Abstract: In this paper, the nutrient characteristics of five kinds of aeolian sandy soils sampled from Yulin municipality of northern Shaanxi Province were studied Among these soils, moving, semifixed, and fixed aeolian sandy soils are formed under natural conditions, and cultivatedfixed, irrigatedfixed aeolian sandy soils are formed through artificial cultivation activities The results showed that with the increase of vegetation, moving dunes were gradually fixed, the nutrient content of surface soil gradually increased from moving aeolian sandy soil to semifixed and fixed aeolian sandy soil because the fine grains, which contain more nutrients, were not blown away at a large degree and the content of fine grains in soils gradually increased after vegetation cover improved The contents of soil organic matter and nitrogen decreased because of the accelerated mineralization of organic matter by human activities Meanwhile, application of phosphorus fertilizer made the available phosphorus enhance The irrigatedfixed aeolian sandy soil, the principal farmland in Yulin municipality, was intensively affected by artificial production activities The fertility of irrigatedfixed aeolian sandy greatly improved by irrigation and fertilization, so the soil nutrient content was higher than that of other soils
