摘要
采用分层切割法对不同年龄马尾松人工林的生物量进行研究。根据各径级标准木生物量建立回归方程,估算不同年龄马尾松林分各器官生物量。同时还比较了不同年龄林分生物量结构和生产力。马尾松林的生物量随着年龄的增大而增大。
The biomass of Pinus massoniana plantations with different ages was studied by adopting the layering and cutting method According to the sample tree biomass of various diameter classes,the regression equation was set up and the biomass of various organs of P.massoniana stands with different ages was estimated Meanwhile the biomass structure and productivity of the stands with different ages were also compared.The biomass of P.massoniana plantations increased with the increase of their ages and their net productivity assumed the parabolic status with the increase of their ages.
