摘  要:
采用预处理法,对棋盘山2个常见树种油松、蒙古栎林下细小可燃物的失水过程进行了研究。通过回归分析,建立了相关的模型。结果表明:在75%湿度、不同温度梯度(15、20、25、30、35℃)下,各细小可燃物的平衡含水率和时滞都不同程度受到温度的影响。表现为:平衡含水率与时滞随温度的升高而降低,温度与枯枝和树皮的平衡含水率、时滞分别为二次函数和三次函数关系;与油松落针的平衡含水率和时滞分别为三次函数和四次函数关系。

摘  要:
Relationships between temperature and equilibrium moisture content(EMC)as well as time-lag were probed by investigating the desorption process of fine fuels of Pinus tabulae formis and Quercus mongolica forests with the preprocessing method.A model was established under the support of SPSS with the temperatures ranging from 15 to 35℃(5℃gradient)at the humidity of 75%.The results indicated that both the EMC and time-lag of fine fuels were influenced by temperature to some extent.EMC and time-lag fell as the temperature rised.Relationships of quadratic and cubic functions were found between temperature and EMC,temperature and time-lag of sticks and barks respectively.Cubic function and quartic functions were found between temperature and EMC,temperature and fallen needles of P.tabulae formis.
