Abstract:: This paper studies the Pinus massoniana,Cryptomeria fortunei,and Cunninghamia lanceolata forests in and nearby Tiantai Mountain in Chengdu economic area.Through field survey and laboratory test,a study on occurrence regularity of poisonous elements in rock—soil—plant system of coniferous forest was carried out.The conclusions were drawn as follows:in the three kinds of coniferous forest sites,the potential input order of As,Hg from rock to soil by weathering is Cunninghamia lanceolata,Pinus massoniana,Cryptomeria fortunei;among five poisonous elements,four elements,As,Hg,Cd,Pb,have a accumulative trend in the soil surface;As has a strong migration ability in Pinus massoniana plants and Cryptomeria fortunei plants;Hg migrates easily in Cunninghamia lanceolata plants;Al migrates easily in Cunninghamia lanceolata plants and Cryptomeria fortunei plants;Pb migrates easily in Cryptomeria fortunei plants and Pinus massoniana plants;Cd migrates easily in Pinus massoniana plants;the three kinds of coniferous species have high ability on Pb,Hg,Cd occurrence,but low ability on Al,As occurrence.This paper has theoretical and practical significance on choosing plants with high poisonous elements remediation and enrichment ability,on finding out the geochemical background,on guiding agriculture and forestry production.
