| Abstract: | The paper, taking the soil and water conservation forest as a object of study, analy-ses the soil-fixing effect and sets up the grey models for soil-fixation amount and soil-fixation effi-ciency of soil and water conservation forest in the area.The result of examination and test for soilsample from the forest land shows that the soil nature of forest land has been greatly improved. |
