中文摘要	金沙江干热河谷元谋盆地冲沟发育，冲沟侵蚀蚕食耕地、最终形成侵蚀劣地，对土地资源危害很大。根据对9条冲沟17个沟头连续3年的观测与调查资料，分析了元谋盆地土地利用／土地覆盖对冲沟侵蚀的影响，包括冲沟集水区不同土地利用方式、植被群落结构对冲沟溯源侵蚀的影响和沟底植被覆盖度对冲沟溯源侵蚀的影响。
英文摘要	Gully erosion, doing much harm to land resources by encroaching upon cropland, is well developed in Yuanmou Basin. The impacts of LUCC on Gully Erosion of Yuanmou Basin, including the impacts of different land use and community structure in gully watershed on headward erosion and the impacts of vegetation coverage on gully floor on headward erosion, were analyzed with the field-surveyed data of 17 gully heads in 9 gullies of successive 3 years. Results show that LUCC make a great impact on gully erosion, which can be reflected by the following aspects: (1) Different land use in gully watershed has an obvious impact on the speed of gully headward erosion, the fastest in bare land and the slowest in woodland. (2) The gully headward erosion of bare land and grassland in watershed has a positive correlation with rainfall. (3) Shrub-grass or tree-shrub-grass structure with a high coverage rate can effectively inhibit gully headward erosion in gully watershed and the simplex structure of grass or shrub is of less use. (4) The higher the vegetation coverage rate is on gully floor, the slower the gully headward erosion is.
