中文摘要	对盐池县潜在沙漠化草地、轻度沙漠化草地、中度沙漠化草地、重度沙漠化草地和极度沙漠化草地5种不同沙化类型草地土壤理化特性进行研究,以探讨沙漠化对土壤环境的影响.结果表明:土壤含水量为潜在沙漠化草地>轻度沙漠化草地>中度沙漠化草地>重度沙漠化草地>极度沙漠化草地;土壤黏、粉粒及有机质、全氮等养分含量总体为由潜在沙漠化草地到极度沙漠化草地逐渐降低,砂粒含量逐渐增加,pH和可溶性盐含量无明显变化规律.该地区土壤组成主要以砂粒为主,土壤含水量低,养分贫瘠,环境脆弱,易产生风蚀、沙化.
英文摘要	The soil physical and chemical properties in potential desertification grassland, light desertification grassland, medium desertification grassland, severe desertification grassland and extreme desertification grassland in Yanchi were studied to explore the impact of desertification on soil environment. The results showed that: the soil water contents were in the descendant order of potential desertification grassland, light desertification grassland, medium desertification grassland, severe desertification grassland, and extreme desertification grassland. Soil clay, silt, organic matter, total nitrogen content decreased, while sand content increased from the potential desertification grassland to the extreme desertification grassland. Changes of Ph and soluble salinity content had no obvious trends. Overall, the main soil particle size is sand, the soil moisture and nutrient contents are very low. The soil environment was fragile and erodible.
