【摘要】 塔里木盆地胡杨群落植物种类少,植被结构简单,构成了典型的荒漠河岸林景观。群落的生活型以高位芽植物为主,地面芽植物次之,该群落叶的性质以小型叶、单叶、革质、非全缘为主,群落垂直结构单一,地上成层明显,可分为乔木层、灌木层和草本层,乔木层→灌木层→草本层物种多样性依次递增,优势种胡杨种群的年龄结构属稳定型。更多还原

【Abstract】 There are few plants in the community of populus euphratica and the vegetation structure is simple,forming the desert galleria landscape.In terms of genus geographical elements,many of them are distributed in cosmopolitan.According to Raunkiaer’s statistics of life-form,the number of phaenerophyte life-form of this community is of dominant type,followed by the hemicryptophyte.The characteristics of the community leaf is mainly microphyll,simple,leathery and unentire.The vertical structure of community is relatively simple which can be divided into tree layers,shrub layer and herb layer as well as a definite number of interstratum plants.The species diversity increases progressively from tree,shrub to herb layer.The age structure of populus euphratica is stable.更多还原
