| Abstract: | The research results showed that in the desertification process of the soils,silt content,organic matter,available nutrients and water-holding capacity were gradually reduced but soil temperature ane pH rose;Worsening of the soil properties resulted from decreasing of silt and clay particles and organic matter caused the coarsing of soil particles,the lowering of water-holding capacity and the loss of nutrients in the process,the danger by wind erosion of soil was more serious than that by wind deposition;and in the desertification process of farmland soils,worsening of soil physical and chemical properties had both continuity and discontinuity. |
