研究了辽东栎(Quercus liaotungensis)林生物量、能量分配和能量密度过程,结果表明,辽东栎林的生物量在60~200 t·hm-2之间,乔木层的生物量在50~160 t·hm-2之间,在林分中所占比例为80%~98%,辽东栎生物量在林分中所占比例从40%到100%,净初级生产力从, 5 t·hm-2·a-1到24 t·hm-2·a-1。辽东栎群落能量现存密度为83000 kcal·m-2,其中乔木层占96.65%、灌木层占3.12%、草本层占0.23%。乔木层中各器官能量密度排列顺序是树干> 树根> 树枝> 树叶,比例是4:3:2:1,灌木层中,各器官能量密度顺序是干> 枝> 根> 叶。最后给出了该类森林生态系统变化的生物量和能量概念模式,为下一步建立抽象的数学模型,建立可操作能实用的计算机模拟模型打下了基础。
The biomass and energy partitioning in the warm temperate deciduous broad-leaved forest were analyzed. The partition of biomass and energy in oak forest ecosystems showed that the dominant tree species oak accounts for the biggest percentage in the forest. The biomass of oak forest was 60-200 t·hm-2, tree layer 50-160 t·hm-2. The percentage of tree layer biomass in community was 80%-90%, the percentage of oak biomass is 40%-100%. The forest net primary production was 5-24 t·hm-2. The standing total energy value of the oak community was 83000 kcal·m-2. The tree layer accounted for 96.65%, shrub layer 3.12%, and herb layer 0.23%. The energy density orders at different organs of tree layer were stem, root, branch and leaf, and the ratio was in 4:3:2:1. Shrub layer orders were stem, branch, root and leaf. After the biomass and energy density were analyzed, the concept model was developed for biomass and energy. The concept model would be the basis for abstracted mathematical and computer models will be established.
