内蒙古、新疆、西藏、青海、甘肃和四川的草原区这6大牧区是中国重要的畜牧业生产基地,也是雪灾频发的区域,及时、准确地获取6大牧区雪情时空特征对于防灾减灾,指导畜牧业生产有着重要的现实意义。光学遥感与微波遥感各具优缺点,综合运用MODIS和AMSR-E数据构建草原积雪遥感监测模型,以日为监测单元,以旬为多日合成时段,对中国6大牧区在2008年10月上旬至2009年3月下旬间的草原积雪覆盖范围进行监测,并对监测结果进行检验,以此说明MODIS与AMSR-E数据在雪灾监测方面协同监测的可行性,为其他雪盖遥感监测研究提供参考。
Inner Mongolia, Xinjiang, Tibet, Qinghai, Gansu and Sichuan grassland areas six major pastoral areas is China’s major livestock production base, is also a frequent snow disaster areas, timely and accurate access to six major pastoral snow time and space characteristics of disaster prevention and mitigation It has important practical significance to guide the livestock husbandry production. The optical remote sensing and microwave remote sensing have their own advantages and disadvantages. The MODIS and AMSR-E data are used to construct the monitoring model of grassland snow cover. Taking the Japanese as the monitoring unit and the multi-day synthesis period as ten days, The snow cover of grassland during the first ten days of 2009 to the end of March 2009 was monitored and the monitoring results were tested to demonstrate the feasibility of MODIS and AMSR-E data for collaborative monitoring of snow disaster monitoring. Other snow cover remote sensing monitoring studies for reference.
