摘要:
旨在充分认识东北典型黑土漫岗区切沟分布的空间特征，为水土保持工作提供依据，以黑龙江省宾县漫岗区为研究区，结合实地调查，以SPOT 5遥感影像为数据源，基于人机交互方式提取切沟信息，并分析其分布特征。主要研究结论如下：5°；～7°；的漫岗坡面更易形成切沟侵蚀；切沟密度随海拔高度的增加呈现出先迅速上升后缓慢下降的趋势，在坡面的中下部更易发生切沟侵蚀；由于地理位置及地貌特征、土地利用方式、开垦时间早晚和治理措施等不同，研究区不同乡镇的切沟密度存在着较大差异。
Abstract:
For fully understanding the spatial characteristics of gully erosion distribution over typical black hilly region of Northeast China and providing the basis for the conservation of water and soil work, this paper selected the hilly areas of Bin Country of Heilongjiang Province as the study area, took the SPOT5 remote sensing images as the data source, got the information of gully based on man-machine interaction, and analyzed the spatial pattern of the gully. The main conclusions were as follows: it was easier to form a hilly slope gully erosion on 5°~7° of the hilly slope; gully density showed the trend of slow decline after the first rapid rise accompanying the increasing of altitude, it was easier to form a hilly slope gully erosion in the middle and lower slopes; there was a big difference of gully density in different towns because of the differences on location and topographic feature, land use, sooner or later cultivation time and control measures.
