摘　　要：本实验主要选取鄂尔多斯遗鸥湿地保护区周边的不同植被覆盖下的土壤为研究对象,并布设一条长500 m宽50 m的样带确定研究植被的类型,采用主成分分析和土壤质量指数相结合的方法进行土壤质量综合评价。得出以下结论:(1)盐爪爪样地和苦豆子样地的土壤容重和含水率较高,为1.9 g/cm^(3)和1.96 g/cm^(3);柽柳的孔隙度最大,为44%;芨芨草样地和盐爪爪样地电导率最高。(2)本次实验样地土壤为碱性,pH值均在8以上;莳萝蒿样地的有机质含量最高,为8.22 g/kg。(3)各种植被类型土壤质量评估排序为,莳萝蒿样地>油蒿样地>盐爪爪样地>芨芨草样地>苦豆子样地>柽柳样地。The soil under different vegetation covers around the Ordos Relict Gull Wetland Reserve was selected as the research object,and a transect with a length of 500 m and a width of 50 m was laid to determine the type of vegetation for study,and the soil quality was comprehensively evaluated by a combination of principal component analysis and soil quality index.The following conclusions were drawn:(1)The soil bulk density and moisture content of the Kalidium foliatum and Sophora alpecuroides plots were higher(1.9 g/cm^(3) and 1.96 g/cm^(3)),the porosity of Tamarix chinensis was the largest,which was 44%,and the conductivity of the Nevtrinia splendens and Kalidium foliatum was the highest.(2)The soil in the experimental plot was alkaline,and the pH value was above 8,and the organic matter content of the Artemisia anethoides sample plot was the highest,which was 8.22 g/kg.(3)The soil quality of various vegetation types was evaluated in the order of Artemisia anethoides samples>Artemisia ordosica krasch plots>Kalidium foliatum plots>Nevtrinia splendens plots>Sophora alopecuroides plots>Tamarix chinensis plots.
