摘要
我国城镇化处于后期增速放缓及质量提升阶段,城市增长方式逐步从“增量发展”向“存量提质”过渡,进入城市更新的城镇化新模式。城市更新作为城市国土空间全域范围内持续完善功能、优化空间布局、提升环境品质、激发经济社会活力的空间治理活动,地理空间信息正在其中发挥重要的技术和思维支撑作用。本文在“生产空间”、“生活空间”、“生态空间”(简称“三生空间”)视角下,重新审视了城市更新的内涵,指出城市更新本质上是对“三生空间”的统筹优化。基于“城市认知”中的感知、评估和优化等全过程,构建了“三生空间”视角下的城市更新逻辑架构,并基于此架构梳理了地理空间信息技术在“三生空间”中要素感知、效益评估和空间优化方面的应用与研究现状。立足城市更新实际需求,基于现代地理空间信息技术,通过对城市的综合感知、综合评估和综合优化,提出构建涵盖“感知-评估-优化”城市认知全过程的全空间城市更新技术体系,以提高城市适应未来发展的自我调控能力,实现国土空间治理体系和治理能力现代化。
In China,urbanization has entered a later stage characterized by a slowdown in growth rates and a focus on quality enhancement.The urban growth paradigm is transitioning gradually from"incremental development"to"quality improvement of existing urban stock",marking the adoption of a new urbanization mode centered around urban renewal.Urban renewal,as a spatial governance activity within the scope of national territory,aims to continuously enhance city functions,optimize spatial layout,improve environmental quality,and stimulate economic and social vitality.However,challenges of urban renewal,such as the ambiguous definition of urban renewal oriented towards national spatial planning and the lack of a systematic logical framework for geographic information technology tailored for urban renewal,still persist.Therefore,this study reexamines the connotations of urban renewal research from the perspective of the"Production-Living-Ecological"space,expecting to achieve"intensive and efficient production space","livable and moderate living space",and"beautiful and ecofriendly ecological space".Furthermore,with reference to the three processes of perception,assessment and optimization in"Urban Cognition",the logical architecture of geospatial information technology application for urban renewal is constructed,and based on this framework,the contributions of geographic spatial information technology in data collection,model assessment,and simulation optimization are elucidated.In the production space,geospatial information technology is able to perceive the production elements of urban renewal in real time,rapidly construct the economic benefit assessment index system and spatial assessment model,simulate the geographical process of industrial development,and optimize the spatial pattern of production.In the living space, the application of geospatial information technology helps to integrate the resources of living elements bymeans of spatial and temporal digitization, comprehensively assess the social benefits and carry o
