ArcGIS绘制地下水埋深变幅分区及计算蓄变量的应用
Application of ArcGIS in Drawing Groundwater Depth Variation Zones and Calculating Storage Variables

采用地下水监测站埋深年变幅数据，使用ArcGIS 10.8，生成地下水监测站点图层，使用“克里金差值分析”方法，绘制地下水埋深年变幅等值线、变幅分区，变幅分区、县、给水度分区叠加相交，通过字段计算器，使用“水位(埋深)变幅法”，计算单元图斑的地下水蓄变量。表述ArcGIS 10.8绘制变幅等值线、变幅分区、相交、字段计算器、计算蓄变量等方法及详细操作步骤。
ArcGIS 10.8 was used to generate groundwater monitoring site layers based on the annual variation data of groundwater monitoring stations. The “Kriging difference analysis” method was used to draw the annual variation contour of groundwater depth, variation zone, variation zone, county and water supply degree zones superposed and intersecting. The “water level (buried depth) variation method” was used through field computer. Calculate the groundwater storage variable of the cell plot. The methods and detailed operation steps of ArcGIS 10.8, such as drawing variable contour, variable partition, intersection, field calculator and calculating variable storage, are described.
