中文摘要	研究塔里木河中下游湿地及其周边土壤理化性状,包括土壤粒度组成、土壤水分、盐分、pH和养分的空间异质性结果表明:大范围分布的土壤质地以沙质或粉沙质壤土为主,少数属壤质沙土或粉沙土,不同类型土地或植被条件下土壤粒度组成存在差异;土壤水分的空间分布特征反映了塔里木河中下游湿地的旱化现象;广泛分布的盐土、盐渍化土和碱化土表现出对植物生长发育的明显胁迫作用;土壤有机质、全N和全P 总体贫乏,全K含量较高,反映了干旱区湿地土壤的特点.
英文摘要	By analyzing the spatial heterogeneity of soil physical-chemical properties, including soil particle sizes, soil moistures, soil salt-contents, pH and soil nutrients for 70 samples from 16 quadrants of the wetlands and surrounding lands in the middle and lower reaches of Tarim River, this paper shows that the soil textures of most samples are the sandy loams or silty loams and few samples are loamy sand soils or loamy silt soils. The compositions of the soil particle sizes for different land-uses and vegetations have some differences. The special distributions of the soil moistures present the aridization of the wetlands in the middle and lower reaches of Tarim River. The solonchak, salinized and alkalized soils with an extensive area represent a significant stress to the plant growth and development. That the levels of the organic matter, total N and P are generally poor indicate the characteristics of the wetlands in the arid area.
