南四湖地区水资源短缺问题十分严重,20多年来,南四湖上、下级湖水位分别有50％、70％的年份出现低于死水位的情况,1981～1988年期间,经常处于干涸、半干涸状态,这8年中在用水高峰前的3月下旬,南四湖在兴利水位以下累计少蓄水49亿立方米。这一地区由于过量开采,地下水位大幅度下降,济宁附近有2000千方公里,徐州市有200平方公里的漏斗区,枣庄附近出现了地面塌陷。水资源短缺,已严重影响该地区的社会经济发展和人民生活的提高。近十年来,济宁、韩庄、十里泉等电厂因用水量得不到保证,出现了
In the past 20 years, the water level in upper and lower reaches of Nansi Lake has been reduced by 50% and 70%, respectively. During 1981-1988, it was often in a dry state with half Dry state, which in the 8 years before the peak of water in late March, Nansi Lake accumulated less water in the Xingli 4.9 billion cubic meters of water. As a result of over-exploitation in this area, the groundwater level dropped drastically. There are 2,000 square kilometers near Jining and 200 square kilometers of funnel area in Xuzhou. Ground subsidence has occurred near Zaozhuang. The shortage of water resources has seriously affected the socio-economic development of the area and the improvement of people’s living standards. Over the past decade, Jining, Hanzhuang, Shiliquan power plants can not be guaranteed because of water use, there has been
