延吉城市功能空间演化及驱动力分析

Analysis of the Urban Spatial Structural Evolution and Driving Forces of Yanji City Based on GIS

运用探索性空间数据分析(ESDA)方法,基于GIS平台并借助多源遥感影像及土地利用图,定量分析了延吉市1999-2010年城市功能空间结构的演化,提出延吉市应采用精明增长模式,主城区应继续采用T字形空间发展战略,以增强西部卫星城———朝阳川镇的独立性。

It quantitatively analyzed the evolution of urban spatial structure of Yanji City from 1999 to 2010.The analysis was made by means of the exploratory spatial data analysis （ESDA） with the platform of GIS as well as the application of basic data of multisource remote sensing image and land use maps.On this basis, a suggestion was put forward that Yanji City should adopt urban spatial structure of the smart growth,continue to use the T-shaped space development strategy, and enhance the independence of the western satellite city of Chaoyangchuan.
