三清山主要树种重金属污染与华东各山的比较

对江西三清山常见树木叶片重金属含量进行分析测定，并与黄山、庐山、西天目山、乌岩岭同种树种进行了比较。结果表明：三清山已受到一定程度的污染，树木叶片对重金属具有富集作用，富集特性比较：铅：苦槠〉樟〉木荷〉青岗；铜：苦槠〉甜槠〉樟〉木荷〉青岗；镉：甜槠〉樟〉木荷〉苦槠〉青岗；锌：青岗〉甜槠〉苦槠〉樟〉木荷，４种重金属富集能力比较为镉〉铜〉锌〉铅。

COMPARISION OF HEAVY-METAL POLUTION OF COMMON TREES IN SANQINGSHAN MOUNTAIN WITH OTHER MOUNTAINS IN EAST CHINA

eavey metal contents in blade of common trees in Sanqingshan of Jiangxi were determined, and compared with that the same trees in Huangshan. Lushan, Xitianmushan and Wuyanling. Results show that trees in Sanqingshan have been polluted to a certain degree. Enrichment charactehstic of blade of tree for heavy metal are:Ph: Castanopsis sclerophylla > Cinnamomun camphora>Schima superba>Cyclobolonopsis glauca ; Cu: C. sclero phylla>Castanopsis eyrei> C, camphoar> S. superba>C, slauca; Cd: C. eyrei >C. camphora>S. superba >C.sclerophylla>c. glauca ; Zn: C. glauca>C. eyrei >C. sclerophylla>C. camphora>S. superba. The enrichmental capacity of four heavy metals: Cd>Cu>Zn>Pb.
