黄河流域长孝岩溶水系统水文地质特征及蓄水模式分析OA

Based on hydrogeological survey with the scale of l:50 000 conducted in Changxiao karst water system in the Yellow River basin,the boundary conditions,distribution of water bearing rock formations,and spatial distribution characteristics of water richness of the hydrogeological unit have been summarized,groundwater recharge,runoff,discharge conditions,and dynamic changes in the area have been analyzed,and the interaction between the Yellow River and surrounding groundwater has been studied.The Yellow River supplies pore water to the north and pore water and karst water to the south.The range of lateral seepage supply zone for pore water is Wangying village-Pangdaokou-Taipingzhuang-Yaohemen village.The supply of karst water mainly occurs in the area from Wangkoushan village to Liuhequan village and near Shengli village in Xiaoli town.The fractured karst water rich area are Duandian village in Shuangquan town,with Zhushadong formation as the water bearing rock group,and Guide-Xiaoli-Maji fractured karst water rich area with Sanshanzi formation-Majiagou group as the water bearing rock group.Water rich mechanism has been analyzed.Two types of bedrock water storage structures have been summarized,they are interlayer karst-fault water blocking type and monoclinic-fault type.It will provide some refer-ences for water exploration and well location in this area.
