【摘要】:根据郑州市主要城市河流水环境状况,分析了郑州市地表水和地下水资源时空分布规律、主要城市河流水环境综合水质指数,结果表明:从2012年起,水资源量呈显著下降趋势;郑州市主要城市河流水质污染状况较为严重,综合水质指数呈现逐年下降的趋势,除双洎河和坞罗河综合水质指数处于中等、好以外,其他城市河流综合水质指数处于差、中等水平。采用DPSIR模型对郑州市主要城市河流水环境安全状况进行评价,2009—2011年郑州市主要城市河流水环境安全等级为Ⅳ级,2012年和2013年受大量污染物排入河流影响,水环境安全状况为Ⅴ级,城市水环境状况不容乐观。
[Abstract]:According to the water environment of rivers in main cities of Zhengzhou, the temporal and spatial distribution of surface water and groundwater resources in Zhengzhou is analyzed, and the comprehensive water quality index of main urban rivers is analyzed. The results show that the quantity of water resources has decreased significantly since 2012. The water quality pollution of major urban rivers in Zhengzhou is relatively serious, and the comprehensive water quality index is decreasing year by year. Except for Shuangji River and Wuluo River, the comprehensive water quality index of other urban rivers is poor except Shuangji River and Wuluo River. Medium level. The DPSIR model was used to evaluate the water environment safety of the main urban rivers in Zhengzhou. The water environmental safety level of the major urban rivers in Zhengzhou from 2009 to 2011 was grade 鈪,
