摘　　要：协同克立格法是多元地质统计学的主要方法，该法能充分利用多元信息，有效地提高块段（块体）平均品位及矿产储量估计的精度。介绍了协同区域化理论和协同克立格法及其在我国某优质锰矿床储量计算的实例。okrigihg is a principal method of multivariate geostatistios Cokriging make full use of the multivariate information for ef-fective improve estimation precision of average grade and mineral reserves of the block(or the deposit).In this paper,the theoryof coregionalization and cokriging are described.the ease of apply cokriging to estimation of mineral reserves of high-grademanganese deposit in China is presented in more detail,which involve four part:Statisticl analysis of coregionalized variables;Calculation of crossvariogram and cross-covariance and structure analysis;Cokriging estirnation of average grade of blcoks;Esti-mation of ore reserves of deposit,and compared result obtained by cokriging with by other rnethods.
