摘要
土地利用/土地覆盖变化检测是资源环境研究中的一个重要方面,准确、及时的变化信息为人类资源环境的生产和管理提供了决策支持。遥感技术具有实时、快速、覆盖范围广、多光谱、周期性等特点,给土地利用/土地覆盖变化检测提供了理想的数据基础。人类社会的发展对土地利用/土地覆盖变化检测的精度与效率不断提出新的要求,这也使得一些新技术、新方法引入到变化检测中。这些新技术新方法提高了土地利用/土地覆盖变化检测的精度,但在效率方面有待进一步研究。
Land use / land cover change detection is an important aspect in resource and environment researches. Precise and timely change information will provide the decision-making support for the production and management of human resource and environment. Remote sensing technique has the characteristics of real time, rapidity, wide cover range, multi-spectrum and periodicity, which provide the perfect data foundation for land use / land cover change detection. Consequently, the development of human society has put the new demands on the precision and efficiency of land use / land cover change detection. Thus, some new techniques and methods are introduced into those areas. The new techniques and methods raise the precision of change detection; while their efficiencies still wait for the study.
