| Abstract: | It is very important of well-formed soil structure to forest hydro-ecological function. Soil samples are taken from subalpine natural forest and hilly area artificial forest of upper reaches of the Yangtze River,and quantitative component of aggragates and the physical and chemical properties are also analyzed. The main factors of soil aggragates formation and stability were maken certain using correlation analysis,and the aggragate formation and stable model of temporary aggragate,sub-stable aggragate,and stable aggragate is put forward. |
