土壤质量地球化学分级算法研究与实现

Study and implementation of geochemical grading algorithm of land quality

土壤质量地球化学分级工作一直由人工完成,操作繁琐、耗时费力,出图周期较长。通过对分级标准进行归纳整理,得到标准字典,设计出一套自动分级算法以自动获取其质量等级,根据赋色标准进行可视化并存储到本地,基于MapGIS平台二次开发,设计了一套批量化、一键式的自动分级工具,大大简化了工作流程,提高了土壤质量地球化学分级工作效率。

The geochemical grading of land quality has been done manually, which is tedious, time-consuming and labor-intensivewith long drawing circle. The paper categorizes the grading standards and obtains a standard dictionary. An automatic grading algorithmis designed to automatically obtain the quality grade. The result is visualized according to the coloring standards and stored locally.Based on the secondary development of the MapGIS platform, the large-volume, one-touch automatic grading tool greatly simplifies theworkflow and improves the efficiency of geochemical grading of land quality.
