长三角地区特色小镇空间分布及其影响因素

Spatial Distribution and Influencing Factors of Characteristic Towns in the Yangtze River Delta

选取长三角地区376个特色小镇为研究对象,综合运用最邻近指数、核密度指数、缓冲区分析等GIS空间分析方法和地理集中指数、不均衡指数、地理联系率等数理分析方法探究其空间分布特征及影响因素,结果如下:(1)长三角地区特色小镇基于其主导产业可分为高端制造、信息经济、金融、创意时尚、传统产业、健康、历史经典、旅游8大类型,旅游类是该地区最主要的小镇类型;(2)长三角地区特色小镇空间分布不均衡,分布类型为集聚分布型;(3)长三角地区特色小镇分布密度核心区位于杭州市东北部,2个次级核心区分别是苏州市和嘉兴市,各类特色小镇分布密度核心存在分异;(4)自然因素包括地形条件、水文条件,人文因素包含经济与人口、创新能力、交通条件,二者共同影响长三角地区特色小镇空间分布。

376 characteristic towns in the Yangtze River Delta Region are selected as research objects in this study,Integrated use of GIS spatial analysis methods,such as the nearest point index,kernel density index,buffer analysis,and mathematical analysis methods like geographic concentration index,the index of unevenness,geographical connection rate to explore the spatial distribution characteristics and influencing factors,the results are as follows:(1)characteristic town based on its leading industries in Yangtze river delta can be divided into eight types,including high-end manufacturing,information economy,finance,creative fashion,traditional industry,health,historical classics,tourism,and tourism is the main type of town in this area;(2)The spatial distribution of characteristic towns in the Yangtze River Delta is unbalanced,and the distribution type is agglomeration distribution type;(3) The core area of the distribution density of characteristic towns in the Yangtze River Delta region is located in the northeast of Hangzhou,and the two secondary core areas are Suzhou and Jiaxing.The distribution density cores of different characteristic towns are different;(4) Natural factors,including elevation and topography,and human factors,including economy,population,transportation and innovation capacity,affecting the spatial distribution of characteristic towns in the Yangtze River Delta.
