Integrated Assessment of Water Resources in Zhengzhou, China


Due to frequently interaction between surface water and groundwater, water resources in Zhengzhou are assessed by an integration of surface water and groundwater, water quantity and quality and their distribution characters of quantity in different quality. The assessed results show that the average of the total amount of water resources from 1956 to 2005 in Zhengzhou is 1280.40×106 m3∕year, where surface water resources is 703.60×106 m3∕year, groundwater resources is 772.32×106 m3∕year, and the repetitive calculation is 152.55×106 m3∕year. The integrated water quality is from grade III to grade V. Apart from grade III in Yinghe zone and grade IV in Huaxia zone, the rest is of grade V. The water resources of grade III is 267.69×106 m3∕year, grade IV is 416.07×106 m3∕year, grade V is 246.72×106 m3∕year, and worse than grade V is 349.93×106 m3∕year (mostly surface water).
