尼勒克县不同类型城市绿地物种组成与群落结构分析

Analysis on Species Composition and Community Structure of Different Types of Urban Green Space in Nilka County

对尼勒克县4种典型的城市绿地,在采用典型样地调查和数据收集的基础上,分析不同绿地的物种组成和群落结构多样性,结果表明:城市绿地中公园绿地植物种类有17科、26属、33种,优势物种少,乔灌草配置比例不合理,树木多以单种成片的形式出现;附属绿地绿化植物种类有30科、54属、67种,树种虽然较多,但缺乏运用多种植物来造景和对阳台、屋顶、院墙、围栏等的垂直绿化,现有的垂直绿化物种少;防护绿地植物种类有5科、5属、10种,生产绿地植物种类共计9科、12属、14种,这两种绿地存在树种单一,结构简单,稳定性差。

Based on the collected data, the species composition and community structure of four typical urban green spaces were analyzed by using typical sampling investigation. The results show that the plants in park green space mainly belong to 17 families, 26 genera and 33 species with few dominant species, the allocation proportion of arbor - shrub - herb is unreasonable, and most of community is formed by single tree. In attached green space, the plants belong to 30 families,54 genera and 67 species, and the plant species is richer than that in the park green space, but due to a lack of a variety of plants to use for landscaping and the vertical greening on the balcony, roof, walls and fences, the existing vertical greening species is less. There are 5 families, 5 genera and 10 species in protection green space, 9 families, 12 genera and 14 species in green land for production. And both the two kinds of green space have a single species, simple community structure, and poor stability.
