目前,山东省地下水位普遍下降,有的地区竟下降达6米之多,以致造成农作物灌溉用水短缺,人畜吃水困难。据调查,地下水位之所以持续下降,除去近几年降水偏少,而开采量不断增加外,过度地扒山皮、刨草根,毁林毁草开荒、开矿、采石等,也是一个重要原因。由于林草植被的破坏,降雨时(尤其是暴雨),雨点直接撞击地面,地表径流量加大,地下水的补给量相应减少。与此同时,由于地表水源短缺,便人为地增大了对地下水的开采量。越开采,地下水位越下降,旱情越严
At present, the water table in Shandong Province has generally dropped. In some areas, it has actually dropped by as much as 6 meters. As a result, there is a shortage of irrigation water for crops and difficulties for people and animals to draft. According to the survey, the reason why the groundwater level continued to decline is not only the lack of precipitation in recent years, but the continuous increase in the amount of mining. It is also an important reason that excessive excavation of mountain skins, planing grass roots, deforestation and wasteland destruction, mining and quarrying etc. . Due to the destruction of forest and grass vegetation, rainfall (especially heavy rain), raindrops hit the ground directly, surface runoff increased, a corresponding reduction in groundwater recharge. At the same time, groundwater extraction has been artificially increased due to the shortage of surface water. The more mining, the more the groundwater level decline, the more severe the drought
