摘要:

本文探讨了深圳福田红树林保护区56年生白骨壤群落的生物量、生长量及能量分布。结果表明:该群落现存生物量为16583.88g/m2,其中地上部占66.78%,地下部占33.22%。年增长量(1993)为1149.8g/m2。植物体各组分热值含量变化范围在16.1~18.22KJ/g,其中以树干材热值含量居最高,而中根最低;群落能量现存量为291839KJ/m2,其中地上部占68.51%,地下部占31.49%;群落年增长能量存留量(1993)为20213KJ/m2

Abstract:

A study was carried out on the biomass, increment and energy of mang rove communities which were dominated by Avicernia marina, and located in Shenzhen Bay, southern Chian.The research results showed that retained biomass was 16, 583.88 g/m2, for which aboveground and underground parts were accounted for 66.78 %and 33.22 %, respectively.Biomass increment of the communities in 1993 was 1, 149.8 g/m2, which was mainly distributed among stem (323.96 g/m2), twig (238. 33 g/m2), and perennial branches (213.06 g/m2).Caloric values of different plant fractions varied in a range of 16.1 ~ 18.22 kJ/g, however, the caloric value of stem wood was ranked on the top and that of mid-root on the bottom.The existing energy for the communities was 291, 839 kJ/m2 for which 68.51 %and 31.49 %were partitioned into the above-and underground parts, annual energy accumulation in the communities was 20, 213 kJ/m2 in 1993.
