| 摘 要： | 炼山后板栗林地土壤孔隙度大大增加 ,其增加程度取决于非毛管孔隙度的增加 ;土壤中大于 0 .2 5 mm的水稳性团聚体含量降低 ,虽改善了土壤的通透性和肥力 ,但遇强降雨时 ,坡度较大的林地易引发水土流失

| Abstract: | The soil porosity increase greatly after mountain smelting and the increase degree depend on the increase of uncapillary porosity. Despite the decrease of water steady granule quantity bigger than 0.25 mm in the soil improving the aerate and fertility of soil,stands on steeper slope take place soil erosion easily when it meet strong rainfall. |
