外文摘要：Based on the former biomass survey results of the seven-aged restored Sonneratia apetala community in Lanbei, Fuchen, Leizhou, the results from the analysis on ash and elemental contents of the S. apetala samples collected from the survey showed that the ash contents of different parts of S. apetala were between 2.27%～26.41%, with the highest in fine root and the lowest in dead branch. The elemental mass fraction in different partitions of S. apetala as K 0.11%～1.56%, Na 0.11%～1.66%, Ca 0.20%～2.66%, Mg 0.15%～1.59%, Fe 0.04×10 -3～9.64×10 -3, Zn 0.05×10 -4～1.03×10 -4 and Cu 0.16×10 -5～1.50×10 -5. The average elemental accumulation ratios by the plant dry weight were between 0.05～9.70 in order as Ca>K>Cu>Na>Mg>Zn>Fe. The total amount of elements stored in the community's standing biomass were K 109.76 g m -2,Na 86.57 g m -2,Ca 138.89 g m -2,Mg 81.07 g m -2,Fe 13.139 g m -2,Zn 0.483 g m -2 and Cu 0.108 g m -2. The total yearly accumulation amount of elements of the community in 2001 were Ca 41.68 g/m -2,K 37.24 g m -2,Mg 27.33 g m -2,Na 25.56 g m -2,Fe 4.275 g m -2,Zn 0.188 g m -2 and Cu 0.039 g m -2;Yearly total return amount in 2001 were K 16.83 g m -2, Na 11.58 g m -2, Ca 28.59 g m -2, Mg 12.07 g m -2, Fe 0.916 g m -2, Zn 0.141 g m -2, and Cu 0.026 g m -2; Yearly total absorbing amount were K 54.07 g m -2,Na 37.14 g m -2,Ca 70.27 g m -2,Mg 39.40 g m -2,Fe 5.191 g m -2,Zn 0.329 g m -2 and Cu 0.065 g m -2. The elemental circulatory periods of K was 7 years Na 8 years, Ca 5 years, Mg 7 years, Fe 14 years, Zn 3 years, and Cu 4 years. During its short 7 year period of restoration process, the community showed high absorbing and circulatory speed of the tested elements compared with other mangroves in China. Fig 1, Tab 9, Ref 30
