【摘要】：根據(jù)鄭州市主要城市河流水環(huán)境狀況,分析了鄭州市地表水和地下水資源時空分布規(guī)律、主要城市河流水環(huán)境綜合水質(zhì)指數(shù),結(jié)果表明:從2012年起,水資源量呈顯著下降趨勢;鄭州市主要城市河流水質(zhì)污染狀況較為嚴重,綜合水質(zhì)指數(shù)呈現(xiàn)逐年下降的趨勢,除雙洎河和塢羅河綜合水質(zhì)指數(shù)處于中等、好以外,其他城市河流綜合水質(zhì)指數(shù)處于差、中等水平。采用DPSIR模型對鄭州市主要城市河流水環(huán)境安全狀況進行評價,2009—2011年鄭州市主要城市河流水環(huán)境安全等級為Ⅳ級,2012年和2013年受大量污染物排入河流影響,水環(huán)境安全狀況為Ⅴ級,城市水環(huán)境狀況不容樂觀。
[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，
