行业分类下武汉市工业用地时空演变分析

基于2010～2018年武汉市工业用地出让数据,借助GIS技术,综合运用空间自相关分析、核密度分析和区位熵等方法,在研究武汉市工业用地总体格局的基础上,探讨了其时空演变的整体特征和行业特征。结果表明:(1)武汉市出让工业用地空间分布的近郊区指向性明显,且在研究区域内呈现环状集聚的特征;(2)2010～2018年武汉市出让工业用地整体规模呈下降趋势,出让重心沿"东北-西南"方向转移,且空间变化呈现由内城区到近郊区的集聚变动趋势;(3)行业分类下,工业用地受让单位以加工工业为主,但随时间变化,主导产业由加工工业演变为高新技术工业,且不同行业空间布局存在差异:食品轻纺业在内城区和远郊区具有分布优势;加工工业和原材料工业趋向于近郊区分布;高新技术工业主要集中在大光谷工业板块;工业配套生产生活服务业多布局在人力和产业集聚区;电力、热力、燃气及水生产和供应业在城市郊区零散分布。

Analysis on Spatial and Temporal Evolution of Industrial Land Under Industry Classification in Wuhan City

Based on the data of industrial land transfer in Wuhan City from 2010 to 2018, the paper discussed the general and industrial characteristics of spatial and temporal evolution on industrial land of Wuhan with the help of GIS technology, Moran I analysis, kernel density analysis, location quotient and other methods on the basis of studying the overall pattern of industrial land in Wuhan. The results show that: (1) the near suburb area where the transferred wuhan industrial land space are located has an obvious directivity, and is circular agglomerated within the research area.(2) From 2010 to 2018, the overall scale of the transferred wuhan industrial land showed a downward trend, with the core area shifted from the northeast to the southwest, and the spatial change showed a trend of agglomeration from inner urban areas to suburbs. (3)under the industry classification, the transfer unit of industrial land is mainly processing industry, but with time, the leading industry has evolved from the processing industry to the high tech industry, and the spatial layout of different industries is different: Food textile industry has the distribution advantage in inner city and far suburbs；Processing industry and raw material industry tend to be distributed in the suburbs; High tech industry is mainly concentrated in the Optics valley industrial sector; Industrial supporting production and life services is mostly distributed in human and industrial agglomeration areas. Electricity, heat, gas, water production and supply are scattered in the suburbs.
