摘要
通过开展云南广南1∶5万旧莫幅、董堡幅、马街幅、那洒街幅水文地质环境地质调查工作,查明了区域水文地质条件,进行了地下水系统划分与水资源评价,根据水资源分布及构造条件,查明了工作区主要富水区,并以流域为单元,进行了地下水分区区划;实施了"探采结合井"及地下河开发,服务于地方抗旱成效显著,并总结了应急抗旱找水打井模式;查明了干旱与石漠化是工作区主要环境地质问题。工作的开展为西南岩溶区地下水资源合理开发利用及地质环境综合治理提供了依据。
During the 1：50 000 hydrogeology and environmental geology survey of Jiumo, Dongbao, Majie and Nasajie in Guangnan area, Yunnan province, the regional hydrogeology conditions are found out, the groundwater system are divided and water resources are evaluated. The main water - rich areas are ascertained according to water resources distribution and tectonic conditions, and the groundwater zone is divided by basin unit in the working area. Integrated exploration and developing well construction and underground river development has notable effect on local drought resistance service, and the model of emergency drought resistance, water searching and well drilling is summarized. Drought and rocky desertification have been ascertained as main environmental geological problems in the working area. These provide basis for rational exploitation and utilization of groundwater resources, and comprehensive treatment of geological environment in Karst region of southwest China.
