- 摘要:
- 利用遥感、地理信息技术和数理统计方法，选择山西省吕梁市王家沟流域为典型区域，系统分析了半干旱黄土丘陵沟壑区沟道侵蚀特征。研究结果表明：在王家沟流域内共有沟道718条，其中冲沟109条，切沟286条，干沟302条及河沟21条。这4类沟道的发育特征和空间分布特征存在巨大差异；沟道侵蚀是王家沟流域内土壤侵蚀的主要形式，沟道侵蚀面积占总侵蚀面积的56.19%；流域内不同坡度范围内土壤侵蚀强度与沟道类型存在紧密联系。同时，人为因素也对黄土丘陵沟壑区的沟道侵蚀具有重要的影响。
- 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.
