中国北方草原区积雪遥感监测——2007.10~2008.3期间

Remote sensing monitoring of grassland snow in China: From October 2007 to March 2008

着眼于我国草原防灾减灾以及国家开展重特大雪灾应急响应工作的极迫切现实需求,基于NASA MODIS数据,以天为监测(响应)时间单元,以旬为监测集成时段,对2008年春节大雪灾期间我国草原积雪状况实现了系统的遥感监测,获取了2007年10月至2008年3月期间中国北方9省区草原积雪发生范围及其面积等数据信息,揭示了监测期间我国草原积雪发生的时空特征.青藏高原与内蒙古为我国持续降雪的核心区域,其他地区降雪情况随时间出现一定的波动;除东北地区外,积雪面积均在1月下旬达到最大值;各省区草原积雪面积占草原总面积的比例随时间的变化总体持续增加.水利论文"Z^:y(B)|9k,Y
