摘要
根据山东省植被特点,将植被分为农作物、乔木林、灌丛、草原和草甸、沼泽湿生植物五种主要类型,研究了不同植被类型的土壤重金属环境容量。结果表明:农作物的Cu、Zn、Pb、Cd的静态环境容量和动态环境容量均最小;不同植被类型土壤的平均动态年容量是土壤的静态年容量的7～20倍。
According to the characteristics of vegetation in Shandong Province, vegetation was divided into five main types ：crop, tree, shrub, grassland, meadow and marsh plant, and environmental capacity of heavy metals in soils of different vegetative types were studied. The results showed that both of the static and dynamic capacity of Cu, Zn, Pb, Cd in soils of crops were the lowest, the average dynamic capacity in soils of different vegetative types was7-20 times of the static capacity.
