基于皖江城市带46个评价单元面板数据,运用综合区位熵、产业区位熵平均绝对差、耦合关系等系列模型,借助GIS空间与属性关联功能,剖析区县主要产业及产业集聚度的空间分异,以及产业集聚度与产业用地效益的空间耦合。研究表明:木材家具业、农副加工业、纺织服装业作为最多区域的主要产业,分别达到26个、25个、24个,反映整个区域还是以低初级产业类型为主;产业集聚程度较高的区域集中于西北部大别山区、偏远县域范围,而市区及城镇产业发达区域产业集聚表现不突出;产业用地效益数值区域差异很大,较高区域主要集中沿江城镇发展轴及合肥省会都市圈区域,较小区域集中分布于原料导向型、劳动导向型为主;耦合程度基本呈现版块化结构,皖江城市带东南部高于西北部,从东到西呈现递减趋势,并将整个区域划分为高度耦合型、中度耦合型、轻度耦合型、极不耦合型等四大耦合类型区。
Based on the panel data of 46 evaluation units in Wanjiang city belt, this paper analyzes the spatial distribution of major industry and industrial agglomeration in districts and counties by means of GIS spatial and attribute related functions by using a series of models such as comprehensive location entropy, average absolute entropy of industrial location entropy, and coupling relations Different, as well as the spatial coupling of industrial concentration and industrial land efficiency. The research shows that the main industries of wood furniture industry, agricultural and sideline processing industry and textile and garment industry as the largest areas reach 26, 25 and 24, respectively, reflecting the whole region as the main types of low-grade industries; the higher degree of industrial agglomeration Are concentrated in the Dabie Mountains in the northwestern part of China and in remote areas. However, the performance of industrial agglomeration in developed areas of urban and urban areas is not conspicuous. The numerical value of industrial land use benefits varies greatly. The higher areas mainly focus on the axis of urban development along the Yangtze River and the metropolitan area of Hefei The area and the smaller area are mainly distributed in the material-oriented and labor-oriented types. The degree of coupling is basically a plate-shaped structure. The southeastern part of Wanjiang City is higher than that in the northwest and presents a decreasing trend from east to west, and the whole area is divided For the highly coupled, moderately coupled, slightly coupled, very uncoupled and other four major types of coupling area.
