摘要
文章基于陆地资源卫星(Landsat)的多光谱数据,利用目视判读和矢量数据编辑的方法,分别对宜宾市3个时相(1990,2001,2013年)的遥感影像数据进行操作处理,提取各时相下的宜宾市翠屏区建成区范围,得到建成区土地利用扩张图(1990—2013);基于宜宾市辖区范围内的DEM数据,利用Arc GIS空间分析工具制得宜宾市地形坡度图,再结合相关时期的城市发展规划,分析得出,周边地形、交通状况和城市发展规划对宜宾城市扩张的影响比较大;从宜宾建成区土地利用扩张图可知,各时期的城市建设与对应时期的城市发展规划基本相符。
The digital image process has been done in Y ihin city based on the remote sensing data of 1990,2001 and 2013 to invesligate the expansion of lmih-up land in Cuiping area of Yibin city. The l,andsal ulultispectral data was used as the data source, what＇s more, both the visual interpretation aIHl data analysis niethods wel＇e used in the process. Based on DEM data within the scope of Yibin City area, the slope map eould be made by using ArcGIS spatial anttlyst tools. Combined with the urhan development plan flJr the relevant period, ttie analysis resuhs： the surrounding terrain, traffic conditions and urimn development plan affect the urban expansion of Yibin relatively large. From theland use expansion map of Yibin city＇ s, the urban development planning is basically consistent with tile corresponding period of the urban construction.
