摘要
基于1994年的Landsat TM(专题制图仪)、2002年和2007年的Landsat ETM+(增强型专题制图仪)3个时相的卫星影像,探讨福建省泉州市洛阳江1994-2007年水域的变化规律.水域变化信息主要通过变化检测和信息提取等一系列遥感技术获得.结果表明:1994-2007年,洛阳江的水域总面积增加了165.60 hm2,双阳镇和洛阳镇以北地区水域面积减少,与泉州市洛江区城市用地的扩展以及福厦高速公路和泉肖铁路的建成通车有关;南部洛阳江主河道变宽,水域面积增加,与沿岸红树林遭受破坏,岸带失去天然保护屏障有关.
This paper discusses water changes of the Luoyang River based on Landsat TM(thematic mapper) satellite image of 1994,Landsat ETM+(enhanced thematic mapper) satellite images of 2002 and 2007.Information of water changes acquired mainly from change detection and information extraction and a series of remote sensing technology.The results show that in the study of 13 years,the overall increase in water area is 165.60 hm2.Owing to the urban expansion of Luojiang District as well as the Fuzhou-Xiamen expressway and Quanxiao railways opened to traffic,the water areas of the north of shuangyang town and luoyang town shrunk during 1994-2007.Also,because of the destruction of coastal mangrove forests and loss of natural barriers,waters of the south area increased and main channel of Luoyang River widened.
