摘　　要：G IS空间分析是成矿预测的一个重要手段,而其利用的数学模型是成矿预测成败的关键之一。介绍了不同数学模型的优缺点,探讨了不同数学模型的适用条件及范围。以扬子地台冕宁—盐源—西昌一带为例,分析了控矿因素,利用G IS空间分析等方法,在代数法支持下,对成矿区进行了预测,圈定了远景区,为进一步找矿提供了一种新的途径。Spatial analysis has become an important means in the prediction of mineral resources and the application of mathematic model is the key for the success of metallogenic prediction. The authors depict the merits and disadvantages of the model, discuss the applicable conditions and scopes of the model . Taking Mianning-Yanyuan-Xichang region within Yangzi Platform as an example, the authors analyze the ore-control factors, with the help of GIS spatial analyses and algebra, predict the metallogenic zones, delineate the ore prospects and provide a new channel of prospecting the minerals.
