摘要:
以成都天台山及其周边区域马尾松、柳杉、杉木林为研究对象，通过野外调查、室内测试分析，开展了针叶林岩—土—植系统中毒害元素赋存规律研究，结果表明：3种针叶林立地As，Hg元素岩石库风化对土壤地质潜在输入次序为杉木林地、马尾松林地、柳杉林地；5种毒害元素中As，Hg，Cd，Pb4种元素均表现出在土壤表层有累积态势；而As元素在马尾松、柳杉等植物体运移能力强；Hg元素在杉木体内容易迁移；Al元素在杉木、柳杉内部的运输能力高；Pb元素在柳杉、马尾松中有较高的迁移能力；Cd在马尾松内容易发生转移；3种针叶树种对Pb，Hg，Cd的赋存能力高，而对Al，As两种元素的赋存能力较低。
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.
