摘要
调查了秦岭北麓西自宝鸡东至潼关的10县区的28条河流,利用单污染指数法和综合污染指数法进行了评价。研究结果表明:有56.10%的河段受到不同程度的污染,其中水质严重污染的河段占7.32%;中度污染的河段占14.63%;轻污染的河段占34.15%。共有43.90%的河段水质较好,其中水质尚清洁的河段占34.15%;水质清洁的河段占9.76%。不同区县的污染特点不同。宝鸡市陈仓区和渭滨区的河段水体较清洁;西安市所辖户县、周至县、长安区主要以有机污染为主;渭南市所辖潼关、华阴和华县的有机污染和金属污染及氟污染都很严重。
28 rivers of ten counties from west to east in the north piedmont of Qinling Mountain were investigated and assessed by using single -factor polluted index and synthesis polluted index. The results demonstrated that： 56. 10% of the rivers were contaminated to different degrees, among which heavily polluted rivers covered 7.32% ; moderatly polluted rivers covered 14.63% ; lightly polluted rivers cover 34. 15%. 43.90% of the rivers had good -quality fresh water, among.them relatively clear rivers covered 34.15% and clear rivers covered 9.76%. The characteristics of water pollution differed among different counties： In Chencang Section and Weibin Section of Baoji City, the water was relatively clear; in Hu County, Zhouzhi County and Chang＇an County administered by Xi＇an City, there were mainly organic pollution; in Tongguan County, Huayin County and Hua County administered by Weinan City, there were serious heavy metal pollution and florin pollution as well as organic pollution.
