表层岩溶带及其水循环的研究进展与发展方向

A REVIEW ON RECENT ADVANCES AND PERSPECTIVE IN EPIKARST WATER STUDY

表层岩溶带是现代岩溶学一个很重要的概念,表层岩溶水对于解决西南岩溶山区居民的干旱缺水问题具有重要意义。近年来,不但揭示了表层岩溶带的特征、形成的动力条件机理及其含水层特征、开展了表层岩溶的自动化监测、研究了表层岩溶水与生态环境的相关性,还对西南表层岩溶水资源进行了初步评价。今后一段时期内表层岩溶水的主要研究方向是开展表层岩溶水与管道水的耦合关系研究、生态环境调蓄表层岩溶水的功能研究及表层岩溶水资源评价。

Epikarst zone is an important term of the modern karstology.The epikarst water has important significance to the water supply for local people in southwest China karst mountainous area.In recent years,karst experts not only have studied the features,karst dynamic conditions,formation mechanism and aquifers of the epikarst zone,relationship between epikarst water and ecological environments,but also monitored changes of the epikarst water.The epikarst water resources in southwest China have been primarily estimated.In the next decade,the coupling relationship between epikarst water and conduit water,the function of ecological environment to adjust epikarst water and the detailed evaluation of the epikarst water resources will be key points in the epikarst researches.
