摘要
详细介绍阿尔泰成矿区金矿预测图形库及属性库的建立原则及方法 ,尤其是图层划分的一般原则、属性结构建立及属性分类方法。图层划分应依据研究中所形成的认识和矿产预测信息处理的需要 ,便于输入调用和分析 ,同一类图元、属性结构一致的图元尽可能放到同一图层。最后给出了阿尔泰成矿区图形库和属性库的具体内容。
This paper introduces building method of database of diagram and attribute of gold ore predictive for metallogenic region of Aertai Xinjiang,China,especially introducing general principle of dividing diagram layer and attribute structure and attribute category. That is, dividing diagram layer must be base on realizing formed in exprience and demanding of information processing of ore predictive, the second, it is convinient for input as well as use and analysis, the third, diagram layer of same class diagram layer and same attribute must be played together. At end, this paper gives specific context of database of diagram and attribute gold ore predictive for metallogenic region of Aertai area Xinjiang, China.
