基于ESDA-GIS的广东省城乡统筹发展空间分异

基于2010年广东省21个地级市城乡统筹发展统计数据,借助GIS、GeoDA软件,运用ESDA-GIS空间分析方法,对广东省城乡统筹发展水平和空间分异格局进行研究。结果表明：广东省城乡统筹发展水平空间差异明显,形成了明显的空间二元结构,呈现出以穗—莞—深为核心向外围地区逐渐递减的发展趋势,东西两翼以及粤北地区城乡统筹发展水平较差,珠三角经济区东部地区城乡统筹整合速度快,辐射能力强;根据综合水平与其空间滞后值的组合关系,将广东省城乡统筹发展划分为3种地域类型,即高水平均质型地域类型、塌陷型地域类型以及低水平均质型地域类型;全省城市化水平与城乡统筹的发展程度并不完全匹配,这要求各地市在实际制定政策过程中,应通过差别化分类型政策的制定来促进城乡统筹发展。

Spatial Difference of Urban and Rural Harmonious Development with ESDA-GIS Framework in Guangdong Province

Based on the Urban and Rural Harmonious statistical data of Guangdong’s 21 cities in 2010,supported by the ESDA-GIS spatial framework,this paper analysis the development level and spatial difference of Urban and Rural Harmonious in Guangdong province.The result illustrates that,there is significant level differentiation of urban and rural harmonious in Guangdong,existing an obvious dual-spatial structure,spatial patterns of urban and rural harmonious showed up in Guangzhou-Dongguan-Shenzhen line are the highest,gradually decreasing from center to the surrounding.Urban and Rural Harmonious development level is poor in the northern and the east and west wings of Guangdong province.The integration speed of urban and rural harmonious is fast in the east of Pearl River Delta Economic Zone,and the ability of radiation are strong;According to the combination relations of comprehensive capacity and its spatial lagging,urban and rural harmonious development in Guangdong province should be divided into three kinds of regional types,namely high level and equally regional type,type of collapse,and a lower level and equally of regional type;The urbanization with urban and rural harmonious development degree is not exactly match,this requires all city in the actual policy process,and should through make regional differentiation policy formulation to promote the urban and rural harmonious development.
