| Abstract: |
| By analyzing the mechanical composition of soil particles in different profile depth of 29 farmlands in Zhangwu County,the desertification degree(DD) of farmland soil was quantificationally classified,based on the rate of large particle(>0.1mm) content to small particle(≤0.1mm) content.The hierarchies were as follows: Ⅰ(DD>5),very severe;Ⅱ(2 |
