摘　　要：对厦门市古树名木资源现状和空间分布特征进行分析,旨在进一步掌握厦门市古树名木资源情况,为古树名木的保护和管理工作提供科学依据。研究基于2021~2023年厦门市古树名木调查数据,采用GIS信息技术与传统分析结合的方法,分析厦门市古树名木3项物种多样性指数,以及分布情况与行政区域、地形、坡度、坡向的关系。厦门市登记在册的古树名木共有1773株,其中名木、一级古树、二级古树、三级古树分别有11、68、319、1375株,隶属于27科39属43种;生长势正常的占比为82.18%,以本土树种为主,其中榕树数量最多。生物多样性Shannon-Wiener(H)指数为1.588,Pielou均匀度指数为0.420,Margalef丰富度指数5.882,生物多样性处于中等状态。厦门市古树名木最邻近比率为0.30<1,空间分布类型为聚集型;思明区鼓浪屿分布密度最高,超过26.9株·km^(-2);94.6%古树名木分布在坡度<15°地形上,各个坡向分布较为均匀;不同土地利用类型中古树名木占比最高的为居民及建设用地,达63.8%,其次为耕地,比例为29.9%。This study analyzed the current status and spatial distribution characteristics of ancient and famous trees in Xiamen City,with the aim of gaining a deeper understanding of the situation of these resources and providing a scientific basis for their protection and management.Based on data from the 2021 to 2023 survey of ancient and famous trees in Xiamen,the study employed a combination of GIS information technology and traditional analysis methods to examine three diversity indices of ancient and famous trees,as well as their distribution in relation to administrative regions,topography,slope,and aspect.Xiamen City has a total of 1773 ancient and famous trees registered in its records,including 11 famous trees,68 first-grade ancient trees,319 second-grade ancient trees,and 1375 third-grade ancient trees,belonging to 43 species of 39 genera in 27 families.The proportion of those with normal growth potential is 82.18%.The species are predominantly native,with banyan trees being the most numerous.The Shannon-Wiener(H)index for biodiversity is 1.588,the Pielou evenness index is 0.420,and the Margalef richness index is 5.882,indicating a moderate level of biodiversity.The nearest neighbor ratio for ancient and famous trees in Xiamen City is 0.30,which is less than 1,indicating a clustered spatial distribution type.The highest density is found in Gulangyu,Siming District,exceeding 26.9 trees per square kilometer.94.6%of these trees are located on slopes less than 15 degrees,and they are evenly distributed across various aspects.Among different land use types,residential and construction land has the highest proportion of ancient and famous trees,accounting for 63.8%,followed by farmland at 29.9%.
