| 摘 要： | 对黑土区5个小流域开展侵蚀沟调查,分析了侵蚀沟的分布和形态特性,发现侵蚀沟主要发生在坡耕地上。通过对垄作的汇流进行计算,发现造成沟蚀快速发展的原因之一是坡耕地实行单一的横坡垄作。因此,在东北黑土区采取水土保持综合措施可防止坡耕地水土流失。

| Abstract: | Gully erosion of five 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 off carrying by contour ridge and ditch,it was found that one of the important reasons 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 solution to the problem of gully erosion in the Northeast Black soil area of China. |
