不同生境下柠条根际环境植物多样性研究

Study on Plant Diversity in Rhizosphere Environment of Caragana in Different Habitats

为研究不同生态环境下柠条根际环境与植物多样性的关系,对内蒙古生态环境不同的4个地区中柠条根际环境的植物种类进行统计分析。结果表明,柠条根际环境有利于增加植物多样性;不同地区不同的生态环境影响柠条根际环境的植物多样性,年均气温、年均降水量均对植物多样性具有显著影响;4个地区柠条根际环境的优势种多为菊科植物,而对照区的优势种则多为禾本科植物。

In order to study the relationship between Caragana rhizosphere environment and plant diversity in different ecological environments,this study conducted a statistical analysis on the plant species of Caragana rhizosphere environments in four regions with different ecological environments in Inner Mongolia.The results showed that Caragana rhizosphere environment was conducive to the increase of plant diversity.Different ecological environments affected the plant diversity in Caragana rhizosphere,and the average annual temperature and precipitation had significant influence on the plant diversity.The dominant species were mainly Compositae in Caragana rhizosphere in the four areas,while the dominant species were mostly Gramineae in the control areas.
