广东省古树资源分布及文化要素研究

通过分析广东省古树资源的组成与分布特征，研究影响其分布格局的文化要素。结果表明，古树组成种类集中，榕树、樟树、枫香、荔枝和龙眼5种古树占总株数的55.40%；总体树龄偏低，三级古树占93.07%。古树分布山区多，滨海少；村落古树数量远多于城市；历史名城古树数量普遍高于新城；风水林、公园景区、寺庙宗祠和学校等文化空间是古树的集中分布点。古树的组成与分布特征除了受到自然条件的约束，更受到农业种植文化、植物个体文化、风水林文化、宗教与宗祠文化、开发与迁移文化等要素影响。这些古树文化既是古树组成与分布的重要成因，也是古树保护与利用的价值所在。基于资源分布及文化要素出发的举措应该成为古树资源保护与利用的新路径。

Resource Distribution and Culture Elements of Ancient Trees in Guangdong Province

The composition and distribution characteristics of ancient trees occurring in Guangdong Province were studied through field investigation and literature research to understand the cultural influence and the value of ancient trees.The results indicated that the types of ancient trees were concentrated in several species,such as Ficus microcarpa,Cinnamomum camphora,Liquidambar formosana,Litchi chinensis and Dimocarpus longan,accounting for 55.40% of the total number.The overall tree age was relatively low,93.07% ancient trees were between 100 to 299 years old.In terms of space distribution,ancient trees are mainly distributed in north part and mountain region of the province,growing in villages,parks,temples and schools,In addition to the natural environment,the number and distribution of ancient trees in the province are influenced by the development history,plant culture,religious culture,Fengshui forest culture,and population migration culture.These culture elements are not only important contributing factors of the composition and distribution of ancient trees,but also the value of ancient tree protection and utilization.Measures based on the distribution of resources and cultural elements should become a new way for the protection and utilization of ancient tree resources.
