对桂东丘陵区不同年龄马尾松林生物量进行了研究。结果表明,7年生松林的生物量为67.2t/hm~2,14年生林分为92.6t/hm~2,23年生林分为159.8t/hm~2,38年生林分为202.6t/hm~2。并对林分生产力进行了分析。该项研究可为制定疏伐措施和确定主伐年龄提供科学依据。
The biomass of Pinus massoniana forest at different ages in the hilly area of eastern Guangxi was studied. The results showed that the biomass of 7-year-old pine forest was 67.2t / hm -2, that of 14-year-old forest was 92.6t / hm -2, that of 23-year-old forest was 159.8t / hm -2, and that of 38-year-old forest was 202.6t / hm ~ 2. The productivity of the stands was analyzed. This study provides a scientific basis for the development of thinning measures and the determination of the dominant cutting age.
