摘要
在简述滇中地区自然地理、岩溶水文地质基本特征的基础上,结合野外现场调查及室内岩石、水化学样品的测试分析,查明了研究区可溶岩地层的岩性组合状况、地质构造特征、地表水体分布情况、地下水的补给、径流、排泄条件,基本查明了岩溶的类型为HCO_3-Ca·Mg、HCO_3-Mg·Ca、HCO_3-Ca型,可溶岩在不同地区呈不同发育规律,并分析了在地下水的补给来源主要为大气降水。
The geographic, karst hydro-geologic basic characteristics in middle Yunnan Province has been described. Combined with the data of the field investigation and indoor rock, water chemistry samples test analysis, the lithology combination condition, geological structural features, surface water distribution, groundwater recharge, runoff and discharge conditions have been studied. The basic types of karst include HCO_3·Ca·Mg·HCO_3-Mg·Ca type and HCO_3Ca, and the lava in different regions showed different developmental rules, and the recharge source of groundwater is defined mainly as the meteoric water.
