| Abstract: | The southeast Qinghaicozang (Tibetan) Plateau is a physcal mpon ofvery complicated eco-envirorunent with optimum hydrothermal conditions. Thisregon conains not ouly vast expanse of alpine soils but also abounds in mosttypes of Chinese forest soils. The distributon and tallization of soils presents avery evident horizontal-vertical zonality. At present, panial soil resources arebeing damaged and the mountain ecology also tends to be instable. So rationalcuttin and forest conservation, barren mountain afferestation, retuming thecultivated land on stop slopes to forest, controlled graking, and soil ameliorationconstitute importan means for rational use of soil resources and improvement andstabilization of mountain ecology in tyis region |
