摘　　要：成都市是Hg的高背景和民异常区 ,深、浅层样各具不同的元素组合和发育特征。深层样Hg异常与构造、天然气、地热、矿产和基底隆起有关 ;浅层样则与城市居民生活 ,古代颜料、工业、燃煤、农业。Chengdu City lies in Hg-high background region and Hg-anomalous region. Surface and deep geochemical samples are different in element association. Hg anomalies from deep geochemical samples are related to structure, natural gas, geotherm, minerals and basement uplift,while Hg anomalies from surface geochemical samples are related to inhabitant life, ancient pigments,industry, agriculture, fluvial pollution and minerals upper reaches.
