摘要
作者从岩溶水文地球化学为一开放的三相系统出发,重点对桂林岩溶水文地质试验场大气和土壤空气中的CO_2及水的pH值、暂时硬度等进行了现场测试和室内分析;同时将水化学变化规律与土壤CO_2的变化联系起来,对岩溶发育机理作了新的探索。此外,作者还通过岩溶水文地球化学异常对试验场岩溶含水介质的特征及其非均质性进行了分析研究。
Rased on the fact that the karst geochemistry is an open trifacies system, the author made an in-situ measurement and indoor analysis of CO2 in atmosphere and soil air, pH-value and carbonate hardness of water in the Guilin Karst Hydrogeological Experimental Site-Meanwhile, connecting hydrochemistry with CO2 in soil, the author also make a new research on the mechanism of karst development. In addition, the characteristics of water -bearing media and its heterogeneity are identified through karst hydrochemical anomaly.
