【摘要】 对乌拉特灌木优势种进行了统计分析,以为该地区的生态保护后期工作提供数据支持。通过样方调查法对该地区种优势灌木进行了研究,结果表明:乌拉特地区共有野生灌木植物群落50种,隶属于11科,29属;其中优势灌木为20种,对20种优势灌木群落的盖度、高度、数量生物量、干鲜比进行了统计分析,从中选取6种典型灌木,得出了灌木地上生物量与土壤含水量、孔隙度有显著性的关系,而与土壤容重之间没有显著性关系。更多还原

【Abstract】 Ulat is an important part of the barrier in northern China, and shrubs are an important part of plant composition. Statistical analysis on the dominant species of Urad shrubs are carried out, which provides data support for the later work of ecological protection in this area. The dominant shrubs in this area is studied by quadrat investigation, and the following conclusions are reached:(1) there are 50 wild shrub communities in Urad area, belonging to 11 families and 29 genera; Among them, there are 20 dominant shrubs. The coverage, height, quantitative biomass and dry-fresh ratio of the 20 dominant shrub communities were statistically analyzed. Six typical shrubs were selected, and it was found that the aboveground biomass of shrubs had a significant relationship with soil water content and porosity, but had no significant relationship with soil bulk density.更多还原
