多光谱遥感数据城市边缘区土地利用时空结构演化
|
摘要
针对城市边缘区空间扩散变化规律问题,以北京市北郊地区为研究区,提出了利用多源多光谱遥感数据提取城市土地利用信息,分析土地利用时空结构,进而研究城市扩散规律。采用2004年SPOT-5、2009年ALOS、2014年SPOT-6三期遥感数据,以ArcGIS作为空间数据分析处理工具,利用梯度分析法、等扇形分析法、城市空间形态演化分析重现城市边缘区时空结构的变化过程,对各时期的北京市北郊时空结构进行了分析,得出2004—2014十年间北京市北郊时空结构演化结果。研究表明,十年间北京市北郊地区扩张分布均匀,在2004—2014十年间土地利用结构变化显著,且主要原因是由于建设用地的增加和扩张。该研究为城市边缘区的城市规划、建设、环境保护提供了依据。
Aiming at the law of spatial diffusion change in urban fringe areas,taking the northern suburbs of Beijing as the research area,we propose to use multi-source multi-spectral remote sensing data to extract urban land use information,analyze the spatial and temporal structure of land use,and then study the law of urban diffusion.This article is based on 2004 SPOT-5,2009 ALOS,2014 SPOT-6 three remote sensing data,using GIS as a spatial data analysis and processing tool.It uses the gradient analysis method,the fan-shaped analysis method,and the urban spatial form evolution analysis to reproduce the process of the temporal and spatial structure of the urban fringe.This paper analyzes the temporal and spatial structure of the northern suburbs of Beijing,and gets the results of the evolution of time and space structure in the northern suburbs of Beijing in 2004-2014.The study shows that the expansion of the northern suburbs of Beijing is evenly distributed within ten years,the land use structure has changed significantly during the 2004-2014 decade,and the main reason is due to the increase and expansion of construction land.This study provides the basis for urban planning,construction and environmental protection in urban fringe areas.
