| 摘 要： | 研究了松嫩草原羊草可燃物含水率的变化规律，结果表明，在枯死过程中，植物含水率呈下降趋势，１０月末达到此期的最低值，在３０％；在枯草期，植物含水率变化不显著，在１０％波动，雨后羊草可燃物含水率升高，但经过７－８ｈ就恢复到雨前水平。另外，可燃物含水率的变化、雨后可燃物含水率的变化与气象因子之间具有一定的相关关系。

| Abstract: | The changing pattern of Aneurolepidium chinense fuel moisture was studied in Songnen plain. In the process of withering, there was a trend for plant moisture to descend,by the end of October the plant moisture attained the minimum value (30% ) in this period;in litter period, there was an insignificant change in plant moisture (around 10% ). The post-rainfall moisture of Aneurolepidium chinense fuel went up, while restored the pre-rainfall level after 7 ~ 8 hours. In addition, there was a certain correlation among the diurnal change of fuel moisture, the change in post-rainfall fuel moisture, and climatic factors. |
