Abstract:: Base on remote sensing techniques supported by GIS and other statistical methods, the feature of gully erosion in semiarid Loess Plateau was analyzed. The results showed that a total of 718 gullies were indentified in the Wangjiagou watershed, including 109 headwater gullies, 286 hillside gullies, 302 valleyside gullies and 21 ephemeral gullies. The four types of gullies have significant variables in the development characteristics and spatial distribution. Gully erosion is the major type of soil erosion in the Wangjiagou watershed, Which accounts for 56.19% of total area of soil erosion. There is a closed relationship between gully types and soil erosion intensity. Meanwhile,human factors have the significant impact on gully erosion in loess hilly area.
