中文摘要：

证据权模型通常使用二值数据,在把连续数据转化成二值数据时会损失有用信息。从贝叶斯原理角度提出了GIS矿产资源评价中统一使用连续和离散数据证据权法扩展模型的原理和方法,指出证据权模型中的证据权应为证据权函数,矿产资源评价中离散数据证据权函数为证据因子各可能取值的有矿和无矿条件概率比值对数,连续数据证据权函数为证据因子有矿和无矿条件概率密度函数比值对数。提出了用非参数估计条件概率密度函数和证据权函数方法,以及计算函数表和插值法简化运算的方法。以GIS云南铅锌矿产资源潜力评价为例进行了应用,并得到了较为理想的结果。

英文摘要：

The method of mineral potential mapping is generally based on weights of evidence model using binary maps, but the conversion from continuous data to binary data may lost important information as some data are Continuous variables. The paper proposes a new extended weight of evidence model using both continuous data and discrete data, and introduces its application in the Pb-Zn mineral potential mapping in Yunnan Province, China, with the untilization of 9 continuous data and 3 binary data maps of evidence. The application of this method in the area turns out satisfying result.
