| 摘 要： | 本研究测定了广西龙门岛群桐花树天然林地上部分的生物量。按径阶标准木法分别调查了3种不同年龄阶段天然林的群落生物量，根据18株不同径阶标准木的测定数据，建立了估测群落单株林木地上部各器官生物量的回归方程，方程的相关系数均达极显著水平，估测精度较高，具有实用价值。研究的结果表明，5年、l7年和20年生的桐花树群落地上部生物量分别为3743.5g／m2、7279.0g／m2和8817.1g／m2，年均生产量分别为748.7g／m2·a、428.2g／m2·a和440.9g／m2·a。

| Abstract: | The aboveground biomass of Aegiceras corniculatum (L.) Blanco natural forest in Longmen islets of Guangxi was determined in the paper. The aboveground biomass of three natural stands at different ages were investigated with the average standard tree method. According to the data from 18 standard trees of different basal diameter classes, the following regression equations to estimate the biomass of each aboveground organs of A. corniculatum were described from single plant:With significant correlation coefficients, the equations had practical values. The results obtained showed that: (1) The above-ground biomass in 5, 17 and 20-year-old A. corniculatum stands were 743.5g/m2, 7279.0g/m2 and 8817.1 g/m2 respestively. (2) The average productivity were 748.Tg/m2·a,428.2g/m2·a and 440.9g/m2·a respectively. |
