贵州省挂丁幅区域地下水现况与开发利用研究
Study on the Present Status and Development and Utilization of Groundwater in the Guading Area of Guizhou Province

本文以贵州省挂丁幅区域为研究对象，对区内地下水现状与开发利用进行调查研究，在现有的资料基础上，开展大量野外核查工作和对空白区补充调查工作，分析地下水水位、水量及水质变化情况、趋势，调查地下水开发利用现状、方式，并提出开发利用建议。研究结果表明：区域的地下水水位整体呈下降趋势，地下水质量整体良好，参评的41组地下水样品中，IV类水有3组，其中IV类水超标因子为Al、Pb、Hg。研究区生活用水以地下水开发为主，地下水机井资源开发利用较少，开发潜力较大。本研究进一步提高区内地下水研究程度，实现新一轮地下水基础资料的更新，服务于社会经济可持续发展，可作为区内国土资源开发与整治规划、城镇与重大工程规划布局、环境保护与生态建设等的参考依据。
In this study, the present situation, development and utilization of groundwater in Guading region of Guizhou Province were investigated. Based upon the current data, plenty of field verification and sup-plementary work were carried out for the blank area, and the change and trend of groundwater level, water quantity and water quality were analyzed. In addition, the current situation of groundwater de-velopment and utilization, and future development and utilization suggestions were provided. The re-sults show that the groundwater level in the region is decreasing as a whole, and the groundwater quality is generally good. Among the 41 groundwater samples, there are 3 samples of class IV water, of which the exceeding standard factors are Al, Pb and Hg. In the study areas, the water for living is mainly provided by groundwater, the development and utilization of groundwater resources are less, indicating the development potential is greater. This study further improves groundwater research in the region, updates basic data of groundwater, serves the sustainable development of social economy, and can be used as a reference for the development and regulation planning of land resources, the planning and layout of towns and major projects, environmental protection and ecological construction in the region.
