| 摘 要： | 依据生物地球化学循环理论构建了林业生态地球化学预警模型,并以成都经济区生态屏障体系建设中成功营建的主要人工桤木林为例,通过对林地土壤母岩、土壤、活植物体和枯落物中五种地球化学污染元素含量的测试分析,进行了生态地球化学预警模拟.模拟结果表明,人工桤木林对土壤污染元素As,Hg,Pb,A1,Cd的修复能力较强,尤其是对Cd元素的修复,仅需3年左右的时间可使受污土壤达到净化状态.

| Abstract: | Based on the biological geochemical theory,a warning model of forest ecological geochemistry is constructed.Through the analysis of soil rock,soil,plants and litters,the simulated warning test of alder forest ecological geochemistry is made,and the results show that phytore mediation of alder plantation for pollution elements(As,Hg, Pb,Al,Cd) is relatively good,of which the remending time for Cd is about three years.The above results also show that the constructed warning model is scientific and adaptable and suitable for prediction and assessment of forest ecological geochemistry. |
