Abstract
探讨了福建九龙江口桐花树红树林对Cu、PH、zn、Cd、Mn元素的吸收、累积及分布.结果表明:该林地土壤5种元素的储量关系为Mn>zn>PH>Cu≥Cd;植物体不同部位,各元素含量有着明显的差异,含量范围分别为CH1.51~5.70、Pb1.30~10.70、zn18.0~100.1、Cd0.04~0.23和Mn15.5~237.5(W/10-6);植物对土壤元素的富集系数大小依次为Cd>zn>Mn>Cu>PH;群落现存生物量中,Cu、Pb、zn、Cd、Mn元素的现存累积量分别为16.56、63.30、445.05、1.14和1656.93(ρA/Mg·M-2).其中,地下部分别占70.2%、81.8%、76.2%、72.2%和82.1%;林地残留物相应元素的储量分别为211.11、184.00、1941.69、6.19和22248.31(ρA/μg·M-2).
 
Aborption,accurnulation and dsribtit on of Cu, Pb, Zn , Cd and Mn elements in Aegiceras corniculatum mangrove Forest in the estuary of the Jiulong River in Fujian were studied and the results showed that the storages of those elements in the soil of the Forest were Mn > Zn > Pb > Cu ≥ Cd ; the element contents in diFFerent plant perts were quite diFFerent, the ranges of the contents were Cu 1.51  ̄5.70, Pb 1.30 ̄ 10.70,Zn 18.0 ̄ 100.1,Cd 0.04  ̄ 0.23 and Mn 15.5 ̄ 237.5(w/ 10-5 ),and their storages in the standing crops of the community were 46.56 For Cu, 63.30 For Pb, 445.05 For Zn, 1.14 For Cd and 1 656.93 For Mn ((),of which the underground pert accounted For 70.2%, 81.8%, 76.2%, 72.2% and 82.1 %, respectively ; the accumulation ratio of the elements in plants to those in soil was Cd>Zn>Mn>CU >Pb; the storages of elements in the litter on Forest Floor were Cu 211.11, Pb 184.00 , Zn 1941.69,Cd 6.19 and Mn 22 248.3 1 ( ), respectively.
