| 摘 要： | 本文利用人工降雨试验和野外调查资料分析研究了黄土高原坡耕地细沟侵蚀发生发展的影响因素.其结果表明:降雨径流能量(尤其是径流能量)、土壤抗侵蚀性能、坡度、坡长、坡形、土地管理是影响细沟侵蚀的主要因素.作者认为防治坡耕地土壤侵蚀的关键是削弱降雨能量和提高土壤的抗侵蚀性能.

| Abstract: | Study on affecting factors of rill formation and development was conducted by using simulated rainfall and field investigation. The results have been shown that rainfall and runoff energy (especially runoff energy), soil erosion durability, slope degrees length, shape and land management are principal factors affecting rill erosion. For this reason, the authors consider that the key measues to control rill erosion is to reduce rainfall and runoff energy and to improve soil erosion durability. |
