结合、水质水量结合、水资源质量与功能使用结合的原则。通过对结果的研究,明确了云南水功能区现状、达标比例、污染物特征、水源地水质合格比例等重要参数,对今后水资源管理保护具有重要指导意义。

Based on the main surface water quality monitoring data during 2000 ~ 2009 in Yunnan Province, the analysis and evaluation on the surface water quality of Yunnan is carried out by index method, single index evaluation method, seasonal Ken- dal! method, the evaluating contents including water quality type, standard - reach, water quality trend analysis, water quality of drinking water sources, eutrophication of lakes and reservoirs. In the evaluation, the principles of integration of historic trend and present status, integration of water quality and quantity, integration of water quality and water sources function are paid attention to. By the research, some significant parameters are determined such as present status of water function area, standard - reach ratio, characteristics of pollutants, providing references for the future water resources management.
