摘要
调查的5个林业局内天然阔叶混交林各林层的树种多样性指数和丰富度指数呈现相同的变化规律,演替层树种多样性指数和丰富度指数最高,主林层树种均匀度指数最高;更新层树种多样性指数、丰富度指数和均匀度指数最低。五营林业局试验区林分群落多样性指数和均匀度指数最高,而新青林业局试验区林分群落丰富度指数最高。小兴安岭林区天然阔叶混交林整体上树种组成比较复杂,树种多样,属典型杂木林结构。
Diversity indexs and richness indexs of natural broad-leaved mixed forest in the test areas regeneration layer are the lowest. Diversity indexs and evenness index of trees in Wuying are the highest, but richness indexs of trees in Xinqing forestry bureau is the highest forestry bureau , Tree species composition is relatively complex. Natural broad-leaved mixed forest in the Xiaoxing＇anling mountains is a typical complex forest structure.
