济南明水泉域岩溶地下水数值模拟及泉水水位动态预测
应用地下水模拟软件GMS建立山东济南明水泉域的三维地下水流数值模拟模型,对泉域内岩溶地下水进行数值模拟和水平衡分析,评价了泉域岩溶地下水资源总量和在保持泉水常年喷涌条件下的岩溶地下水可采资源量。在此基础上,应用时间序列分析法对泉水水位动态进行了预测。结果表明:明水泉域多年(2003-2014年)地下水补给量为1.23×10^8 m^3·a~(-1),排泄量为1.36×10^8 m^3·a~(-1),均衡差为-1.30×10^8 m^3·a~(-1);模型预测未来20年泉水最低水位为55.65m,最高水位为68.72m,平均泉流量为34.6×10~4 m^3·d^-1。...

| Bibliography: | 45-1157/P Mingshui spring area, karst, groundwater, numerical simulation The Mingshui spring area is located at the transition zone from the mountainous region to the piedmont tilting plain in central Shandong Province.It is bounded by the Wenzu fault in the west,Yuwangshan fault in the east,metamorphic rocks and the floor of Lower Cambrian series in the south,and the Ordovician limestone roof 600 mbelow surface in the north,respectively,with an area about 660km~2.The overall direction of karst groundwater flow is from south to north in the spring area.The spring water mainly originates from the area with outcropped limestone and abundant karst cracks in the south.The infiltration of precipitation and surface runoff result in abundant karst-crack water.This water flows along the dip direction of strata from south to north.When reaching the most low-lying area in the northern spring area,the karst ground water is blocked by the coal measures strata,and then the water ascends through cracks to become spring group |
