英文摘要	探讨了广西英罗湾红海榄红树林重金属Cu、Pb、zn、Cd、Cr元素的累积及动态。结果表明：植物体不同部位元素的含量范围，分别为Cu0.433~1.21、Pb0.369~1.88、zn2.94~7.66、Cd0.020~0.233和Cr0.330~0.562ug/g。林地残留物组分元素含量远高于植物体及凋落物组分含量。该群落Cu、Pb、zn、Cd、Cr的现存储量，分别为28.73、25.25、143.68、3.14和14.61Mg/M2。林地残留物相应元素的储量，分别为271.68、323.41、1983.70、8.18和34.44ug/M2。群落Cu、Pb、zn、Cd、Cr元素的生物循环为：年吸收量分别为1351.70、1613.12、8808.37、240.74和759.30μg/M2；年存留量分别为842.46、806.91、4694.10、94.88和464.80μg/M2；年归还量分别为509.24、806.21、4114.27、145.86和294.50μg/M2；周转期分别为56、31、35、22和50年；流动系数Cd＞PH、zn＞Cu、Cr。; The accumulation and dynamic of heavy metal, Cu, Ph, Zn, Cd and Cr elements were studied in Rhizophora stylosa mangrove community at Yingluo Bay of Cuangxi, China.The results showed that: 1) In diFFerent parts of the plant the contents of the elements were: Cu 0.433～1.21, Pb 0.369～1.88, Zn 2.84～7.66, Cd 0.020～0.233 and Cr 0.330～0.562(ug/g).The contents of the elements in residues were much higher than those in the plant and litter Fall.2)The pool amounts of the elements in standing crop of the community were:Cu 28.73, Pb 25.25, Zn 143.68, Cd 3.14 and Cr 14.61(mg/m2).The pool amounts of the elements in residues were: Cu 271.68, Pb 323.41, Zn 1983.70,Cd 8.18 and Cr 34.44(g/m2).3) The biological cycles of the elements in the community were: Annual retention, Cu 1351.70, Pb 1613.12, Zn 8808.37, Cd 240.74 and Cr 759.30 (g/m2); Annual retention: Cu 843.46, Pb 806.921, Zn 4694.10, Cd 94.88 and Cr 464.80 (g/m2); Annual return Cu: 509.24, Pb 806.21, Zn 4114.27, Cd 145.86 and Cr 294.50 (g/m2).4) the turnover period was: Cu 56, Pb 31, Zn 35, Cd 22 and Cr 50 (a).The Flow coeFFicients were Cd>Pb and Zn>Cu and Cr.; 国家自然科学基金
