侵蚀性降雨对黑土坡耕地土壤侵蚀特征的影响

open access: yesShuitu Baochi Xuebao
[目的] 降雨是黑土坡耕地水力侵蚀的动力来源,研究天然降雨条件下坡耕地土壤侵蚀特征对水土流失防治具有重要意义。[方法] 基于黑龙江省海伦市光荣小流域2021—2022年不同坡度(3°,5°和7°)顺坡垄作径流小区观测的43场次侵蚀性降雨事件,采用K-Mean聚类法对比分析不同雨型和坡度下径流与输沙特征,并探讨影响坡耕地径流与输沙的影响因素。[结果] 研究区以短历时、大雨强、小雨量的降雨(雨型3)为主,其次是中等历时、中等雨强、中等雨量的降雨(雨型2),长历时、小雨强、大雨量的降雨(雨型1)极少发生 ...
