摘要
选取江苏省45 个县域单元,通过行政区驻地以及土地利用遥感数据对各县域的城区进行划定,基于医疗、教育、休闲、交通、餐饮、金融6 类公共服务设施的POI数据,运用核密度比值、标准差椭圆、香农多样性指数、可达性分析及熵值法等对江苏省县城的公共服务设施配置能力进行评价.结果表明:(1)县域6 类公共服务设施中教育设施配置最为分散,餐饮设施配置最为集中;(2)北部地区县城在县域范围的公共服务设施集聚效应更强;(3)县城内部公共服务设施的功能混合度高值区分布较为集中;(4)县城各类公共服务设施配置水平南高北低,分布类型具有地域差异,与经济发展水平相吻合.
Abstract
Selecting 45 county-level units in Jiangsu Province,the urban areas of each county were delineated through administrative districts and land use remote sensing data.Based on POI data of six types of public service facilities including medical,education,leisure,transportation,catering,and finance,the public service facility al-location capacity of county towns in Jiangsu Province was evaluated using kernel density ratio,standard deviation ellipse,Shannon diversity index,accessibility analysis,and entropy method.The results show that:(1)Among the six types of public service facilities in the county,the configuration of educational facilities is the most scat-tered,and the configuration of catering facilities is the most concentrated;(2)The agglomeration effect of public service facilities in counties in the northern region is stronger;(3)The distribution of high-value areas with mixed functions of public service facilities within the county town is relatively concentrated;(4)The configuration level of various public service facilities in the county town is high in the south and low in the north,with regional differ-ences in distribution types that are consistent with the level of economic development.
