摘　　要：简要介绍应用遥感手段进行区域干旱监测的科学意义和应用价值,按照波段划分,将区域干旱遥感监测模型和方法归纳为热红外、可见光-近红外-热红外和微波三个部分,分析了目前的模型与方法中存在的问题和难点,应用遥感数据源反演地表参数带来误差及地面实验验证模型等需要解决的问题,最后对未来的工作和研究重点提出建议。The scientific meaning and significance of application of remote sensing to monitor the arid area are introduced in this paper. According to the band divisions, we divide all models of arid area monitoring into three parts, according to their spectrum used, i. e. ： thermal infrared, visible-near infrared-thermal infrared and microwave. Analyzing some problems and difficulties in current models, some errors could be caused in the parameters inversion while using various images of remote sensing and some problems could be caused in the verification experiment; at last, some suggestions and emphases for future work are brought forth.
