摘　　要：基于改进的引力模型,研究识别了武汉城市圈经济联系空间特征,并与规划进行了验证分析。研究表明:①武汉城市圈经济联系单中心集聚明显,“核心-近域-外围”3个层次的武汉大都市区格局已显雏形。②武汉沿“鄂孝黄黄”轴线联系显著,与咸宁、天门和潜江联系较弱;东湖高新区、东西湖区与周边区县经济联系强劲。③武汉外,鄂州和黄石间存在较强的经济联系,仙桃、天门和潜江存在独立的三角联系。Based on the improved gravity model,this paper identified the spatial distribution of the economic interconnections in Wuhan metropolitan area and verified with the planning.The results show that:First,the economic interconnections of Wuhan metropolitan area obviously concentrated to Wuhan as one single center,and it has formed a spatial pattern of“Core-Near region-Periphery”.Second,Wuhan has a significant connection along the axis of“E-Xiao-Huang-Huang”,while the contact with Xianning,Tianmen and Qianjiang is weak,and there are strong economic ties between Wuhan East Lake High-tech Development Zone,Dongxihu District and surrounding counties.Finally,outside Wuhan,Ezhou and Huangshi have strong economic ties,while Xiantao,Tianmen and Qianjiang have independent triangular ties.
