Resource Characteristics and Spatial Distribution of Old Trees in Coastal Areas of Central Zhejiang Province
摘要
Abstract
Old trees have important historical,ecological,economic,cultural and scientific research values.Studying the characteristics and spatial distribution of old trees in coastal areas of Central Zhejiang Prov-ince is of great significance for promoting the creation of old trees cultural parks,strengthening the protec-tion of old trees and promoting the construction of ecological civilization.Based on the survey results of old trees in Huangyan District of Taizhou City in 2018,a supplementary survey was conducted in 2023.The av-erage nearest neighbor index method and kernel density analysis method were used to analyze the resource characteristics of old trees,such as species,number of trees,protection level,and the spatial distribution of population,residential areas and topographic space.The results showed that there were 1 016 old trees in Huangyan,belonging to 29 families,49 genera and 64 species.The spatial distribution characteristics of old trees showed aggregation,and the spatial aggregation from high to low was in the east,southwest,south-central and northwest.The top four ancient tree density based on population are Fushan Township,Ping-tian Township,Shangzheng Township and Yutou Township.The average density was 118.73 plants/10 000 people,and the density value of Fushan Township was 188.03 plants/10 000 people.The total num-ber of old trees in the 100 m buffer range of the residential area accounted for more than 50％,and the pro-portion of old trees in the 500 m buffer range of the residential area exceeded 90％.The old trees are main-ly distributed in the range of 500 m above sea level,and the flat slope and low slope account for a large pro-portion.The old trees in the south and west are more than those in the north and east.The resources of old trees in the Huangyan District are abundant,and their spatial distribution characteristics show obvious spa-tial aggregation.They are mainly distributed in places with low altitude and slope,and are closely related to residential areas.关键词
