南京市休闲农业景点时空分布特征分析

Research on Characteristics of Spatial and Temporal Distribution of Nanjing Agritourism Scenic Spots

选取南京市2011年评定的172个休闲农业星级景点作为样本,并通过ArcGIS进行可视化表达,采用季节性强度指数、季节指数、最近邻指数、基尼系数、核密度估计法等方法对南京休闲农业景点的时间、空间分布状况进行分析.结果表明:从时间分布上来看,近年来南京休闲农业景点数量逐年增加,并且等级不断提高,产品层次逐步提升,客流季节性明显;从空间分布上看,南京休闲农业景点呈凝聚型,在各郊区县的分布不均衡,其中江宁区分布数量最多,密度最大,而雨花台区与栖霞区数量最少.

Selecting the 172 agritourism scenic spots in Nanjing which were star-rated in 2011 as samples, this paper uses the visualization representation of Arcgis software, Seasonal intensity index, Seasonal index, Gini coefficient, and the Kernel density estimation method to analyze the spatial and temporal distribution of Nanjing agritourism scenic spots. The result shows that：from the view of temporal distribution,the quantity of Nanjing agritourism scenic spots increases every year,rates of these scenic spots upgrads continuously, and the level of the agritourism product improved guadually, besides ,the tourist flow has obvious seasonal characteristics. From the view of spatial distribution, Naujing agritourism scenic spots shows an agglomerative distribution, and has a unbalanced distribution in different suburban counties, the county which has the largest quantity and density of agritourism scenic spots in Nanjing is Jiangning county, while the smallest two are Yuhuatai county and Qixia county.
