摘 要：
采用遥感监测和地面样地调查数据相结合的方法,利用枯草期可燃物遥感反演模型,对乌珠穆沁草原防火期,即当年秋季到翌年春季的7个月草地可燃物量的动态变化进行了监测。结果表明,2010年10月至2011年4月,整个枯草期研究区内的可燃物量在空间上表现为由东向西减少趋势。在时间上,可燃物保存率的变化可分为两个阶段:第一阶段是2010年10月到12月,这一阶段可燃物保存率降低较快,月平均递减率为25.9%;第二阶段为2011年1月到4月,这一阶段的降低幅度较小,月平均递减率为7.3%。

摘 要：
Using remote sense monitoring and filed experiments,the dynamic changes of combustible matter were monitored from fall to next spring in Wuzhumuqin grassland.The results showed that the amount of the combustible matter in hay season was declined gradually.And it decreased from east to west in space.At time scale,it can be divided into two phases: the first one was that the preservation percentage of combustible matter declines relatively fast from October 2010 to December 2010,and monthly decreasing rate was 25.9%;the second one was from January 2011 to April 2011,and monthly decreasing rate was 7.3%.
