黄河河龙区间河流泥沙对相关重大事件与政策的响应

, 2009
利用径流- 输沙量双累积曲线与单位降雨侵蚀力输沙量(输沙量负荷)的分析表明,河龙区间泥沙变化与相关重大事件与政策密切相关。“大开荒”时期输沙量负荷平均值最大,是输沙量负荷多年平均值的1. 8倍; “大跃进”、“农业学大寨”和“文革”时期的输沙量负荷均值也较大,为输沙量负荷多年平均值的1. 4～1. 5倍。改革开放后,输沙量负荷下降明显,输沙量负荷平均值较改革开放前减少了55.

Response characteristics of sediment to human activities in the Songhua River basin

对松花江流域主要水文站输沙量变化的分析表明:51年来,嫩江除1998年发生洪水外其余年份输沙量变化不大,第二松花江输沙量表现为明显的下降趋势,松花江干流输沙量也表现为下降趋势,而松花江整个流域在1979年之前为下降趋势,1979年之后为上升趋势。松花江干流区域和第二松花江为主要的泥沙来源区,分别占整个松花江流域输沙量的72.1%和16.2%。通过对单位降雨侵蚀力输沙量的分析,松花江流域输沙量负荷的变化与流域内重大历史事件、国家政策等人为活动的变化密切相关。"大跃进" ...

嘉陵江流域水土流失严重,是长江流域重点产沙区之一,研究流域输沙量演变规律及其影响因素,对揭示其水土流失规律及人类活动水文效应具有重要意义。基于嘉陵江北碚站月及年输沙量,分析了流域输沙量演变规律及流域内人类活动对输沙量的影响。结果表明:年输沙量总体呈降低趋势,1980s—1990s年输沙量波动程度相对较大;流域年输沙量在1992年发生突变,突变年份后年径流量有所增加,年输沙量明显减少,突变年份后年输沙量波动程度加剧;年内输沙量主要集中在汛期(7—9月),占全年72%以上 ...

侵蚀性降雨对黑土坡耕地土壤侵蚀特征的影响

Shuitu 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 ...
