遥感技术是研究土地利用/覆被变化状况的重要手段之一,目前该技术已有一套较成熟的研究方法,本文从遥感数据选择、图像预处理方法、土地利用/覆被变化遥感分类、土地利用/覆被变化动态信息提取等方面对土地利用/覆被变化遥感动态监测技术进行了系统的论述,最后指出多信息源、综合的信息处理机制将是土地利用/覆被变化遥感动态监测技术发展的必然方向。
Remote sensing monitoring is one of the important means fot the of land use/vegetation cover changes. This technology has a set of mature methods at present. This paper discusses systematically the dynamic remote sensing monitoring technology for the land use/vegetation cover changes in terms of the data sources selection, image pretreatment, classification and dynamic information acquisition. The paper points out that multi-information sources and comprehensive information processing mechanism will be the future means of dynamic remote sensing monitoring for land use/vegetation cover changes.
