摘要:
长江上游区域水土流失现象已引起广泛关注,通过土壤侵蚀的间接指标计算,表明长江上游亚高山天然林区表层土壤侵蚀率较小,丘陵区人工林区表层土壤侵蚀率较大.定量分析表明,土壤有机质含量、土壤团聚体稳定性、土壤渗透性能等因素对土壤侵蚀率影响较大,相关系数和回归分析均达到了0.01极显著性水平.其他因素如林地凋落物和地面植被也对土壤侵蚀产生明显影响.
Abstract:
The soil and water loss in upper reaches of the Yangtze River has arisen broad attention.The authors calculated the indirect indexes of soil erosion,which showed that low soil erosion ratio under sub-alpine forests and higher erosion ratio under hilly artificial forests.The quantitative analysis showed that soil organic matter content,stability of soil aggregates,and saturated soil infiltration are main factors influencing soil erosion ratio with both correlate coefficients and regression analysis through the most significant test at level 0.01.Other factors such as wither and ground vegetation are also influential factors.
