面向国土空间规划的城市引力模型研究OACSTPCD

To meet the needs of urban agglomeration spatial planning and implementation supervision and evaluation,based on the traditional ur-ban gravity model,we added some territorial spatial factors,such as the area and proportion of transportation land,network density of built-up ar-ea,green ratio of built-up area,network density of railway and highway and the minimum transit time of railway and highway traffic etc.Then,we constructed an urban gravity model based on the perspective of territorial spatial planning,and carried out the urban correlation degree calcu-lation and change characteristics analysis of Hubei urban agglomerations in 2018 and 2019.The experimental results show that the urban correla-tion between Wuhan and Xiantao,Tianmen,Qianjiang increases rapidly and the situation between Xiantao and Tianmen,Xiaogan is the same.The urban correlation between Suizhou and Xiangyang,Shiyan grows faster,while that between Shennongjia and Xiangyang,Shiyan grows slow-er.The urban correlation between Jingzhou and Jingmen,Yichang increases rapidly,while that between Enshi and Jingzhou,Jingmen grows slow-ly.Each city should formulate its urban development strategy according to the urban actual situation of quality index and distance index.
