中文摘要	天然植被是抑制荒漠化过程及保护生物多样性的重要因素。为探讨荒漠化地区的土壤理化性质及其与胡杨林生长间的关系,以塔里木胡杨国家级自然保护区为研究区,采用样地调查、取样试验与分析相结合的方法,比较了区内不同样地的土壤理化性质与胡杨长势。结果表明:研究区内土壤机械组成在塔河南岸以粉粒为主,北岸以细砂粒占优势,胡杨林在粉质、砂质壤土上长势良好;胡杨生长良好地区土壤pH值在7.83~8.00;0-20 cm土层有机质在0.33%~0.80%,含盐量在0.42%~6.28%,盐分以水溶性硫酸盐与氯化物为主,不同样地土壤理化指标差异显著。在塔河中游荒漠绿洲地带,土壤盐碱化是影响胡杨林繁衍发育的主要因素,排盐在促进胡杨更新复壮过程中至关重要。
英文摘要	Natural vegetation is one of the key factors in the conservation of biological diversity and desertification control. In order to study the physical and chemical properties of soil and their effects on the growth of Populus euphratica in desertification-prone areas,we took Tarim National Nature Reserve as the research area. Through the field investigation and sample collection and analysis,the results were obtained as follows. Soil particle in the south bank of middle reach of Tarim River mainly composed of silt,however, fine sand preponderated in the north bank. Populus euphratica grew well in the silty loam and sandy loam; the soil pH value between 7.83 and 8.00 was suitable for the growth of Populus euphratica; the soil salinity totality in 020 cm depth was greater than 0.4%,and the content of soil organic matters was 0.33% ~ 0.80%,the salt content was 0.42% ~6.28% in the studied area. The salt took hydrosoluble sulfate and chloride as the principal substance; they were statistically different in the soil physical and chemical properties of different regions. In the middle reaches of Tarim River,soil salinization and alkalization were the dominant factors inhibiting the growth of Populus euphratica forest. Reducing the salt amount in soil was a preferential measure for ecological recovery.
