Abstract:: This paper select ecological restoration area in dry-hot valley as study object, soil moisture data of runoff plots in State Field Observation and Research Station of Debris Flow in Dongchuan, Yunnan Province, southwestern China was utilized, and then soil moisture of different land use, different depth and lag effect responds to rainfall was studied. The results show that: (1) The soil moisture was significant effected by Albizzia after ecological restoration in gravel soil, it could inhibit shallow landslide; pomegranate forest and transverse slope tillage and forest grassland could reduce slope runoff, so it could mitigation slope erosion after ecological restoration in hillside waste soil; (2) The soil moisture of different in 10 cm depth had large amplitude of changes and responded significantly to rainfall; and it had close correlations with the same day’s rainfall, the coefficient was above 0.35. The soil structure was improved in first stage of after ecological restoration, and then other biological species could live activities in this condition, so the ecological environment was improved.
