| 摘 要： | 土地利用/覆被变化（LUCC）是全球变化的主要原因和核心主题之一。本文通过综述国内外LUCC研究成果，阐述了国际上LUCC研究在信息获取、数据处理、驱动力分析和模型建立等方面所取得的最新进展，分析了LUCC研究对干旱区生态环境保护与区域可持续发展实现的研究意义，介绍了LUCC研究的新趋势，并对研究过程中现存的一些如信息获取过度依赖于3S技术，忽视实地调研等传统信息获取方式与新技术手段的结合、模型功能的欠完善、干旱区土地实现可持续利用缺乏相应的比较全面的科学理论指导等问题进行了讨论。研究认为，健全LUCC研究理论体系，开展相应的理论建设将是未来整个LUCC研究工作的一个重要方向和趋势。

| Abstract: | Land use and land cover change was one of the main reasons and core subjects of the global environmental change. Based on the domestic and foreign LUCC research results, we elaborated the latest LUCC research progress in information acquisition, data processing, driving force analysis and model development. The significance of the LUCC study to environmental protection and regional sustainable development in arid regions was analyzed. Then, we introduced the new tendency of LUCC research and pointed out some problems in such process, for instance, excessively relying on 3S technology in the process of information acquisition, the neglecting union between tradition information acquisition ways and the new technological means. Moreover, the imperfect function of LUCC model, the deficiency in comprehensive and scientific theory to instruct arid area land to realize the sustainable etc., also were indicated in this research. We think that theory exploration will be the key to the research of LUCC in the future because of its guidance to the direction of LUCC study. |
