1、银川城市发展对黄河银川段水质影响研究 摘要：黄河作为银川重要的地表水资源，为银川市经济社会发展提供了重要的保障和支撑，随着经济社会的迅速发展，各类污染的产生量和排放量逐渐增多，对黄河水质造成了较大压力。本文根据2006-2010年银川段黄河断面的监测数据，运用因子分析法对银川市2006-2010年的黄河银川段的水质进行了综合评价,结合水质综合污染指数与灰色系统理论对银川段黄河水质和城市化水平进行了灰色关联度的计算和分析。结果显示，银川市城市化所带来的经济增长很大程度上影响了银川段黄河水质。通过灰色关联度分析方法，得出银川社会、经济因素对黄河水质的影响
2、程度大小依次是为年污水排放量＞工业生产总值＞总人口＞地区生产总值＞城市化率。可以看出影响黄河银川段水质的主要因素是污水排放总量，在实现污染物达标排放的前提下，要进一步加大污染物总量控制的目标。协调城市化发展和城市地表水环境之间的矛盾,减少污染,提高污水的重复利用率，提高用水效率，减少污水排放量，努力实现城市发展与环境保护的双赢。关键词：黄河、水质、城市发展、银川市Abstract:TheYellowRiverYinchuanastheimportantsurfacewaterresources,providesthe16importantguarant
