以吉林省水文地质单元界线为基础,统计查阅各地级行政区地下水种类,富水程度、水位、水质、补给开采条件、开发利用现状以及重要自然保护区、湿地、泉眼、易发生地质灾害等区域基础资料;按照我国《地下水功能区划技术大纲》划分原则,将研究区划分成为三个一级功能区,利用Arc GIS空间分析功能将相应二级功能区划指标数据空间化,进行叠置分析,突出地下水主导功能确定阈值,划分二级功能区边界,并绘制出地下水功能区划图实现其可视化;相关研究结果可为政府及相关部门提供开发利用地下水资源意见及措施。
Based on the unit boundaries of hydrogeology in Jilin Province, the groundwater types, water-rich degree, water level, water quality, supply and recovery conditions, development and utilization of groundwater in all administrative districts and counties, and basic regional basics of important natural reserves, wetlands, springs and geological disasters are reviewed According to the principle of division of groundwater function zoning technical outline in our country, the research area is divided into three first-level functional areas, and the corresponding second-level functional zoning index data is spatialized by ArcGIS spatial analysis function, and the overlay analysis is conducted to highlight the groundwater Dominant functions to determine the threshold, the division of the second functional area boundaries, and draw the groundwater function zoning map to achieve its visualization; related research results for the government and relevant departments to provide advice on the development and utilization of groundwater resources and measures.
