摘　　要：在对中国 5个重要景观区 1∶2 0万金、铜表生地球化学异常特征进行总结、对比 ,并讨论景观、表生因素对区域异常评价标志影响的基础上 ,进一步充实、完善了区域异常系统评价体系的思路和评价准则 。This paper persents one of the achievements of the project 'The study of the characteristics of epigenetic geochemical anomalies and the evaluating system for major landscapes of China'. It has summarized the characteristics of epigenetic gold and copper geochemical anomalies (1∶200000) in five major landscapes of China and discussed the effect of landscape ies. On such a basis, the evaluating method and the systematic evaluating criteria for regional anomalies are further substantiated and improved, and the quantitative model for systematic evaluation of regional geochemical anomalies are established.
