| 摘 要： | 利用专用遥感数字图像处理软件ERDAS及地理信息系统软件ARCGIS软件,以唐山市1990年,1999年的卫星遥感图像为数据源,研究唐山市矿区的建设用地变化.对遥感图像进行分类,并根据分类结果提取建设用地的二值图像,对二值图像进行变化检测,得到建设用地的增减分布图,同时结合矿区分布图,通过图像叠加复合分析,在研究区内分出二个子研究区,分析城市扩展情况和扩展方向,以及农村建设用地情况.研究结果表明:唐山市城市区域的建设用地增加较多,以外向型扩展为主,具有明显的方向性;处于矿区及矿区附近的农村建设用地有明显的减少.

| Abstract: | Making use of special remote sense digital image software ERDAS and the geographic information system software ARCGIS ,with the artificial satellite remote sense image of Tang Shan City in 1990,1999 ,the change of Tang Shan City mining area construction land is studied. Drawing the bilevel image of construction land according to classification detecting the change on bilevel image,construction land distributing picture on adding or subtracting are obtained. According to the two small studying areas allotted out,city expanding condition and expanding direction,rural construction land condition are analyzed. The studying result indicates Tang Shan city area's land increase by more with obvious directionality; In mining area and neighboring rural construction land obviously decrease. |
