Abstract Ulmus pumila is an important native tree species in Bashang region，which has both ecological and economic value.According to the climatic characteristics of Bashang region and the biological characteristics of Ulmus pumila，the pruning and tending techniques of Ulmus pumila windbreak and sand一fixing forests in Bashang region were summarized from the aspects of pruning object，pruning time，pruning intensity and pruning method.The investigation and monitoring of application examples showed that pruning and tending with reasonable strength could promote the growth of Ulmus pumila forest trees whileensuring the protectionfunction of forest stands，which is helpful to realize the multi-functional application of artificial sand-fixing forests.
