| 中文摘要: |
| 讨论了地质统计学（空间信息统计学）在固体矿产资源／储量分类中的若干问题，主要包括：1）矿产资源／储量估计方法的选择；2）两个重要概念－估计方差及离差方差；3）支持效应及其在矿产资源／储量评估中的重要作用；4）特异值（特高品位）的识别及处理方法；5）关于吨位－品位曲线；6）确定最优勘探网度及取样间距（及位置）的地质统计学方法；7）地质统计学在确定最优矿床工业指标中的应用；8）储量计算及固体矿产资源／储量分类的地质统计学实施方案。 |
| 英文摘要: |
| This paper studied some problems of application of geostatistics (spatial information statistics) in classification for resources/reserves of solid fuels and mineral commodities. The paper has dealt mainly with eight questions; 1) Choise of estionation methods for mineral resources/reserves; 2) Two important concepts: estimation variance and dispersion variance; 3) support effect and its important role in appraisal of mineral resources/reserves; 4) Identification and handling of outliers (very high-grade); 5) about reserve tonnage-grade curve; 6) Geostatistical methods for define optimum density of propecting net and sample inteval; 7) Use of geostatistics to define optimum industrial inder of ore deposit; 8) Geostatistical carry out programme to calculate reserves and classification for resources/reserves of solid fuels and mineral commodities. |
