Abstract:

In order to quantitatively evaluate the canopy structure of urban garden plant community, a study on canopy structure of typical landscape plant communities in Chengdu was conducted by using WinScanopy for Hemispherical Image Analysis. The results showed that there was significant difference on the canopy structure of plant communities among all sample plots. The range of LAI, general porosity, total opening and canopy density were 0.07-2.61, 13.61%-95.81%, 14.32%-88.3% and 11.71%-85.68%, respectively. The distribution pattern of average leaf angle changed from acute angle (14.76°) to close to right angle (82.44°). The results would contribute to the quantitative evaluation on the spatial structure of urban garden plant community and provide scientific basis for the community collocation and landscape design in urban garden plant community.
