摘要： 对渭河宝鸡段水质污染情况及变化趋势做出评价，为宝鸡市渭河治理、保护及建设提供一定参考依据。根据2007~2009年渭河宝鸡段6个断面的水质监测资料，采用模糊综合评价法对其进行综合评价，应用秩相关系数法对主要的3个断面的水质在时间上（2002~2009年）的变化趋势进行定量分析。结果表明，所有断面水质达到功能区所要求的水质类别，但存在一定的有机污染；在时间上，渭河宝鸡段污染情况呈下降趋势；在空间上，林家村断面的水质情况最好，胜利桥、常兴桥和卧龙寺断面次之，虢镇桥和蔡家坡断面最差。

Abstract: To evaluate the pollution situation and variation tendency of quality of Weihe River in Baoji Section, using fuzzy synthetic evaluation method to evaluate the water quality of Baoji section of Weihe River based on the observation data of six river segments during 2007-2009. Using rank correlation coefficient method to quantificationally analyze the water quality transform trend of the main three segments during 2002-2009. The results showed that the overall quality of source water achieved to the relevant functional areas of water quality categories, nevertheless organic pollution of source water could not be ignored; the pollution trend of Baoji section of Weihe River was descending; the water quality of Linjiacun segment was the best of all, and then were the Shengliqiao, Changxingqiao and Wolongsi segments, the other segments were the most serious.
