Abstract: (1) The dry valley area of the Bailong River is a typical ecological fragile area.Its ecological environment degradation is serious,and its vegetation restoration is difficult.(2) Through the analysis of the current situation of the dry valley in the Bailong River,the ecological composition,structure and spatial pattern of the area were summarized.It is found that there are still many deficiencies in the protection of vegetation and regional characteristics,and it is believed that the future research work should be strengthened in many aspects,such as degradation mechanism,human disturbance,fragile ecological environment and so on.(3) Analysis is made of the causes of degradation,aiming to find out the adaptation of the local tree species and development models and to provide reference for vegetation restoration and ecological environment research in the Bailong River dry valley.
