0引言商丘市是一个典型的农业大市,因受季风气候的影响,降水偏少,蒸发量大,地下水不能充分补给,旱灾比较频繁。全市多年平均水资源总量22.84亿m3,人均占有量仅有287 m3,亩均占有量仅有244 m3,仅占全国人均12%,耕地亩均14%。特别是20世纪80年代初以来,随着工农业生产用水和人民生活用水的增加,致使水资源超量开采,地下水位下降,城区地下水降落漏斗面积增大,大量机井出水量减少,许多水利设施不能充分发挥作 0 Introduction Shangqiu is a typical agricultural market, due to the monsoon climate, less rainfall, evaporation, groundwater can not be fully recharged, drought more frequently. The city’s average annual water resources total 2.228 billion m3, average per capita is only 287 m3, the average amount of mu is only 244 m3, accounting for only 12% of the national average, 14% of the mu of cultivated land. Especially since the early 1980s, with the increase of industrial and agricultural production water and people’s daily use of water, over-exploitation of water resources, lowering of groundwater table, increase of groundwater funnel area in urban area and reduction of water discharge in a large number of machine wells have prevented many water conservancy facilities from Give full play
