摘要:
于1994年3月,采用样方法分析、探讨深圳福田自然保护区车公庙林区白骨壤红树林重金属Cu,Ph,Zn,Cd元素的累积及分布。结果表明:该林地表层土壤(0 – 3 cm深),Cu,Ph,Zn,Cd的含量分别为38.3,28.7,114.0,0.136×10-6,储量分别为5285.40,3960.60,15732.00,18.77 mg/m2。植物体各部位Cu,Pb,Zn,Cd含量范围分别为1.81 - 13.8,0.402 – 3.51,3.42 - 69.5,0.013 – 0.295×10-6对表层土壤加权平均富集系数为Cd>Zn>Cu>Pb。该群落Cu,Pb,Zn,Cd现存累积量分别为53.70,19.27,187.89,0.72 mg/m2;年净存留累积量分别为4063.91,1318.14,16358.62,60.21 μg/m2;林地残留物相应元素的储量分别为2091.18,1958.66,5046.60,19.30 μg/m2。该林区不同群落叶层Cu,Pb,Zn,Cd现存累积量为白骨壤林>桐花树林>秋茄林。

Abstract:
Use of the quadrat method in March, 1994, to study the accumulation and distribution of Cu, Pb, Zn and Cd in the Avicennia marina mangrove community in the Futian Mangrove Nature Ressreve in Shenzhen, China, showed that their contents in the forest soil (depth 0 – 30 cm) were 38.3, 28.7, 114.0 and 0.136×10-6; their storages were 5285.40, 3960.60, 15732.00 and 18.77 mg/m2 respectively; their contents in different plant parts were 1.81 - 1.38, 0.402 - 3.51, 3.42 - 69.5 and 0.013 - 0.295×10-6, and that their storages in the community were 53.70, 19.27, 187.89 and 0.72 mg/m2, respectively. The accumulation index of the plant in the soil was Cd > Zn > Cu > Pb. The annual net retention accumulation of Cu, Pb, Zn and Cd in the community were 4063.91, 1318.14, 16358.52 and 60.21 μg/m2 and their storages in the residues were 2091.18, 1958.66, 5046.60 and 19.30 μg/m2 respectively; and their pool amounts in leaves of various types of communities were in the order Avicennia marina > Aegiceras comicula tum > Kandelia candel.
