中文摘要：无瓣海桑作为潮间带红树林外来树种,在有长年淡水排放条件的中高潮间带红树林生态恢复生境中具有优良速生特点。2001年5月对雷州半岛附城岚北的6年生无瓣海桑人工林进行了调查,林地样地和标准木调查结果显示,该人工林年平均树高生长为2.03 m,年平均胸径生长为2.35 cm;地径与胸径呈极显著相关性。标准木单株总生物量干重为95.647 kg,群落单位面积生物量为22.955 kg/m2;地上生物量与地下生物量之比为1.60;当年平均生物量积累为9.337 kg/m2;单株材积为88.23 dm3、当年材积的年生产力(PA)为0.407。群落单位面积热能积累为424.851×103 kJ,年太阳辐射能固定成生物量的转换率为40.68 ×10-7%。结果表明无瓣海桑在红树林树种中具有突出的高生物量生长积累特性,应作为我国南方海岸滩涂的优良速生造林树种加以推广。

外文摘要：The exotic Sonneratia apetala in Leizhou Peninsula, has shown outstanding fast-growing ability in restored mangrove forests, at the middle and high tide intertidal zone, with year-round fresh water input from drainage. By setting plot and selecting standard tree, investigation and measurement on height growth, diameter growth, biomass, productivity, and so on, were made in a S. apetala plantation at age of six at Lanbei, Fucheng, Leizhou Peninsula in May 2001. The investigating results showed that the mean annual height growth of plantation was 2.03 m and mean annual growth of diameter at breast height (DBH) was 2.35 cm. There exists a significant correlation between the diameter at ground surface (DGS) and DBH. The average biomass of a single standard tree in dry weight was 95.647 kg/m2. A ratio of above-ground biomass to under-ground biomass was 1.60. The stand biomass of unit area was 22.955 kg/m2, singletree wood volume was 88.23 dm3, and the annual wood volume productivity (PA) of the same year was 0.407. The forest energy accumulation was 424.851 MJ/m2, with annual solar energy fixing rate of 40.68 ×10-7%. It is concluded that S. apetala species had characteristics of outstanding high biomass accumulation and could be used as coastal planting tree species in southern China.
