摘　　要：基于 MAPGIS系统平台空间分析方法的特点 ,以华南地区的锡多金属矿床为空间分析对象 ,对锡多金属矿床的分布态势及有利成矿地层、构造、岩浆岩等要素的相关对象属性进行了统计分析 ,初步总结出华南地区燕山期和晋宁期岩浆岩、泥盆系和侏罗系地层及 NE向或 NEE向断裂带等有利因素的叠加复合部位是寻找锡多金属矿床的有利成矿条件组合标志 。Based on the spatial analytical module of MAPGIS system, this paper tries to carry out the statistical analysis of a large regional spatial data, and statistically analyses some properties of the related objects including favorable ore-forming strata, structure, magmatic rock and the distribution trend of tin-polymetallic deposits in South China. Preliminary summarization of the favorable combination index for mineralization of tin polymetallic deposits, points out that the most favorable area for tin-polymetallic deposit is the crossing place with the magmatic rocks of Yanshanian and Jinningnian and the strata of Devonian and Jurassic plus NE or NEE tectonic structure. This paper finally provides sound evidence for metallogenic prediction and related geological survey and ore exploration disposition for ore deposits.
