大通县东峡林区青海云杉林物种组成及结构特征研究

Research on Species Composition and Structure Characteristics of Picea crassifolia Forest Dongxia Forest Area Datong County

本文对东峡林区青海云杉林的物种组成及其结构特征进行了研究,结果表明,青海云杉林的物种组成及结构特征受其物种分布水平地带性和垂直地带性的影响,青海云杉林有着迥然不同的结构组成,在垂直结构上可以分为:乔木层,灌木层和草本层,青海云杉林种群呈聚集分布,具有较强的独立性,组成的群落也能够容纳较多的物种,并使群落保持稳定。

In this paper, the species composition and structural characteristics of Picea crassifolia Forest Dongxia forest were studied, the results show that the species composition and structural characteristics effected by horizontal zonality and the vertical zonality species distribution, Picea crassifolia forest has a very different structure, vertical structure can be divided into： tree layer, shrub and herbaceous layers, which showed aggre- gated distribution, with strong independence, consisting of community also be able to accommodate more spe- cies makes communities stable.
