莒南县十字路镇面积80km~2,其中山丘区58km~2,现有土地面积3333km~2。全镇地表水资源仅靠官庄、赤石沟、东西芦林、兴隆店子等8座小水库,当保证率p=75％可供水资源量不足170万m~3,且在地域分布上极不均匀,相互统配不可能。由于受水文地质条件的制约,地下水相当贫乏,全镇地下水多年平均可采量1028万m~3,多分布于平原区。主要靠降水补给。当p=75％时,地下水可供量不足800万m~3,地表水地下水总量亩均
Junan County Cross Road Town area of 80km ~ 2, of which 58km ~ 2 hills, the existing land area of 3333km ~ 2. The surface water resources of the town rely on only 8 small reservoirs of Guanzhuang, Arsenicum, Lulu, Xinglongdian, etc. When the guaranteed rate is p = 75% and the available water resources is less than 1.7 million m ~ 3, Uneven, mutual unification impossible. Due to the constraints of hydrogeological conditions, groundwater is rather poor. The average recoverable amount of groundwater in the town is 10.28 million m ~ 3, mostly distributed in plain areas. Mainly rely on precipitation recharge. When p = 75%, the available groundwater is less than 8 million m ~ 3, and the total surface water of groundwater is mu
