选择西藏色季拉山急尖长苞冷杉天然林为研究对象,在海拔梯度上以群丛作为评价的基本单位,进行冷杉群落结构健康评价。对群落物种多样性和群落结构特征因子,采用主成分分析,筛选主要评价指标,结合层次分析法( AHP法)进行健康排序。结果表明,对冷杉林群落结构健康影响最大的因子依次为:年龄结构、灌木层盖度、乔木株数、更新数量、草本种类、郁闭度、草本层盖度、灌木种类、乔木种类和亚层数共10个因子。健康排序次序为急尖长苞冷杉-林芝云杉群丛、急尖长苞冷杉+忍冬群丛、急尖长苞冷杉+杜鹃群丛、急尖长苞冷杉+苔藓群丛。
選擇西藏色季拉山急尖長苞冷杉天然林為研究對象,在海拔梯度上以群叢作為評價的基本單位,進行冷杉群落結構健康評價。對群落物種多樣性和群落結構特徵因子,採用主成分分析,篩選主要評價指標,結閤層次分析法( AHP法)進行健康排序。結果錶明,對冷杉林群落結構健康影響最大的因子依次為:年齡結構、灌木層蓋度、喬木株數、更新數量、草本種類、鬱閉度、草本層蓋度、灌木種類、喬木種類和亞層數共10箇因子。健康排序次序為急尖長苞冷杉-林芝雲杉群叢、急尖長苞冷杉+忍鼕群叢、急尖長苞冷杉+杜鵑群叢、急尖長苞冷杉+苔蘚群叢。

This article selected the natural forest of Abies georgei var.smithii at MountSejila as research object .The Analytic Hierar-chy Process (AHP method) extracted the most important assessment indexes in many factors ,which belonged to biological diversity and characteristics of the community,used principal component analysis and Analytic Hierarchy Process (AHP method) to arrange healthy indexes.The results show that the greatest impact on the health of the community structure to forest of Fir community followed age structure,shrub coverage,tree quantity,regeneration quantity,herb species,canopy density,herb coverage,shrub species,tree species,and sub-layer.The health sortings were Ass .Abies georgei var.smithii-Picea likiangensis var.linzhiensis,Ass.Abies georgei var.smithii+Lonicera spp.,Ass.Abies georgei var.smithii+Rhododendron spp.and Abies georgei var.smithii+Bryophyta spp.Ass.
