【摘要】 本文提出用侵蚀率(单位径流深度所产生的侵蚀深度)来描述土壤的抗蚀能力,并用侵蚀率比较同一地区不同时段或同一时段不同地区土壤抗蚀能力的变化,以监测人为活动,包括植树造林等水土保持措施,以及人为不合理的社会经济活动,对水土流失的影响。据笔者对浑泥港流域水土流失趋势的分析结果,用侵蚀率描述水土流失有明显的优越性。更多还原

【Abstract】 This paper proposed that the anti-erodibility of soil could be described by erosion ratio (erosion depth per unit runoff depth), and could also be used to compare the different anti-erodibility of soil in different areas in a same period, or in the same area in different period, in order to monitor the influence of human’s effection on soil erosion, for example, arbitrarily felling of trees, afforestation and soil and water conservation. By analyzing the tendency of soil erosion in the Hunnigang watershed we found that to describe soil erosion with erosion ratio has many advantages.更多还原
