摘　　要：变异函数作为地质统计学的核心内容和基本方法,可较好的反映分析矿床区域化变量基本特征,尤其是能反映地质变量的随机性和结构性的变化性。本章通过对区域化变量和变异函数及其功能的介绍,以DIMINE矿业软件为操作平台,对云南元江大明槽铜矿的实际勘探数据进行了统计分析、试验变异函数的计算以及理论变异函数的拟合,揭示大明槽铜矿矿体的矿化特征,分析矿体基本的空间变化规律,为矿床储量估算以及进一步的生产勘探、合理开发工作提供重要的理论依据。The variation function as the core content and basic analyse method of geostatistics,it can well research the basic characteristics of the regionalized varibles of a deposit.Especially,it can preferably reflect the randomicity change and spatial changeability of the variables.Through the introduction of regionalized variables and the variation function theory,the practical data of certain metal has been explained in this paper,based on the DIMINE software.While the experiment variogram calculation and theory variogram combination of the Damingcao copper has been showed.The variogram model indicates the mineral characteristics and the spatial changeability of orebody.The research may provide a significant basis for reserves calculation,exploration and rational exploration of mineral resources.
