Urban Forest is an important part of urban ecosystem.The green content of urban streets directly affects the ecological function of cities.This paper analyzes the present situation and construction potential of street forest in central city of Qujing,in order to find out the existing problems and laws,and to provide scientific basis for the construction and management of Forest City in Qujing.Based on Arcgis 10.7 and e Congnition Developer 9.0,we analyzed the tree canopy cover and urban forest structure in main streets of Zhanyi District.The canopy coverage of the southern section of Long-hua Avenue was the highest,reaching 40.22％.The canopy coverage rate of Xiping Road was the lowest,only 6.98％.A total of 45 species,22 families and 32 genera of the forest structure in 40 main streets were recorded.The importance value of Cinnamomum camphora in the dominant trees was 9.88％.The highest importance value of macrophylla in dominant shrubs was 12.49％.The dominant trees in the main streets of the central urban area had obvious dominance,and the fre-quency of other trees and plants made a balanced contribution to the important values.As a whole,the number distribu-tion of trees decreased with the increase of standing tree level,and the crown width of most trees was smaller.
