线叶忍冬群落区系和组分研究

Study on the Floristic Genera and Texture of the Community of Lonicera alberti

在昭苏县线叶忍冬分布区内设置典型样地,对典型杨地内的植物种类、高度、株(丛)数、盖度等特征进行调查统计。结果表明:线叶忍冬群落物种丰富度较高,由39种植物组成,隶属于23科34属,其中蔷薇科、豆科、菊科、龙胆科为主要组成科,委陵菜属、獐牙菜属、忍冬属为主要组成属,科、属的分布型以温带成分占优势,属于温暖气候带的植被成分;地面芽植物比例较高;主要层植物灌木叶片以微型叶、单叶、草质、全缘叶为主,叶片特点体现其属于山地河谷落叶阔叶灌丛。

Sample plots were established in the distribution area of Lonicera alberti in Zhaosu county.Its plant species and community were investigated,and characteristics such as plant species,floristic element,texture in standard were analyzed.The results showed that the species richness in the community of Lonicera alberti was higher.This community was composed of 39 species in 34 generas and 23 families.The main families including Rosaceae,Leguminosae,Compositae,Gentianaceae,and the main genera including Potentilla,Swertia,Lonicera.The temperate had absolute dominance on the distribution types of families and genera,reflecting its belong to canopy elements of the warm temperate zone.Hemicryptophyte occupied the highest ratio.Nanophyll,sigle leaf,orthophyll,entire margin leaf were dominant of leaf characteristics in the main synusia of community.Entire leaf mainly,foliar characteristics reflected which belong to the mountain valley deciduous shrub.
