Based on the investigation of the current situation of ancient and famous trees in Mangshi City,and the analysis of the resource characteristics,spatial distribution pattern and growth status of ancient and famous trees,the results show that there are 1028 ancient and famous trees in Mangshi area,belonging to 32 species,23 genera,17 families.Taking local tree species such as Ficus altissima as the main dominant species,the age of trees is pyramid structure,and the spatial distribution is a pattern of gathering in the central urban area and gradually radiating around.Human activities have little impact on ancient trees.There is a strong correlation(p=-0.959)between the altitude and the number of ancient trees.There is a nonlinear positive correlation among DBH(mainly Ficus altissima),crown diameter and tree height,and the increase of tree age will not affect the appearance and growth of tree species.The ancient and famous trees resources in the suburbs will become the focus of protection for the management departments in the future.The study comprehensively analyzed the status of ancient tree resources in the city from various perspectives,which can provide reference for the protection of ancient and famous trees.
