马尾松生物量和生产力研究进展

马尾松在我国南方亚热带地区广泛种植，是我国主要植树造林树种之一，长期以来产生了巨大的生态和经济效益，在我国林业中有着重要地位。在全球气候变暖这一大背景下，研究马尾松森林生态系统的生物量和生产力具有非常重要的意义。文中从传统方法和遥感技术2个方面介绍了马尾松生物量和生产力的测算方法，分析了林龄、混交造林、立地条件、气候因素和林分密度对马尾松生物量和生产力的影响，并针对目前存在的问题提出未来研究的发展方向，以期为我国马尾松林的可持续经营提供参考。

Researches Progress in Biomass and Productivity of Pinus massoniana

Pinus massoniana is widely planted in the subtropical region of South China, which is one of the main afforestation tree species in China. It has brought enormous ecological and economic benefits for a long time and has an important position in China''s forestry. Therefore, it is of great significance to study the biomass and productivity of P. massoniana under the background of global warming. This paper introduced the methods for measuring and calculating biomass and productivity of P. massoniana from two perspectives of traditional methods and remote sensing technology. The effects of stand age, mixed planting, site conditions, climatic factors and stand density on the biomass and productivity of P. massoniana were analyzed, and the development direction of future research was put forward against the current problems, in order to provide references for the sustainable management of P. massoniana forest in China.
