This article in full collection, analysis , Heze City, groundwater recharge, runoff and discharge conditions , based on the use of the target group of aquifer , of Heze City shallow groundwater development horizon thickness , lithology, regional distribution and groundwater type , groundwater level dynamic the characteristics were analyzed . Groundwater monitoring data based on the 1993 to 2003 period , groundwater overdraft area divided , the groundwater level is declining areas including : Peony District of Maling Kong , Juye southern Yuncheng , a single county , Caoxian east, into Wu south. Peony District, eastern , eastern Dingtao single county southeast decline rate of 0.5m / a. Determine the the Heze City shallow pore water overdraft area distribution range . Where the large overdraft area of a single county , an area of 1358km ~ 2, the Juye Matthey, chengwu , Wenshang medium overdraft area , an area of 242km ~ 2 , Peony small overdraft area , an area of 121 km ~ Yuncheng city small the overexploitation District , the area for 71 km to 2 . Overdraft area demarcated for the dynamic monitoring area to calculate the dynamic monitoring area groundwater resources amount to 279 230 000 m to 3 / a , the available groundwater 231,760,000 m to 3 / a , to determine the dynamic monitoring area mining modulus 129,000 m 3/a.km ~ 2 . Overexploitation of the groundwater level on the area of a single county luffing and precipitation , the amount of mining regression model , the groundwater level forecast for . The first program , to maintain the status quo level of exploitation , P = 25 % , P = 50 % , P = 75 % , P = 90 % guaranteed rate of annual precipitation conditions , December 1, 2008 , a single county average groundwater level 1.02m, respectively rebound than December 1, 2005 decreased by 0.63m , 1.65m dropped fell by 2.91m . Under the second program , P = 50% guaranteed rate of precipitation conditions , overexploitation amount each year in turn be reduced by 20 % , 30% , 50% , 80% , 100% , annual groundwater level luffing order -0.17m ,-0.15m,-0.11m,-0.05m,-0.01m. For the over-exploitation of groundwater environment Heze City , the adjustment of industrial structure and the transformation of economic way , the construction of efficient industry, agriculture antifouling system , strengthen the unified management of water resources , water conservation , pollution control and reuse , developing rainwater resources and other countermeasures of the sustainable use of water resources .
