运用1992、2002、2009、2014年四期Landsat成都市区遥感影像进行成都市建筑区提取,基于4期Lanndsat影像的成都市主城区提取结果,运用形状特征、空间紧凑度、空间破碎度等相关空间形态特征评价因子,分析成都市主城区1992-2014年间的空间形态动态特征,结合成都市发展状况,统计成都市主城区空间形态特征变化,分析主城区扩张的趋势特征和原因,为成都市未来规划发展和人居环境的改善提供相关依据和支持。 Based on the remote sensing image of Landsat Chengdu in 1992, 2002, 2009 and 2014, the construction area of ​​Chengdu was extracted. Based on the results of the four-stage Lanndsat image analysis of the main urban area in Chengdu, the shape features, spatial compactness and spatial fragmentation were used Spatial characteristics of the evaluation factors of spatial analysis of Chengdu city from 1992 to 2014, the dynamic characteristics of space, combined with the development of Chengdu, the statistical characteristics of Chengdu City, the main urban spatial characteristics of the expansion, analysis of the main urban expansion trend characteristics and causes for Chengdu Future planning and development and improvement of the living environment to provide relevant basis and support.
