查询词典 spruce

The results show that as the crown density reduces the foresttype diversity increases and as the diversity goes up the stability of stand comes down; that the forest is under regressive succession and its stability now is the lowest; that the growth of spruce and fir trees has obviously a n...

结果表明：该林区的林分类型多样性随郁闭度的降低而增加，林分的稳定性随多样性的增加而降低，林分处于逆向演替过程中，林分的稳定性处于最低限；云、冷杉林与环境因子——海拔之间呈明显的负相关；在高海拔区云、冷彬林十分脆弱，一旦原有种群结构的郁闭度低于0.3，森林的稳定性将被破坏，即使在完全封禁的条件下，25年生的疏林要恢复到有林地状态，需要40年的时间。
