太原市地表水功能区水质评价及达标分析

Water Quality Evaluation and Standard Analysis of Surface Water Functional Region in Taiyuan City

以2013年的水质监测数据为依据,采用单因子评价法、平均污染指数法对太原市地表水功能区水质现状进行了评价,并结合水功能区的水质目标对其进行了达标分析。同时利用2004-2013年的水质资料通过平均污染指数对水功能区近10年的水质变化趋势进行了分析。结果表明,太原市地表水功能区水质达标率相对较低,水质污染虽呈下降趋势,但污染仍较严重。文中对水功能区水质达标率低的原因进行了分析,提出了改善水质状况的措施与建议。

Based on water quality monitoring data in 2013, the current situation of water quality of surface water functional region in Taiyuan city was evaluated using single factor evaluation method and average pollution index method, and standard analysis was carried out combining with water quality target in surface water functional region. The water quality data in 2004-2013 was used to analyze the water quality variation trend in recent decade using average pollution index. The results show that the control rate of water quality of surface water functional region in Taiyuan city is relatively low. Although water contamination presents a downward trend, the pollution is still serious. This paper analyzed the reason for low control rate of water quality in water functional region, and proposed measures and suggestions to improve water quality status.
