摘要
科学识别城市空间形态的演变特征,对把握城市空间发展脉络,科学划定城市开发边界,合理构建城市空间形态框架,保障城市健康可持续发展具有重要意义。本文以近年来发展迅速的昆明市呈贡区为研究对象,利用不同时期的高分遥感影像数据提取研究区土地利用信息,基于地统计和GIS技术对呈贡区的城市形态演变特征进行了定量分析。结果表明,呈贡区在过去15年中处于城镇化快速发展阶段;城市格局分化明显,西南和西北方向是主要的扩张方向,东南方向缓慢;自然因素极大地限制了呈贡区的扩张,而经济建设和政策规划的影响是城市用地扩张和时空演变的主要驱动因素。
Scientifically identifying the evolution characteristics of urban spatial form is of great significance for grasping the context of urban spatial development,scientifically delimiting urban development boundaries,rationally constructing urban spatial form framework,and ensuring the healthy and sustainable development of cities.This paper takes Chenggong,which has developed rapidly in recent years,as the research object,uses high-resolution remote sensing image data in different periods to extract land use information in the study area,and quantifies the urban morphological evolution characteristics of Chenggong based on Geostatistics and GIS technology.The results show that Chenggong has been in a stage of rapid urbanization development in the past 15 years;the urban pattern is clearly differentiated,the southwest and northwest are the main expansion directions,and the southeast is slow;natural factors greatly limit the expansion of Chenggong,while the impact of economic construction and policy planning is the main driver of urban land expansion and spatiotemporal evolution.
