生态定位观测结果表明,年平均干物质积累量、年每公顷材生长量、3年平均光能利用率皆以0.7经营密度为最高;林内凋落物的分解率随着经营密度的增加而减少,营养元素的归还量以0.7经营密度为最大。
The results of ecological location observation showed that annual average dry matter accumulation, annual biomass per hectare and annual 3-year average light energy utilization rate were the highest at 0.7. The decomposition rate of litter in forest decreased with the increase of operating density, The return of nutrients to 0.7 operating density is the largest.
