1 目前的水资源状况开封市的多年平均降水量为651.9mm。多年的平均水资源量为12.20亿m~3,人均只有291.3m~3,农田灌溉平均用水量230.6m~3,万元GDP(2000年)用水量678.2m~3。从人均拥有量来看,开封市是一个水资源极度贫乏的城市,也是一个资源型缺水的城市,而且水资源在时空分布上也不均匀;水资源的开发利用程度不高,地下水开采量过大,地下水下降漏斗区域不断扩大,主要靠引黄补济。水质方面亦有不同程度污染,根据开封市水质监测资料显示:地下水仅有35%达到饮用标准,黄河
1 Current water resources Kaifeng City, the average annual rainfall of 651.9mm. The average water resources for many years is 1.220 billion m 3, with average per capita of only 291.3 m 3, average water consumption of farmland irrigation is 230.6 m 3, and water consumption of 6,000 yuan (2000) is 678.2 m 3. From the per capita possession of view, Kaifeng City is an extremely poor water resources in cities, but also a resource-poor cities, but also in the spatial and temporal distribution of water resources are not uniform; the development and utilization of water resources is not high, the amount of groundwater exploitation Too large, groundwater down the funnel area continues to expand, mainly by Yin Huangji. Water quality also have different degrees of pollution, according to Kaifeng City, water quality monitoring data show that only 35% of groundwater to drinking standards, the Yellow River
