【摘要】 受西北地区环境条件的影响,东部地区生长良好的植物在此受到限制。文章以适应西北干旱盐碱瘠薄生境条件的自然群落为研究对象,分析5组自然花境植物群落的空间结构。研究结果表明:(1)5个样地的群落共有物种15科29种,以豆科、禾本科、菊科的物种居多。(2)5个样地的优势种主要是花木蓝、柽柳、沙冬青、披碱草、野古草、蒙古蒿、车前、黄耆。(3)对5个样地的群落结构进行分析,结合群落的生态功能和适应性,筛选出以花木蓝+披碱草为优势种的花境群落,最终设计出适应西北地区城市绿地的自然花境植物配置模式。更多还原

【Abstract】 Due to the environmental conditions in the Northwest China,the plants that grow well in the East China are restricted here. Taking the natural communities adapted to arid saline-alkali barren habitat conditions in Northwest China as the research object,this paper analyzed the spatial structure of five groups of natural flower plant communities. The results show that:(1) There are 15 families and 29 species in the communities of the 5 plots, most of which are Legumes, Gramineae and Compositae.(2) The dominant species in the 5 sample plots are Indigofera kirilowii,Tamarix Hohenackeri,Ammopiptanthus Mongolicus,Elymus Dahuricus, Arundinella Anomala,Artemisia Mongolica,Astragalus Propinquu.(3) By analyzing the community structure of the five sample plots and combining the ecological functions and adaptability of the communities, the flower-boundary communities with the dominant species of Indigofera kirilowii +Elymus Dahuricus are screened out,and the natural flower-boundary plant configuration pattern suitable for urban green space in Northwest China is designed finally.更多还原
