中文摘要	以额济纳荒漠典型红砂(Reaumuria soongorica)群落为样本,通过测定土壤的理化性质、水势以及红砂根系分布,研究红砂根系分布与土壤环境的关系。结果表明:红砂主要分布在灰棕漠-灰漠土地带,而其根系主要集中在pH8.0-8.97之间、电导率高达1.19-1.78ms /cm的地下30-70cm层,该层不但含盐量很高,含水率也较高;可以认为,土壤水分、盐分是影响红砂根系分布的主要因素,而红砂根系集中分布在盐化层和高含水层则是长期适应土壤环境的结果。
英文摘要	In this study,three typical Reaumuria soongorica communities in Ejina Desert were selected as sampling sites. Physiological and chemical properties of soil,water potential,and root distribution of R. soongorica were surveyed and measured. The relationship between the root distribution of R. soongorica and soil properties were analyzed. The results showed that R. soongorica was mainly distributed in the zone of gray brown desert soil-gray desert soil. It’s roots were distributed in the soil between 30-70cm,within soil pH level of 8.02 ~ 8.97, and soil electric conductivity was of 1.19 ~ 1.78ms /cm. Thus,it suggests that soil salinity and soil moisture content were principal factor that influences the roots distribution of R. soongorica within the salinzed layer of soil.
