摘要

摘要: 区域矿产资源潜力有总合式评价和非总合式评价两大类方法.总合式评价方法简便易行，可以得到一个区域的资源潜力总量的估计，但是没有其在区域中的空间位置信息，区域矿产资源潜力评价早期主要是用总合式评价方法.随着资料数据的积累，特别是计算机和GIS技术的应用，能给出空间位置信息的非总合式评价越来越多的用于区域矿产资源潜力评价.非总合式评价主要把区域划分成同形等大的单元，在圈定成矿远景区单元基础上，用类比方法对成矿远景区单元进行矿产资源潜力数量预测评价.总合式矿产资源潜力评价是区域矿产资源潜力评价的主要方法，可以对区域内潜在的矿产资源量进行预测，但是只有一个总量，没有区域内矿产资源空间分布信息，不能结合各局部空间具体情况进行各种环境经济社会评价，因此需要将其预测的资源量空间定位化.非总合式矿产资源潜力评价虽然能够定位，但因其是用控制单元的探明资源量进行类比外推，所以无法对已知矿产资源量的单元内潜在的矿产资源量进行预测.提出了用基于网格单元的总合式和非总合式方法结合的矿产资源潜力评价方法，解决了总合式方法单元资源量预测值的空间定位和分配问题.并且以云南铅锌矿为例进行了计算，既得到了总量也得到了其空间分布量，修正了非总合式预测方法的不足，特别适用于对矿产资源进行环境、经济、社会等评价或者联合评价.以云南铅锌矿产资源潜力评价为实例进行了应用，得到初步结果.

Abstract: There are two types of assessment methods of area mineral resources: aggregated form assessment and disaggregated form assessment. In aggregated form assessment, it is easy to get assessment of total mineral resources quantity of an area without high level data, but it is void of the message of spatial location of mineral resources, which is necessary to some co-assessments of resources, economy, environment and society. In disaggregated form assessment, work area is firstly divided into same shape grid units and then the mineralization favorableness unit and the mineral resources of unknown units are predicted analogically with known ore bearing units data, but potential resources number of known ore bearing units can not be obtained. So the paper presents a new method assessment of area mineral resources potential combining grid-units-based aggregated form with disaggregated form, in which the disaggregated form assessment number is modified by the information of aggregated form assessment, and at same time the aggregated form assessment result resources are located with the information of disaggregated form assessment. In the paper the method is used to assess Pb-Zn mineral potential of Yunnan Province and gets satisfactary results. The new method is particularly useful to GIS-based co-assessment of resources, economy, environment and society.
