- W2369251036 abstract "The soil properties under natural Sabina vulgaris shrub in Mu-us sandy land were reserched with plot investigation. The result showed that distribution patterns of soil moisture, organic matter, total N, available K and hydrolytic N presented spatial heterogeneity. The average content of middle and fine soil particles(0.25～0.02mm) in layer of 0～5cm under Sabina vulgaris shrub(70%～85% cover)which was 9% higher than that under Artemisia ordosica shrub(40%～55% cover) ,was 68.9%, and it dropped down with increasing deep. The soil nutrients, such as organic matter, total N, available K and hydrolytic N, and the soil moisture showed an evident phenomenon of “island of fertility” under Sabina vulgaris shrub. The soil samples with 1%～2% of moisture was over 60%, and variation coefficient of soil moisture was 113% in layer of 0～100cm. The soil moisture decreased gradually from the center of shrubs to its edge in layer of 0～20cm but it showed opposite trend under layer of 20cm. The content of available P was less than 2mg/kg. The organic matter, total N, available K and hydrolytic N of soil massed over layer of 20cm. The variation coefficient of organic matter was 96.3%, of total N was 101.4%, of hydrolytic N was 80.6% ,and of available K was 88.4% in layer of 0～100cm. The spatial heterogeneity of soil resources resulted from the process of the biology and the physics." @default.
