    摘要:

    分析了2001—2012年郑州市水资源变化情况、社会用水变化情况以及废污水排放与河流水质变化情况。结果表明:(1)郑州市降水量平水年占41.67%,地表水资源量偏枯和枯水年份占83%,地下水资源量低于多年平均值的年份占50%,年平均水资源总量低于多年平均水资源总量11.25%。(2)社会总用水量、工业用水量和生活用水量明显增加;呈稳步上升趋势,农业用水量明显减少,呈明显下降趋势。社会用水由以农业用水为主导向以工业用水为主导转变,用水水源主要来自地下水。(3)废污水排放量呈明显增加趋势,主要河流水污染严重,基本达不到水资源功能区要求。针对水资源开发利用中存在的问题,提出了对策建议:(1)水资源短缺矛盾尖锐,要开源补水;(2)废污水处理落后,要治污清源;(3)地下水开采量大,要减采补水。

    Abstract:

    The changing trends of society water use, wastewater emission and river water quality are analyzed in Zhengzhou during the period of 2001-2012. This study result shows: (1) The normal years of the total precipitation for many years accounted for 41. 67%. The low-flow and dry year of the surface water resources for many years accounted for 83%. And the year of the groundwater resources below the average for many years accounted for 50%. The average annual amount of water resources is lower than the average for many years about 11. 25%. (2) The survey also reflects an apparently increase and upward trend in water consumption in society industrial and domestic water use while the water consumption of agricultural production has been being decreased and dropped considerably in recent years. Therefore the dominant of water utilization is transformed from agricultural water to industrial water. The sources of water in society are mainly from groundwater. (3) The amount of the wastewater emission are still on increasing trend, therefore, water in the main rivers have been severely polluted and can not suit the needs as the water resource function zones. Three questions and suggestions in the development and utilization of water resources are proposed: (1) With the acceleration of the shortage of water resources, it is needed to explore more water resources and get some supplement of water. (2) The treatment of the wastewater emission are insufficient, so it is needed to manage the treatment of the wastewater emission and protect the water sources. (3) Along with the groundwater mining quantity increasing massively, it is needed to reduce the groundwater mining and get some supplement of water.
