Abstract: To better promote the protection of ancient banyan trees in Minhou County,based on the investigation and analysis of the characteristics of ancient banyan tree resources,this study explores the spatial distribution pattern and influencing factors of ancient banyan trees. By using tools such as Voronoi polygons and kernel density in ArcGIS,the spatial pattern and distribution characteristics of ancient banyan trees were reflected at a macro scale. The structural characteristics of ancient banyan tree resources were analyzed,and the driving mechanism of the spatial distribution of ancient banyan trees in Minhou County was explored using the Geodetector. There are 311 existing ancient banyan trees in Minhou County. The tree age structure shows a typical pyramid shape. There are 52 first-class ancient trees,97 second-class ancient trees and 162 third-class ancient trees. The average tree age is 330 years. The tree height,diameter at breast height and crown width are concentrated in the ranges of 10 ~ 25 m,100 ~ 250 cm and 10 ~ 30 m respectively. In terms of spatial distribution,it shows a significant aggregation state,forming four high-density concentration areas such as the junction of Hongwei Township and Baisha Town,and one sub-dense area at the junction of Shangjie Town and Nanyu Town. In terms of influencing factors,the ranking of factor explanatory power was as follows:road density > village density > altitude > water system buffer > slope > population density > land use type > aspect. The interaction among the factors shows a nonlinear enhancement. The resource structure characteristics of ancient banyan trees in Minhou County conform to the natural growth law. The driving mechanism of spatial distribution influencing factors shows the feature of " human-led and natural synergy" . Ancient banyan trees in low-altitude areas were more affected by human activities,while the distribution of ancient banyan trees in high-altitude areas was more dependent on natural conditions. This research provides a scientific basis for the protection of ancient banyan tree resources in Minhou County and is of great significance for promoting the inheritance and development of the local original ecological culture.
