基于GIS的武安市古树名木空间分布及影响因素研究

Spatial Distribution and Influencing Factors of Ancient and Heritage Trees in Wu′an City Based on GIS

为进一步掌握河北省武安市古树资源以及影响古树名木分布的主要因素,对武安地区古树名木资源进行分析。以武安市1364株古树名木为试材,运用ArcGIS进行空间分布类型等可视化分析,结合周边环境因素对武安市古树名木进行空间分布特征及影响因素研究。结果表明,武安市古树名木呈集聚状态。古树名木生长与道路交通情况和距水源距离两因素间呈显著相关性,共同决定着武安市古树名木的空间分布特征。以期为全市古树名木保护、建设生态园林城市提供决策参考。

The ancient and heritage tree resources in Wu′an City of Hebei Province were analyzed to further grasp the resources status and the main factors affecting the distribution of ancient and heritage trees.Taking 1364 ancient and heritage trees in Wu′an City as test materials,the spatial distribution types and visualization analysis were carried out by using ArcGIS.Combined with the surrounding environmental factors,the spatial distribution characteristics and influencing factors of ancient and heritage trees were analyzed.The results showed that the ancient and heritage trees in Wu′an City were concentrated.The growth of ancient and heritage trees was significantly correlated with two factors of road traffic conditions and distance from water sources,which together determined the spatial distribution characteristics of ancient and heritage trees in Wu′an City.The results were to provide decision-making reference for the protection and construction of ecological garden cities with ancient and heritage trees throughout the city.
