摘　　要：通过研究松嫩草原羊草可燃物含水率的变化,揭示羊草可燃物燃烧性的变化规律.结果表明,在羊草枯死过程中,其燃烧性呈上升趋势,10月末达到最高值;在枯草期,其燃烧性变化不显著.雨后羊草可燃物燃烧性降低,经过7～8h恢复到雨前水平.另外,可燃物燃烧性的变化规律与气象因子密切相关.The changing pattern of Aneurolepidium chinense fuel moisture was studied in order to discover the changing pattern of Aneurolepidium chinense fuel flammability in Songnen Plain. In the process of withering, there is a trend for plant flammability to ascend, by the end of October the plant flammability reaches the maximum value in this period, in the latter period, there is an insignificant change in plant flammability. The postrainfall flammability of Aneurolepidium chinense fuel goes down, but restores the prerainfall level after 7～8 h. In addition, the flammability is related with climatic factors.
