| 摘 要： | 对干热河谷地区4种典型土地利用类型坡地的土壤物理性质对土壤侵蚀的影响进行研究.利用环刀法分别采样,分析表明:土壤物理性质是影响土壤侵蚀和土壤抗蚀性能的内在因素,干热河谷地区土壤贫瘠化特征明显,不同土地利用方式下,林地和草地比耕地和荒地的土壤物理性状好,因此能有效缓解土壤侵蚀的发生发展,发挥保持水土的作用;4种土地利用类型的土壤抗蚀能力大小依次为林地＞草地＞耕地＞荒地.

| Abstract: | Effect of soil physical properties on soil erosion under four different land uses was conducted in the dry and hot valley region.Soil samples were collected by the cutting ring method.The results indicated: Soil physical properties were the internal factors which had an significant effect on soil erosion and soil anti-erodibility.The soils in the dry and hot valley region are distinctly characterized by soil impoverishment.In addition,under various land uses,soil physical properties of forestland and grassl... |
