摘要
采用GPS野外定点测量的方法,对东北黑土区鹤北小流域切沟长度进行了调查,经室内Arcinfo处理及统计分析,获取了鹤北流域沟长特征及其与道路状况的关系。研究结果表明:(1)从数量关系看,鹤北流域道路长度与切沟长度存在一定关系,表现在土质路面的道路对切沟影响较大;流域谷底和坡面下部道路长度与切沟长度关系最密切。(2)鹤北小流域切沟分布与道路分布关系密切,道路两侧约25 m范围内切沟长度增长迅速,是治理的重点区域。
Through field GPS surveying and dealing with the data that got from field,the relationships between gully length and road length as well as the characteristics of gullies in different buffers with different radius of road in Hebei small watershed of Northestern China were analyzed.The following conclusions were acquired：（1） the quantitative relation suggested a relationship between road length and gully length existed,especially in valley and the lower slope,unpaved road and gully length had a strong relationship.（2） Gully distribution was closely related with road distribution.The buffer of road winth the range of 25 meters was the most risky area where gully easily happened,so road was an important factor for affecting gully happening.
