江苏省水利风景区时空演变及其影响因素

Spatiotemporal Evolution and Influence Factors of Water Parks in Jiangsu Province

基于2001—2016年面板数据,运用GIS空间分析技术,从时空维度分析了江苏省水利风景区的演变特征及其影响因素。结果显示:(1)从时间维度看,江苏省水利风景区的发展阶段可分为稳步推进期(2001—2006年)、加快发展期(2007—2010年)、快速增长期(2011—2016年)三个阶段;景区类型不断丰富,但不同类型之间发展差异较大。(2)从空间维度看,江苏省水利风景区总体上呈现'西北—东南'分布格局,分布平均中心先自南向北迁移,后自北向南略有回归;市际尺度上呈集中分布的态势,但集中程度逐渐下降;空间关联上,景区分布整体上呈现一定的空间正相关,局部空间自相关显著的区域包括H-H型、H-L型、L-H型三种类型,局部空间格局变化较大。(3)江苏省水利风景区时空演变主要受资源、交通、市场、政策等因素的影响。

Based on the panel data from 2001 to 2016, this paper analyzes the evolution characters and influence factors of water parks in Jiangsu Province by GIS spatial analysis technology from time and space dimensions. The results show that:(1) The development of water parks in Jiangsu Province can be divided into 3 stages: steady promotion period(2001-2006), accelerated development period(2007-2010) and rapid growth period(2011-2016) on temporal scale. The types of water parks increase over time, but the differences between various types are obvious.(2) The water parks in Jiangsu Province show the distribution pattern of"northwest-southeast". The average distribution center first migrated from south to north, then returned slightly from north to south. The water parks are centrally distributed on the intercity scale, but the concentration degree is decreasing. In terms of spatial correlation, the distribution of water parks shows a certain spatial positive correlation on the whole. The regions with significant local spatial autocorrelation include three types: H-H, H-L and L-H, and the local spatial patterns have changed greatly.(3) The spatiotemporal evolution of water parks in Jiangsu Province is mainly influenced by resources, traffic, market and policy.
