| 摘 要： | 阐述广西溶洼系统的结构特征，认为溶洼系统所处的位置高度、地层岩性、岩溶发育程度及地下水埋藏深度，特别是落水洞、坚井、天窗、漏斗、地下河道发育的形态和大小是形成内涝的内在因素。不合理地平整土地、固体废弃物随意倾倒、修建大型水库、上游洼地不合理的隧洞排洪、破坏森林植被等人类活动也会引发溶洼系统结构变化，导致溶洼系统的输水能力变差，加剧岩溶内涝发生，加重内涝灾害程度。

| Abstract: | The structure characteristic of the karst depression system (KDS) in Guangxi is expounded The environmental factors of the KDS,such as positional elevation,stratum lithology,karst development and depth of groundwater,particularly the shape and size of avens, silos,dormers,groundwater channels,are the intrinsic factors causing waterlogging The KDS structure would be changed due to the human improperly activities such as irrationally level off land,unbending placement of solid castoff,establishment of great reservoirs,irrational flood ejection by tunnel in the depression of the upper river,forest breakage That would lead to poor water flow and aggravate waterlogging disaster |
