南宁市主城区城镇化时空演变特征研究

Study on the Spatiotemporal Evolution Characteristics of Urbanization in the Main Urban Area of Nanning City

基于2000、2005、2010、2015、2020年5期土地覆盖数据,通过城镇扩展速度、扩展强度、扩展动态度和面积变化度等城市变化监测指数以及雷达图等形式,呈现出南宁市主城区城镇化时空演变特征,并分析其驱动因素,旨在找到城镇化发展的关键,为研究和解决城镇化问题提供参考,从而以更加有效的方式加速推进广西其他城市城镇化进程。

Based on the land cover data of five periods in 2000,2005,2010,2015 and 2020,the spatial-temporal evolution characteristics of urbanization in the main urban area of Nanning City are presented through urban change monitoring indexes such as urban expansion speed,expansion intensity,expansion dynamics and area change,as well as radar charts,and its driving factors are analyzed.The aim is to find the key to urbanization development,provide reference for researching and solving urbanization problems,and accelerate the urbanization process of other cities in Guangxi in a more effective way.
