浙江省滨海城镇带的中心—边界识别
|
摘要
浙江滨海城镇带是浙江经济、产业、城市化发展的核心区,主导未来浙江城镇体系的发展演化。基于加权Voronoi图像,结合城镇综合辐射指数计算与断裂点模型,构建城镇辐射区模型,划分浙江滨海城镇带辐射范围。研究表明:1滨海城镇带总体辐射能力较强,呈现出"三片四点"的空间格局,中心—边界体系结构清晰;2部分边界地区仍存在弱连绵区或单一强辐射扩张的现象,城镇空间发展不均衡。根据滨海城镇带中心—边界发展态势,提出滨海城镇带的后续空间演化模式"板块都市圈培育发展—分区城市群形成—滨海城市带形成"的构想。
Coastal city-and-town concentration areas is the core area of economy, industry and urbanization development in Zhejiang, leading the development and evolution of urban system in the future. Based on weighted Voronoi, combining urban comprehensive efficiency index and breaking point model, urban areas of radiation model was constructed, Coastal city-and-town concentration areas is divided and classified by this model. Study shows:(1) Coastal city-and-town concentration areas has strong influence, showing a "Three block Four point" urban spatial pattern. Center-boundary structure is clear.(2) Urban spatial development is not balanced. Part of the boundary region still exist weakly continuous area and single strong radiation expansion. Based on trend of development of center-boundary structure, paper proposed that concept of spatial evolution patterns "The development stage of the cultivation and development of plate metropolitan area-Stage of block urban agglomeration-Stage of coastal city zone" was used in coastal city-and-town concentration areas.
