摘要
利用１：２０万地球化学勘查数据，编制小比例尺地球化学图，全国业已开展。经制图方法试验研究，本文提出了化探数据分析偏倚均值校正法，提出了１：５０万等值线地球化学图编制方法技术，试验完成了１：５０万和１：１５０万等值线地球化学图集。
The compilation of small-scale geochemical maps by using 1:200000 geochemical exploration data has been carried out in the whole country. Based on experimental study of the mapmaking method,the present paper has put forward the mean correction method for deviation in geochemical data analysis,and advanced the method and technique for compilation of the 1:500000 geochemical contour map. The first 1:500000 geochemical contour map of China and 1:1500000 geochemical contour atlas have been completed on the trial basis.
