| 摘 要： | 文章在广泛收集研究区已有地质、物探、化探、遥感等资料的基础上,基于GIS建立了湖南省地学空间数据库。通过对比分析多个不同成因类型金矿床的成矿条件,建立矿床统计学预测数学模型,选取四大类68个标志信息,利用DPIS系统(Deposit’s Position Indicating System)的信息量计算法,筛选出25个有用找矿地质标志,并计算出各标志对预测湖南省金矿的影响因子,最终圈定了研究区金成矿信息总量异常区,结合地质、矿产、化探等数据综合分析,进行金矿床定位预测。 |

| Abstract: | On basis of extensive collection of geology,geophysics,geochemistry and remote sensing data,GIS geo-spatial database and statistical prediction model were established by comparing a number of different genetic gold deposits.From sixty-eight symbols selected,twenty-five symbols were proved to be useful by function of calculation information of DPIS system,also factors of symbols for predicting gold deposits were calculated.At last,information anomaly areas were drawn,and prediction work was successfully done according to geology,resources and geochemical data. |
| Keywords: | Hunan Province gold deposit DPIS system methods of calculation information position prediction |
