摘要: 新时期我国国土空间规划战略的重要任务之一是实现土地资源最佳使用与紧凑城市发展战略，实现新型城镇化的高质量发展。紧凑城市作为国土空间规划的重要策略，对于解决中国快速城市化过程中城市蔓延带来的交通拥堵、资源浪费等城市问题具有重大意义。通过对上海市1995—2015年建成区的时空分析，挖掘建成区扩展演变规律。基于重力模型建立紧凑度指标对城市扩展过程进行量化分析，剖析紧凑度的时空演变规律：一是上海市建成区紧凑度先降低后升高，主城区紧凑度高于郊区；二是上海市主城区和郊区紧凑度变化受人口、产业、交通等多种因素的影响。面向国土空间规划时，提出紧凑城市发展策略及规划响应。
Abstract: One of the important tasks of China's territorial spatial planning strategy in the new era is to utilize land use properly and implement the compact city development strategy to achieve high-quality development for new-type urbanization. As an important strategy for territorial spatial planning, developing compact cities is of great significance for solving urban problems in China's rapid urbanization, such as traffic congestion and waste of resources induced by urban sprawl. This study explores the evolution of the built-up area through the spatio-temporal analysis of Shanghai from 1995 to 2015. Based on the gravity model, a compactness index system is examined to quantify the urban expansion process, and the spatio-temporal evolution of compactness is explored. First, the compactness of urban built-up areas in Shanghai declined and then increased, and the compactness of the main urban area is higher than that of the suburbs. Second, the compactness of Shanghai's main urban areas and suburbs is affected by various factors such as population, industry, and transportation. For territorial spatial planning, some measures of compact city development strategy and planning responses are proposed.
