MAPGIS化探图数据网格化方法选择探讨

摘要

According to Cu surface soil samples for chemical analysis data which is from Urumqi – Changji in the project Of Multi-target Area in Xinjiang Uygur Autonomous Region Geochemical Survey,and using GRD Model in MAPGIS to generate geochemical anomaly map,the paper provides basis for prospecting, environmental geochemistry quality analysis.%根据新疆维吾尔自治区多目标区域地球化学调查（1：25万项目 GZTR20070117）中昌吉部分区域的地球化学土壤表层样Cu化学分析数据，利用MAPGIS软件中的GRD模型生成化探异常图，为找矿、环境地球化学质量分析提供依据。
