摘要

根据2005-2010年渭河流域(陕西段)26个断面的水质监测资料

采用综合污染指数法、超标倍数法和秩相关系数法等对该段水体进行了评价

对造成渭河水污染严重的化学需氧量(COD)和氨氮(NH3-N)的时空变化趋势和主要污染原因进行了分析。结果表明

渭河流域(陕西段)污染程度基本呈下降趋势

其中宝鸡段水质较好

咸阳至渭南段污染仍然严重;污染减排是促进渭河COD浓度下降的主要原因;渭河干流污染以支流汇入污染为主

渭河干流排污口污染负荷以西安市和咸阳市为主。

Abstract

The methods of comprehensive pollution index

double weight index

and Spearman′s rank correlation coefficient were used to evaluate the spatiotemporal variations in water quality of Weihe River in Shaanxi Province.According to the water quality data collected at 26 monitoring sections from 2005 to 2010

the temporal and spatial trends of COD and NH3-N and the driving forces were analyzed respectively.The results indicated that the overall water quality has improved certainly as shown by the reduction of COD.The water quality of Baoji section was classified as of the third grade.However

the pollution level in the section from Xianyang to Weinan City was still quite high.The polluted tributaries and drainage outlets in the areas of Xi′an and Xianyang City contributed mainly the pollution in the mainstream.
