The Dry-hot Valley of the Jinsha River in southwest China is an ecologically fragile zone in which gully erosion is one of the most important environmental problems due to the high sediment yield from the gully. The aim of this study was to investigate the vegetation conditions in conjunction with the topography and the soil conditions in the gully and to analyse the distribution of vegetation in different parts of the gully. The vegetation indices, in addition to the soil conditions and topography, were measured through field investigations and the gully Digital Elevation Model (DEM). It is highlighted that the vegetation in the gully is not only impacted by the soil and the topography in the area of vegetation growth but also influenced by the runoff processes upstream of the gully heads
