摘　　要：基于城市流强度模型和改进的引力模型,从“等级-网络”双维度下的对外服务能力空间关系,开展福建省县级单元对外服务能力格局演变的分析。结果表明:(1)第二、三产业对外服务能力均持续增强的同时,工业与商务商贸成为职能部门的“双子星”。(2)对外服务能力空间格局整体表现出沿海高于内陆的特征,各职能分工定位与发展态势逐步明晰。(3)对外服务能力网络格局中第二、三产业勾勒出以沿海高等级联系为主导并向内陆辐射延展的放射状网络;工业职能部门在内陆与沿海分别形成倒“T”型与“钻石型”主干网络。Based on the urban flow intensity model and an improved gravity model,this paper analyzes the evolution of the spatial pattern of external service capacity of county-level units in Fujian Province from the spatial relationship of external service capacity under the dual dimensions of“hierarchy-network”.The results show that:(1)While the external service capacity of the secondary and tertiary industries continues to increase,industry and commerce have become the“twin stars”of functional departments.(2)The overall spatial pattern of external service capacity exhibits a characteristic where coastal areas surpass inland areas,with the division of labor and the development trends of each function becoming gradually clearer.(3)The network pattern of external service capacity in the secondary and tertiary industries outlines a radial network dominated by high-level coastal links extending inland;the industrial sector forms an inverted“T”-shaped and"diamond-shaped"backbone network in western Fujian and along the coast,respectively.
