高新技术产业开发区建设对城市空间形态演变的影响——以合肥市主城区为例

The Influence of the Development of High-tech Industrial Development Zones on the Evolution of Urban Spatial Structure:Taking the Main Urban Area in Hefei as an Example

基于等扇分析法、扩展强度指数、核密度分析法及平均最近邻分析法,探讨高新技术产业发展对城市空间形态演变的影响,结果表明:2000—2020年合肥市主城区高新技术产业呈“东北-西-东南”扩展的空间分布模式,合肥市建成区呈现显著的“东北-东南”和轻微的向西扩展的趋势,高新技术产业空间集聚格局由“一带、双核、两点”的空间集聚形态演化成“一主一副,连片发展”的空间格局,高新技术产业与城市建成区在空间上呈明显的高新区指向性,高新技术产业在推动城市范围扩大、城市空间形态演变和城市新核心的形成方面具有较大作用,研究为高新技术产业的布局及城市空间形态的优化提供一定的理论依据。

Based on equal fan analysis,extended intensity index,nuclear density analysis and average nearest neighbor analysis,this paper discusses the influence of high-tech industry development on urban spatial form evolution.The results show that:From 2000 to 2020,the high-tech industry in the urban area of Hefei presents a spatial distribution pattern of“northeast-west-southeast”expansion,and the expansion direction of the built-up area of Hefei is“southeast to northeast”.The spatial agglomeration pattern of high-tech industry has evolved from the spatial agglomeration pattern of“one belt,two cores and two points”to the spatial pattern of“one main and one pair,continuous development”.High-tech industries and urban built-up areas show obvious spatial orientation of high-tech zones,and high-tech industries play a significant role in promoting the expansion of urban scope,the evolution of urban spatial form and the formation of new urban cores.The study provides the theoretical basis for the layout of high-tech industries and the optimization of urban spatial form.
