摘要：本文利用Monis分层切割法,对平均年龄为20年的木榄林不同径阶立木地上部分进行生物量测定,并按立木平均营养面积测定地下部分生物量。用相关生长测定法和平均木法换算成全林和立木各器官的生物量。测定了叶面积,并算出叶面积指数,用以评定林分生产力。分析了木榄的平均和连年净生产量的年动态变化以及净同化率随年龄的变化趋势。为合理经营和利用木榄林提供依据。
The paper deals with the biomass of average 20-aged Bruguiera gymnorrhiza stand. The vertical stratification method was adopted to measure the above ground biomass of different size-class trees in the stand. The tree mean growing area method was adopted for measuring the root biomass. The total biomass and the biomass of different tree organs within the stand were obtained by using both allometric method and the mean tree method. Besides, the leaf area of the stand was measured and the leaf area index was calculated so as to evaluate the productivity of the stand. In order to provide a theoretical basis for mangroves management and utilization, the yearly dynamic variation of the mean and annual net production and the variation tendency of the net assimilation rate with the increasing of the stand age have been analysed.
