| 摘 要： | 及时、准确地获得湿地的空间分布,对湿地的动态监测、保护与可持续利用具有重要的意义.环境灾害遥感小卫星星座A、B星(HJ-1A/1B星)是我国自主发射的陆地资源监测卫星,可为湿地类型的提取提供新的遥感影像数据源.本文通过对比我国环境灾害遥感小卫星CCD相机影像(HJ CCD)数据与Landsat TM5影像数据获取的湿地景观类型图的分类精度和各景观类型面积,验证和探究了HJ CCD数据在湿地景观动态变化监测中的适用性和应用潜力.结果表明:HJ CCD数据在地物识别分类方面可完全替代Landsat TM5数据;在实时动态监测方面,HJ CCD数据获取周期仅为2 d,优于Landsat TM5数据(16 d).

| Abstract: | To timely and accurately acquire the spatial distribution pattern of wetlands is of significance for the dynamic monitoring,conservation,and sustainable utilization of wetlands.The small remote sensing satellite constellations A/B stars(HJ-1A/1B stars) for environmental hazards were launched by China for monitoring terrestrial resources,which could provide a new data source of remote sensing image acquisition for retrieving wetland types.Taking Liaohe Delta as a case,this paper compared the accuracy of wetl... |
