Abstract:

In order to explore the characteristics of ancient tree resources,the types of spatial distribution and the factors affecting their distribution characteristics,it is better to serve the urban and rural ecological environment and the construction of beautiful villages.Taking the ancient tree resources in Liaocheng City as an example,through the fishing net analysis and nuclear density analysis in ArcGIS,the spatial distribution type and distribution density of ancient tree resources were studied,and the land cover type and population density was analyzed.The influence of traditional villages and ancient tree culture on the distribution of ancient trees.The results showed that there were 687 ancient trees in Liaocheng City,including 65 first-class ancient trees,79 second-class ancient trees and 543 third-class ancient trees.The dominant species were Platycladusorientalis,Styphnolobium japonicum and Ziziphus jujuba.The tree height,DBH and crown width were concentrated in >10.0~15.0 m,<1.0 m,>5.0~10.0 m,respectively.The number of normal plants accounted for 71.47 % of the total number of plants,and the number of weak plants accounted for 23.73 % of the total number of plants;the spatial distribution type of ancient trees was aggregated distribution,including 1 high-density area and 6 sub-density areas.The overall distribution pattern of ancient trees was “more in the south and less in the north”,“scattered and multi-group”.Through the research and analysis,it is expected to provide reference for the management and protection of ancient trees in Liaocheng City,and provide decision-making basis for the construction of beautiful villages.

Key words: Liaocheng City, ancient tree resources, spatial distribution, feature analysis
