A large area of water-level-fluctuating zone will be emerged after the completion of the reservoir engineering of dry-hot valleys in the Jinsha River.This paper presents that using vetiver and integrated engineering technology may prevent some problems from probably appearing in the water-level-fluctuating zone,such as soil and water loss,water pollution,and damages to the ecological system.The likelihood of existed ecological environment problems and the characteristics of vetiver and its functions are briefly introduced.In addition,the program of ecological restoration for the water-level-fluctuating zone is proposed.It is expected that a sustainable ecological system may be established.
