【摘要】 峰林平原区是广西分布较广的一种岩溶地貌,该区人口密集,土地资源丰富,但受岩溶发育强烈影响,往往地表水缺乏,地下水资源十分丰富。地下水主要赋存于网络状岩溶裂隙中,岩溶含水层给水度大,透水性好,水力坡度缓,地下水分布均匀,钻探成井率高。同时,地下水埋藏比较浅,岩溶发育深度小于100m,采用20～70m的钻井就可以开采,取水成本低。因此,可以通过钻孔取水工程,建设"抽水型"地下调节水库,来解决岩溶峰林区干旱问题。更多还原

【Abstract】 Fenglin plain is a karst landform widely distributed in Guangxi.The area is densely populated and rich in land resources.However,under the strong influence of karst development,surface water is often scarce and groundwater resources are abundant.Groundwater mainly occurs in network-like karst fissures.Karst aquifer has large specific yield,good permeability,slow hydraulic gradient,uniform groundwater distribution and high drilling rate.At the same time,the underground water is relatively shallow and the karst development depth is less than 100 m,which can be mined by 20-50 mdrilling,with low water intake cost.Therefore,the problem of drought in karst peak forest region can be solved by drilling water intake project and constructing"pumping type"underground regulating reservoir.更多还原
