中文摘要	该文以半干旱荒漠区典型湖泊红碱淖为例,分析水分减少引起流域土地利用/覆盖类型发生变化进而对土壤理化性质特征产生的影响。结果表明,红碱淖湿地流域土地利用类型呈现以湖泊为中心由盐碱沼泽向沼泽化草甸、草地、草原化沙地、沙地变化,土壤粉粒和黏粒含量减少,砂粒增加,土壤含水量降幅19.17%~82.20%。与盐碱沼泽相比,沼泽化草甸、草地、草原化沙地、沙地土壤有机质含量分别下降了7.73%、32.01%、52.32%、53.42%;全氮含量分别下降了2.05%、4.46%、31.56%、34.15%;全磷含量分别下降了34.82%、36.80%、31.40%、47.25%。深层土壤有机质、全氮、全磷含量在不同土地覆盖类型中差异更明显。土壤有机质、全氮和土壤全磷含量与土壤粒度存在显著相关关系。
英文摘要	Effects of land use/cover change on soil properties caused by water change were studied in Hongjiannao watershed in the sub-arid desert area. The results showed that land use/cover types in the watershed changed along with the water level,which were salt swamp,swampy meadow,grassland,sand grassland and sand. According to this trend,sand grains content in soil increased while clay and silt grains decreased,and soil moisture content reduced by 19.17%~82.20%. Compared with salt swamp,soil organic matter in other land use types reduced by 7.73%, 32.01%, 52.32%, 53.42% respectively,total N reduced by 2.05%,4.46%,31.56%,34.15% respectively,and total P reduced by 34.82%,36.80%,31.40%,47.25% respectively. Meanwhile,soil organic matter,total N and total P in underlying soil (30~50 cm)were more different than that in surface soils of various land cover types. Soil organic matter,total N and total P were significantly correlated with soil particle composition.
