| 中文摘要: |
| 通过对采自彰武地区29个农田土壤剖面不同深度土壤颗粒的机械组成分析,根据粒径>0.1 mm与≤0.1 mm颗粒含量的比值DD(desertification degree)的大小,定量地划分农田土壤沙化程度等级,各等级为:Ⅰ(DD>5),极严重沙化;Ⅱ(2 |
| 英文摘要: |
| 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 |
