近十年青岛市红岛经济区土地开发利用变迁遥感分析

Remote Sensing Analysis on Land Use Changes in Red Island Economic Zone of Qingdao City Since the Last 10 Years

红岛经济区是青岛市拥湾发展战略中的胶州湾北部新兴城市核心,是近年来和未来一段时间城市经济发展和城区扩张的主要区域。基于2003年和2013年的SPOT-5和资源三号高空间分辨率遥感影像,开展了青岛市红岛经济区近10年来的土地开发利用变迁遥感监测,进行了信息提取和2时相监测结果的土地开发利用转移矩阵分析。盐田和耕地向工业用地的大面积转化。伴随着工业用地的大面积增加,公路用地的面积也在增加,附带的公路防护林的面积也有了显著的增加,研究区域的工业化发展水平显著上升。

Red Island Economic Zone,an emerging urban core in the northern part of Jiaozhou Bay,is the main area of economic development and urban expansion in recent years and in the future.Based on the SPOT 5 and ZY 3 high spatial resolution remote sensing images in 2003 and 2013,remote sensing analysis on land use changes in Red Island Economic Zone since the last 10 years has been carried out.Information extraction and the transfer matrix a-nalysis of development and utilization on land monitoring results of two times have been carried out as well.The areas of salina and plowland have largely transferred into industrial land.Accompanied by a great increase in the area of in-dustrial land,there is also an increase of roads area and highway shelterbelt area.These results indicate a significant raise in the industrialization level of the study area.
