2001—2019年武汉市土地供应格局的演化研究

Research on Evolution of Wuhan’s Land Supply Pattern from 2001 to 2019

基于2001—2019年的土地供应数据,借助地理空间统计方法,探究武汉土地供应格局的演化及其机理。结果表明:(1)土地供应数量以远城为主,供应类型以居住、工业、道路与交通运输用地为主,供应来源以新增建设用地为主,供应方式以划拨和出让为主;(2)土地供应规模呈先增后减态势,不断从主城向远城扩散,供应方向以东南向和西南向为主,各时段不同类型、不同方式、不同来源的土地供应在结构和空间上呈现出不同特征;(3)城镇与乡村发展、政府与市场互动、经济发展新常态化、中心与边缘异质性分别作用于土地供应,且4个方面相互关联共同驱动武汉土地供应格局演变。最后,基于土地供应格局演变提出土地高效供应的策略。

Based on land supply data from 2001 to 2019,this paper explores the evolution and mechanism of land supply pattern in Wuhan with the help of geospatial statistics.The conclusions are as follows:(1)The quantity of land supply is mainly in remote cities,the supply type is mainly residential,industrial,road,and transportation land,the supply source is mainly new construction land,and the supply method is mainly allocation and transfer.(2)The scale of land supply shows a trend of first increasing and then decreasing,continuously spreading from the main city to the distant city.The supply direction is mainly southeast and southwest,and different types,methods,and sources of land supply at different times show different structural and spatial characteristics.(3)Urban and rural development,government and market interaction,new normal of economic development,and center and edge heterogeneity respectively affect land supply,and the four aspects are interrelated to jointly drive the evolution of land supply pattern in Wuhan.Finally,strategies for efficient land supply are proposed based on the evolution of land supply patterns.
