摘要
广西凤山县坡心地下河流域岩溶内涝问题突出,内涝具有分布面广、周期性、群发性、治理难度大等特点。本文在分析坡心地下河流域岩溶内涝现状及其特征的基础上,对该流域岩溶内涝的成因进行了分析,结果表明连续高强度降雨、封闭的地形地貌条件、包容式岩溶结构及地下河管道排水不畅等是该流域岩溶内涝形成的主要原因,并针对该流域岩溶内涝的特点,提出了有针对性的防治对策和措施,对指导当地岩溶内涝的综合治理具有重要借鉴作用。
The problem of waterlogging is serious in Poxin Underground River Basin.The waterlogging hazard has the characteristics of wide distribution,recurrent outbreak and being diffcult to control.This paper analyzes the situation and characteristics of karst waterlogging in Poxin Underground River Basin,and discusses the causes of the waterlogging.The results show that the major causes of waterlogging are continuous high intensity rainfall,closed conditions of landform,inclusive type karst structure,the poor drainage capacity of subterranean river pipe and so on.The paper puts forward corresponding countermeasures and measures to guide the local comprehensive control of karst waterlogging.
