对土地荒漠化遥感监测的研究进行了综述和展望,并指出通过加强多种类荒漠化土地分类指标体系的构建、提高监测精度、不断探讨新的方法及方法的适用性、明确荒漠化遥感监测的宏观技术路线与流程、深入开展成因与影响因子分析以及充分利用多源与多种数据信息等几个方面可以不断对土地荒漠化遥感监测技术进行完善.一方面可为相关决策部门提供有力的科学依据,进而提高荒漠化治理、区域生态环境恢复与重建的水平和效果;另一方面,可为荒漠化发生发展过程、荒漠化机理研究,沙质荒漠化对相关区域乃至未来全球气候变化的影响研究提供依据,进而为当前全球变化研究做出贡献.%The research of remote sensing monitoring of land desertification were summarized and prospected.And pointed out that by strengthening variety of desertification land classification index system construction,improve the monitoring accuracy,and constantly explore new ways and methods of applicability,clear macro technical route and process of remote sensing monitoring of desertification,in-depth analysis to carry out the causes and influence factors,and make full use of multi-source and several aspects,such as a variety of data information can be continuously to improve the land desertification remote sensing monitoring technology.On the one hand can provide scientific basis for the decision-making departments,improve the governance and desertification area ecological environment restoration and reconstruction of the decision-making level and governance effect;On the other hand,can be the researches on the mechanism of the desertification process,sandy desertification influence on regional and global climate change research,and thus contribute to the global change research.
