基于地理大数据的休闲农业空间格局及其驱动因素研究——以京津冀为例

Research on the Spatial Pattern and Driving Factors of Recreational Agriculture Based on Geographic Big Data:Taking the Beijing-Tianjin-Hebei Region as an Example

基于休闲农业POI数据,运用最近邻指数、标准差椭圆、Ripley's K函数分析和核密度估计等方法,结合地理探测器模型,研究京津冀区域五类休闲农业的空间分布特征及其驱动因素,以期为京津冀地区休闲农业空间规划提供参考.结果表明:①京津冀休闲农业空间分布整体呈现比较明显的“一超多强”的多核心化趋势,且多集中在市中心邻近区域,向周围递减;②休闲度假类、回归自然类更加集中在以北京为中心的区域,农事体验类、农业科技类在相应的集聚区内呈现连片集聚,民俗文化类集聚峰值最小,分布较为分散;③经济发展水平、自然资源禀赋以及交通区位是影响休闲农业空间分布的主要驱动因素,不同因子交互作用均对空间集聚有所提升.

Based on the POI data of leisure agriculture,the nearest neighbor index,standard deviation ellipse,Ripley's K-function analysis and kernel density estimation and also by combining with the geographic detector model,the spatial distribution characteristics as well as driving factors of five types of leisure agriculture in the Beijing-Tianjin-Hebei region were studied in order to provide an important reference for the spatial planning of leisure agriculture in the Beijing-Tianjin-Hebei region.The results showed that:(1)the spatial distribution of leisure agriculture in the Beijing-Tianjin-Hebei region showed a relatively obvious multi-core trend of"one superpower and many powers",and most of them were concentrated in the adjacent areas of the city center,then the number decreased in the surrounding areas;(2)the types of leisure and vacation and returning to nature were more concentrated in the areas centered on Beijing,while the types of agricultural experience and agricultural science and technology were continuously clustered in the corresponding agglomeration areas.The peak of folk culture agglomeration was the smallest,and the distribution was relatively scattered;(3)economic development level,natural resource endowment and transportation location were the main driving factors affecting the spatial distribution of leisure agriculture,and spatial agglomeration was improved by the interaction of different factors.
