黑土区坡耕地侵蚀沟发育机理
Mechanism of Gully Develop on Slope Farmland in Black Soil Area, China
摘要
Abstract
Gully erosion of live watershed in black soil area was investigated.Distribution and configuration of gully were analyzed.And it was found that gully erosion mainly happened on slop farmland.After calculating the amount of confluent of run carrying by contour ridge and ditch,it was found that one of the important of gully developing fast was caused by the change of the slope ridge and ditch into contours.Therefore,multi-measure integrated into system should be the eolution to the problem of gully erosion in the Northeast Black soil area of China.关键词
