Shuitu Baochi Xuebao, 2016 以长江中上游典型侵蚀性土壤紫色土为研究对象，采用变坡限定性细沟土槽，研究不同流量、坡度和沟长情况下，紫色土细沟侵蚀特征，并量化了细沟侵蚀参数。结果表明：细沟侵蚀受水流水力特征、土壤性质和坡面影响，随着水流含沙量的增大，细沟侵蚀速率呈现减小趋势；流量越大，坡度越陡，细沟水流的剥蚀率越大，造成细沟侵蚀速率也越大。在5 L/min的小流量下，细沟侵蚀速率受剥蚀率限制与含沙量没有出现线性关系，15，25 L/min流量下，细沟侵蚀速率与含沙量呈线性相关。侵蚀速率在细沟开始处最大，随沟长的增大 ...

Shuitu Baochi Xuebao, 2002 通过对砒砂岩区西召沟小流域冻融风化侵蚀实测资料的分析,认为砒砂岩区冻融风化侵蚀主要发生在裸露沟谷坡面,其冻融风化侵蚀与砒砂岩的种类有关。与同种砒砂岩相比,种植沙棘7年后,支沟上、中、下游的坡面冻融风化侵蚀模数平均从11748t/km2降为3535t/km2,降低69.9%。单位长度沟沿线与沟角线和的冻融风化侵蚀量平均从0.0974m3/m降为0.004m3/m,降低95.9%。冻融风化侵蚀量占整个沟道总产沙量的百分比上游从76.1%降到52.6%,下游从6.4%升到13.2 ...

Shuitu Baochi Xuebao, 2022 作为黄河流域典型生态脆弱区之一的砒砂岩区,水土流失治理难度大,区域地形、侵蚀在坡沟系统的分布迥异。区域土壤侵蚀研究多集中于刻画侵蚀空间分布及不同地类差异性研究,从坡沟系统细化开展研究工作较少,不能较好地为后续精细化治理提供支撑。因此,选取位于准格尔旗的3个典型砒砂岩区小流域,结合目视解译的流域沟沿线,开展了流域地形、水力侵蚀分布规律及其关联性研究。结果表明:流域地形因子分布特征与地貌特征分布一致,高值集中分布在沟道,低值则集中在坡面,且特拉沟小流域(覆沙)沟道处的地形因子统计值最大 ...
