Wang, Y.; Zhang, L., and Haimiti, Y., 2015. Study on spatial variability of soil nutrients in Ebinur lake wetlands in China.

Three typical regions were selected in Ebinur Lake wetlands of Xinjiang in China, and the nutrient content of their soil was determined with analytical chemistry approaches. Based on the chemical information, the Geostatistics method was employed to analyze the space variability of the soil nutrients for each region. The results were that the comprehensive nutrients level of Region C (Aqikesu River) was higher than those of Region B (Jinghe and Bortala River) and Region A (Alashankou). There is a strong spatial autocorrelation for the soil nutrients studied. Soil organic matter, nitrogen, available phosphorus in every region showed moderate variability, and the variability of potassium depended on the region. The spatial variability of soil nutrients is assumedly caused by climate, topography, soil type, etc. The study is of great significance in understanding the forming process of soil, as well as in providing scientific reference for restoring of soil degradation and dust resistance of the regions studied.
