冲沟是多种外力作用的结果,展示为多种地貌现象。选择胶东半岛北岩子口小流域作为研究对象,以正射影像（DOM）和数字高程模型（DEM）为数据源,选择土地利用、地形湿度指数、坡度坡长因子、水流动力指数、坡向、平面曲率和地表粗糙度等7个地貌因子,计算小流域土壤侵蚀敏感性,研究侵蚀冲沟与地貌因子的关系。结果表明:冲沟多发生在坡度坡长较大、水流动力强、地表湿度较低的林草地区域,多分布在阳坡的凹面;冲沟大多分布...
参数λ是SCS产流模型的一个重要参数,模型研究者将标准值λ=0.2作为模型的参数值。但模型参数没有考虑地貌类型对产流的影响,喀斯特地区不同地貌类型下地表坡度、土层厚度、地层岩性、基岩裂隙的发育程度等方面均存在很大差别,而这些因素都直接影响着流域的产流机制。在考虑地貌类型对喀斯特流域产流影响的基础上,通过率定不同地貌类型下的λ值对SCS模型进行改进。以GIS和RS技术作为获取流域地貌类型、土壤类型和...
