【摘要】 通过对阿伦河流域水土保持林内土壤抗蚀性能的试验 ,提出了阿伦河流域水土保持林不同林种、不同树种对土壤的物理性质、结构、有机质及抗蚀性都有不同程度的提高或增强 ,并总结出在阿伦河流域以落叶松、小黑杨、柳树为主体的水土保持林 ,对土壤抗蚀性能提高最大 ,为阿伦河流域水土保持林树种选择提供理论依据。更多还原

【Abstract】 Experiments of erosion resistance of soil in soil and water conservation forests in Alunhe river basin Showed, that soil and water conservation forests of different tree species all raised soil physical property, Structure, content of organic matter as well as erosion resistance. Especially, erosion resistances of the forests that compose of larch, willow were highest. The research provided theoretic basis for tree species selection of soil and water conservation forests in the Alunhe river basin.更多还原
