摘要
以黄土区(淳化径流小区)为研究对象,通过人为管理措施界定不同的地表糙度,选定地表糙度测定方法及求算指标,分析管理措施对糙度的影响,并提出了黄土区坡耕地地表糙度的定义,结合黄土区地表起伏的数量特征,得出了该区坡耕地地表糙度的界限,为土壤侵蚀预报的建立提供了基础材料。
Taking the runoff area of Chunhua County in Loess Plateau as research object, determination and calculation about surface roughness were selected and the effects of cultivation management on roughness were analysed, and the definition of surface roughness on slope farmland in Loess areas was put forward. The ranges to surface roughness were obtained in theory by combating with the quantitative features of surface rising and falling in Loess areas. It would provide basic data for soil erosion prediction.
