摘　　要：在地理信息系统支持下,通过选择合理的分析模型,结合尹地金矿区的成矿地质背景和地球化学特征,以MAPGIS为技术平台,应用规则格网模型及对未采样地区的金元素化探数据赋零等方法对化探异常数据处理与分析,展示金矿区地球化学(异常)场的空间分布结构特征,自动圈定云南元谋尹地金矿区不同级次的找矿靶区,预测矿区金矿规律,为下一步找矿方案提供科学依据。The character of spatial distributing structure in unusual area for golden chemical date from Yindi gold mine district in Yunnan of China is represented, and the prospecting targets with different levels of the gold zone are automatically determined, and the gold mine deposit feature on geological prospecting is described, by using method such as formula grid model and endowing 0 to aurum data to deal with, under the support of GIS, comprehensively considering the geological base and the geochemical character of the district, with MAPGIS as the technique terrace. The results can be a scientific basis reference for future prospecting.
