Yuanmou Gully erosion and collapse experimental station (Yuanmou station), is established both by Institute of Mountain Hazards and Environment, Chinese Academy of Sciences in Chengdu and Yunnan Academy of Agricultural Sciences for field observation and research. The station lies in Yuanmou dry-hot valley which is the representative area of southwest dry-hot valley, especially the Jinsha River dry-hot valley in China. The station was located in Julin town, Yuanmou city, Yunnan province, and was built in 1992. The area of experiment region is 40 ha, elevation is 1256 m～1331m, and the average slope is around 35%.  

The station presently has three schemed research directions: 

·   Mechanism of gully erosion and its impact on environment  

·   Ecosystem evolution and vegetation restoration in dry-hot valley ecosystem: 

·   Adaptive models of dry-hot valley ecosystem and its management
