场效应对现代深部喀斯特发育的控制作用

摘要

This paper studies the controll of the field effect over the modern deep karst development. Among many controlling factors, the moving and soluble water and some other factors are recognized to be the field conditions of the modern deep karst development. To be specific, the field conditions include the water field, the ionic field and the temperature and pressure fields. The study of field conditions is made on the basis of flow dissolution experiment, temperature dissolution experiment and pressure dissolution experiment accordingly. The result shows that the modern deep karst development can be controlled by the dissolution rate of the soluble rocks.%探讨场效应对现代深部喀斯特发育的控制作用,为研究现代深部喀斯特提供理论依据.通过对现代深部喀斯特发育的诸多控制因素研究,将现代深部喀斯特发育控制因素中流动的、具溶蚀能力的水流以及某些外部环境因素归结为现代深部喀斯特发育的场效应,即水流场、离子场、温度及气压场等.通过流速溶蚀实验、温度溶蚀实验、压力溶蚀实验分析研究场效应对现代深部喀斯特发育控制影响.结果表明,场效应主要是通过影响可溶岩的溶蚀速率来控制现代深部喀斯特的发育进程.
