中文摘要：调查研究了雷州的无瓣海桑 (Sonneratiaapetala)林分地上部分和地下部分生物量和生产力 ,结果表明无瓣海桑单株立木和林分的生物量均随林龄的增加而增加。 6 .5年生的无瓣海桑单株立木和林分生物量分别为 88.16 8kg/株和 116 .914kg/m2 ;林分的生物量及各器官组分的分配 ,大小排序为干材 >树枝 >树根 >树叶 >树皮 >花果 ;干材的林分生产力随林龄增加而增加 ,其他器官各年龄的林分生产力较稳定。根系的生物量随着林龄的增长而增加 ,但水平生长比垂直生长快 。

外文摘要：The biomass and productivity were investigated on the artificial stands of Sonneratia apetala. The results showed that the biomass of single tree and stand of it increased with the increase of the stand age. They were 88.168 kg/tree and 116.914 kg/m 2 in the stand of Sonneratia apetala of 6.5 years respectively. The biomass and its distribution of tissues were in the order of stem>branch>root>leaf>bark>flower and fruit. The productivity of the stem increased with the increase of the stand age. Other tissues' productivity was steady. The increment of root biomass increased with the stand age. In this paper, a regression analysis is conducted on the correlationship among the biomass of the organs of Sonneratia apetala.
