小水滴的奇幻岩溶之旅

The magical Karst tour of little drop

我国西南地区发育着面积广大的亚热带岩溶地貌,峰丛、洼地、溶洞、地下暗河、坡立谷等高度发育,这些千姿百态的岩溶形态在构成独特的地貌景观的同时,也导致了西南岩溶区内"三水"(大气降水-地表水-地下水)的频繁转化。本文从一个小水滴的视角出发,将岩溶区"三水"转化的基本过程进行形象化描述,主要由"洼地内涝""地下暗河""岩溶谷地""溶潭及洞穴鱼""蒸发"等几个内容组成,系统表述了水在大气、地表河流、地下暗河之间的循环历程以及岩溶区典型的岩溶景观和现象。

There are vast subtropical Karst landforms in southwest China,such as peak clusters,depressions,Karst caves,underground subterranean rivers,sloping valleys and so on.These various Karst forms not only constitute a unique landscape,but also lead to the frequent transformation of rainfall,surface water and underground water in southwest Karst area.From the viewpoint of a small drop of water,this paper visualizes the basic process of the transformation of rainfall,surface water and underground water in Karst areas,which is composed of“waterlogging in depressions”,“underground dark river”,“Karst valley”,“Karst pools and cave fish”,“evaporation”.It systematically describes the circulation process of the water in atmosphere,surface river and underground river,and typical Karst landscape and phenomena in Karst area.
