摘要:
摘要 在雷州市附城镇岚北人工生态恢复的7 a生无瓣海桑群落生物量调查的基础上,对所采集的无瓣海桑进行了植物体各组分样品的灰分和元素含量测定与循环分析,结果表明:无瓣海桑植物体不同组分的灰分含量范围为2.27% ~26.41%,以细根的含量最高,枯枝的含量最低.植物体各组分中7种元素质量分数范围分别为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,Cu 0.16×10-5~1.50×10-5.其加权平均的富集系数为0.05~9.70,其中Ca>K>Cu>Na>Mg>Zn>Fe.群落现存生物量中的累积储量分别为K 109.76 g m-2,Ca 138.89 g m-2,Na 86.57 g m-2,Mg 81.07 g m-2,Fe 13.139 g m-2,Zn 0.483 g m-2,Cu 0.108 g m-2.群落2001年的元素存留累积储量分别为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,Cu 0.039 g m-2.2001年归还量分别为Ca 28.59 g m-2,K 16.83 g m-2,Mg 12.07 g m-2,Na 11.58 g m-2,Fe 0.916 g m-2,Zn 0.141 g m-2,Cu 0.026 g m-2.年吸收量分别为Ca 70.27 g m-2,K 54.07 g m-2,Mg 39.40 g m-2,Na 37.14 g m-2,Fe 5.191 g m-2,Zn 0.329 g m-2,Cu 0.065 g m-2.周转期分别为Zn 3 a,Cu 4 a,Ca 5 a,K 7 a,Mg 7 a,Na 8 a,Fe 14 a.与我国其它种类红树林比较表明,无瓣海桑群落在7 a的生态恢复过程中表现出对各测定元素吸收较快、周转期较短的特点. 图1表9参30
Abstract:
Abstract 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
