| 摘 要： | 研究草地可燃物含水率与环境因素的关系,以及草地燃烧系统各组分含水率的年变化动态。结果表明草地死体可燃物的含水率变化与天空总幅射、大气温度的变化呈负相关,与大气湿度的变化呈正相关;与地表温度相关不显著。活体可燃物含水率一般不低于30％;草原死体可燃物一年中的每天都有着火的含水率条件(除有降水外),活体可燃物一般不燃,草原燃烧系统夏季难燃,冬季有积雪覆盖不燃,最易燃着的季节是每年的4～6月和10～11月。

| Abstract: | The water content of grassland fuel is an important factor to decide whether the grassland to burn. The paper worked out the relationship of water content of grassland fuel to atmosphere temperature, percent moisture of atmosphere and solar radiation and soil temperature.Hypothetical curves of percent moisture of dead fule, living fuel, total fuel and burning system were given. At the sametime, their dynamics changing role in a year was discussed. |
