从林隙的形成方式、大小分布和形成木特征等几方面对缙云山森林林隙的形成特征进行了初步研究。结果表明 :缙云山森林林隙的形成方式以根拔、折干和枯立为主 ;林隙多由双形成木和三形成木形成 ,每个林隙平均形成木拥有量为 2 .88株 ;扩展林隙在 1 0 0~ 3 0 0m2 之间分布最多 ,冠空隙在 1 50m2 以下分布最多 ;扩展林隙直径与林隙高度比值“多分布在 0 6~ 1 4之间 ,冠空隙直径与林隙高度比值多分布在 0 2~ 0 8之间 ;林隙形成木以马尾松、四川山矾、四川大头茶、银木荷、黄杞和小叶栲为主 ,且其在径级达到 2 0~ 50cm、高度达到 1 5~2 5m时 ,最可能倒伏或枯立创建林隙 ;平均每株形成木所形成的扩展林隙面积为 76 8m2 ,形成的冠空隙面积为3 4 4m2 。
The formation characteristics of gaps in the forest gap of Jinyun Mountain were studied from the aspects of the formation of gap, the distribution of size and the formation of wood. The results showed that the forms of gap formation in forest in Jinyun Mountain were dominated by root drafting, dry - folding and dry litter. The gaps were mostly formed by bivalve and tricominate trees, with an average of 2.88 trees per gap. Most of the gaps were distributed between 1 0 0 ~ 300 m 2 and the crest below 1 50 m 2. The ratio of gap diameter to gap height was mostly distributed between 0 6 and 1 4, The ratios of gap height to gap height ranged from 0 2 to 0 8. The gap formation was dominated by Pinus massoniana, Sichuan asparagus, Sichuan dwarf tea, 0 ~ 50cm, height of 15 ~ 25m, most likely to lodging or withered to create gaps; the average formation of each formation of wood expansion gap area of 76 8m2, the formation of crown gap area of 34 4m2.
