Studying the phenological characteristics of landscape trees can determine the optimal afforestation time for local landscaping, while also providing a theoretical basis for garden design, plant configuration and garden phenology prediction. In order to grasp the leaf pheniological rhythm of common landscape tree species in Nyingchi Prefecture, optimize the garden plant configuration of Nyingchi Prefecture, 53 kinds of landscape tree species were selected as the object for continuous 5a parallel observation and analysis of their leaf phenology. The results showed that: the budding period lasts from early March to mid-April, and that of 20 species concentrates in late March. It is recommended that afforestation be completed before mid-April. The leaf expansion period lasts from early March to mid-June, and the peak period is from mid-April to early May. It is recommended to arrange the seasonal landscape according to the leaf expansion characteristics of the tree species. The 53 tree species were classified into 5 types based on leaf phenological characteristics. Finally, corresponding measures and suggestions were proposed for local garden afforestation and tree arrangement.
