Abstract

The purpose of this study was to explore the species composition,individual number,source,age structure and distribution of ancient trees in Yubei District of Chongqing,and the impact of land use type change on ancient trees,so as to highlight the value of ancient trees in inheriting history and culture,improve urban environment and protect regional biodiversity. Based on the existing data of ancient trees,this study conducted a field survey of ancient trees in Yubei District from March to June in 2021,and supplemented some data. Excel,ArcGIS,Spss Statistics 25 and other software were used to analyze the grade,family,species composition and growth of ancient trees in Yubei District. The spatial distribution characteristics were summarized,and the land use types were divided in Yubei District. The change of land use types was studied,and the influence of land use type change on ancient trees was revealed. The results showed that the rapid urbanization made the ancient trees face the problems of habitat deterioration and narrow growth and development space,and most of the preserved ancient trees in the highly urbanized area were the trees with strong adaptability. On this basis,the targeted conservation strategies of ancient trees were put forward.

Key words： Yubei District; ancient trees; spatial distribution; land use type; protection countermeasures
