中文摘要：

积雪的重要性是不言而喻的同时积雪所带来的危害也受到越来越多的重视。目前，积雪深度遥感监测研究主要集中在微波遥感，少量的利用光学遥感进行的积雪深度研究也主要是利用气象卫星数据以及MODIS数据等。我国自主发射的环境与灾害监测小卫星无论是在光谱分辨率还是在空间分辨率上，都与气象卫星数据以及MODIS数据有较大区别，对利用HJ-1B卫星数据进行积雪深度反演的研究较少。该文主要利用HJ-1B卫星数据，研究常规降雪深度状况下的积雪深度遥感监测方法。利用野外不同下垫面及深度状况的积雪光谱，在积雪覆盖信息提取的基础上，通过分析积雪覆盖指数以及HJ-1B卫星不同波段（绿光波段、近红外波段、短波红外波段）反射率与积雪深度的相关关系，建立了适用于HJ-1B星的积雪深度反演模型。模型验证结果表明，该模型能够满足较浅降雪深度状况下的遥感实时监测要求。

英文摘要：

The importance of the snow is self-evident, while the harms caused by the snow have also received more and more attention. At present, the retrieval of snow depth mainly focused on the use of microwave remote sensing data or a small amount of optical remote sensing data, such as the meteorological data or the MODIS data. The small satellites for environment and disaster monitoring of China are quite different form the meteorological data and MODIS data, both in the spectral resolution or spatial resolution. In this paper, aimed at the HJ-1B data, snow spectral of different underlying surfaces and depths were surveyed. The correlation between snow cover index and snow depth was also analyzed to establish the model for the snow depth retrieval using the HJ-1B data. The validation results showed that it can meet the requirements of real-time monitoring the snow depth on the condition of conventional snow depth.
