摘 要: | EGCLTH仿真系统是我们新近研制成功的一种非线性化探数据处理与成图系统,它可以在计算机上实现从低密度的采样数据得到高密度的地球化学勘查结果,特别是从1:20万化探扫面数据模拟得到符合1:5万地球化学实测要求的点位的元素含量数据和地球化学图,从而或许可以不再需要通过单点样分析或面积性采样来进行1:5万地球化学填图。以著名勘查地球化学家、中国科学院院士谢学锦教授等专家组成的鉴定委员会确认:EGCLTH系统是一项首创性的具有国际领先水平的新技术,它不仅在地球化学填图、勘探网度模拟、矿产储量计算、环境…

Abstract: | The authors first develop a simulating system-EGCLTH having application in geochemical mapping. It is a nonlinear data processing and graphic systen. Using EGCLTH system high den- sity geochemical measuring results can be achieved automatically from low density sampling data. For example, we have constructed the geochemical maps of China corresponding to a sampling density of 1 sample/6400 km2 from the data of 529 samples, nearly covering the whole land surface of China, rpovided by Xie Xuejin (1995). Global Sampling Committee, International Geochemical Mapping Project is taking a lpan in which the world's land surface will be covered with 5000-6000 smaples. EGCLTH system will make quickly it possible to construct an Asia and World Geochemical Atlas from the data of these samples. |
