摘要:根据作者的研究和文献资料系统分析了我国杉木的能量利用、分配及生物生产力的特征和规律,结果表明:杉木不同器官的热值差异明显,平均为19.951kJg-1。生物量与密度和年龄呈较好的线性相关。不同地带、生长阶段、海拔高度的杉木光能利用率、能量的分配格局和林分生物量生产率不同;杉木的光合能量利用随不同林龄、密度和立地质量的不同而呈现光补偿点、光饱和点、CO2补偿点等的不同。总体上,我国杉木林对太阳总辐射和光合有效辐射的现实平均利用率分别为0.38%和0.81%,且由大到小依次为中带、南带、北带的规律;叶净光合生产率、生物量生产率、材积生产率也依次为中带、南带、北带,并与林分叶面积指数正相关。我国杉木人工林的培育仍具有很大潜力。
A comprehensive study on the energy use efficiency,pattern of energy balance and the productivity of Cunninghamia lanceolata was conducted.Different photosynthetic characteristics in the stands with different ages,densities and site qualities were shown , and the pattern of energy distribution,use efficiency and productivity are different in different regions,evaluation and stages of the tree growth.The present energy use efficiency for the total solar radiation income and photosynthetic active radiation is 0.38% and 0.81% respectively,and generally speaking,the value in the middle region is higher than that in the south,and that in the south is higher than that in the north region of the distribution areas of C.lanceolata. The net photosynthetic production of the leaf,the biomass and the growing stock is of the same feature,which is in direct proportion with the leaf are a index.A great potential is waiting for more rational cultivation.
