岩溶洞穴分类新思考

NEW CONSIDERATION ON CLASSIFICATION OF KARST CAVES

根据一固定流域范围内相对于岩溶合水层的水流运动方式，将洞穴划分为流入、流出和穿越含水层三种类型；并指出：只要外部环境相对稳定，洞穴在流域中所处位置，所执行功能和拥有水动力条件就会随之保持稳定，形成一定成因类型的洞穴，其发育就会表现出很好的延续性和系统性，并展示出相应的形态特征。

From the modern thought of hydrology,the author considers karst caves as the componentlink of water cycle on earth and divides caves developed in a river basin into three main types onthe basis of types of water flow with respect to karstic aquifer system:flowing-through-aquifertype,flowing-out-aqulfer type and flowing-in -aqtiifer type.By the detailed analyses of basiccharacteristics of every type of caves,the author further points out that a cave evolved in a fixedriver basin would keep the same position,execute the same function,and maintain the same hy-drodynamic zonality in the system;and would consequently form a certain genetic type of cave,take a successive and systematic development,and express the corresponding morphologic featuresas long as the outer environment(climate and tectonics)remains relatively stable.
