摘　　要：主要阐述了高寒草甸景观区金的表生地球化学特征，以及制约金的表生地球化学异常发育的表生景观因素。研究表明，在对区域化探异常评价时，应将它与所处的地质、表生地球化学环境作为一个整体看待，将有利的环境标志转化为异常的评价指标，提高金矿勘查水平和找矿效率。The supergene geochemical features and the factors which control the supergene geochemical anomaly of gold in alpine meadow landscape are stated. The study reveals that regional geochemical prospecting anomaly should be considered with its geologic setting and supergene geochemical environment when we evaluate it.And favorable environment signs should be transformed into evaluation indexes of anomaly. This will be beneficial to improving the level of gold ore geochemical exploration and promoting prospecting efficiency.
