摘要:

为系统掌握湖州市古树资源本底与空间分布规律,支撑古树精准保护与生态网络融合,基于2023—2024年湖州市全域古树调查数据,采用ArcGIS核密度分析与空间叠置法,分析树种组成、树龄结构、区域分布及与生态源地的耦合特征。结果表明:湖州市共有古树8934株,隶属于40科81属111种,数量达100株以上的优势树种13种,其中枫香(1019株)、银杏(4691株)数量较多,两者占比63.91%。从树龄结构看,一级古树185株,占2.07%,其中树龄高于1000年的古树35株,仅占比0.39%,分别为柏树、榧树、黄连木、罗汉松、南方红豆杉、银杏、圆柏、重阳木等8种;二级古树469株32种,占5.25%;三级古树8280株,占92.68%,种类涵盖了所有古树树种。古树主要分布于长兴县(48.29%)、安吉县(36.82%),不同区县呈现出显著性差异。古树空间分布呈现分散、多组团集聚的格局,与湖州市生态保护、自然保护地进行叠加,6.02%位于生态源地、10.85%远离生态源地。研究认为,湖州古树资源丰富、区域分异明显、与生态网络空间耦合度不足。建议构建分级分类保护体系,强化生态空间连通性,推动古树保护与文化旅游、乡村振兴深度融合。本研究可为长三角低山丘陵区古树资源保护与生态网络优化提供科学依据,未来可结合长期监测与数字孪生技术实现智慧管护。

Abstract:

The study aims to systematically grasp the background and spatial distribution of ancient tree resources in Huzhou City, and support the precise protection of ancient trees and the integration of ecological networks. Based on the survey data of ancient trees in Huzhou City from 2023 to 2024, ArcGIS kernel density analysis and spatial overlay method were used to analyze the tree species composition, tree age structure, regional distribution and coupling characteristics with ecological sources. The results showed that a total of 8934 ancient trees were recorded, belonging to 40 families, 81 genera and 111 species. Among these,13 dominant species had more than 100 individuals each. Liquidambar formosana (1019 trees) and Ginkgo biloba (4691 trees) were the most abundant accounting for 63.91%. There were 185 first-class ancient trees (2.07%), including 35 trees over 1000 years old (0.39%) from 8 species (Platycladus orientalis, Torreya grandis, Pistacia chinensis, Podocarpus macrophyllus, Taxus mairei, Ginkgo biloba, Sabina chinensis and Bischofia Polycarpa). Second-class ancient trees numbered 469 (5.25%) and covered 32 species,while third-class ancient trees accounted for 8280 (92.68%) and included all species. The ancient trees were mainly distributed in Changxing County (48.29%) and Anji County (36.82%), showing significant differences in counties. The spatial distribution of ancient trees showed scattered and multi-group agglomeration. Superimposed with the ecological protection and natural protection areas, there were 6.02% located in and 10.85% far away. In summary, Huzhou ancient tree resources are rich, regional differences are obvious, and the coupling degree with ecological network space is insufficient. Accordingly, it is recommended to establish a fine protection system, strengthen the connectivity of ecological spaces, and promote the deep integration of ancient tree protection with cultural tourism and rural revitalization. This study provides a scientific basis for the protection of ancient tree resources and the optimization of ecological networks in the hilly areas of the Yangtze River Delta. In the future, long-term monitoring and digital twin technology can be combined to achieve intelligent management and protection.
