Comprehensive evaluation of soil quality under different vegetation types in Ordos Relict Gull Reserve
The soil under different vegetation covers around the Ordos Relict Gull Wetland Reserve was se-lected 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/cm3 and 1.96 g/cm3),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 alopecu-roides plots>Tamarix chinensis plots.
