摘要
通过对大兴安岭林区呼中、新林两个林业局观测站的可燃物含水量进行了分析,结果表明:两个站观测到的可燃物含水率全年变化幅度较大,在细节上表现不尽相同,但其变化趋势基本一致,变化曲线表现为明显的双峰型,多在5月中旬达到最小值。利用可燃物含水率与相关显著的气象因子建立线性回归方程,模型的复相关系数为0.696,通过了0.01的显著性检验,可用于可燃物含水率预报。
In this paper,the forest dead fuel moisture in Huzhong and Xinlin of Da Xing'an Mountains has been analyzed.The results showed that the yearly change of fuel moisture is sharper,the display in the detail is different,but its change tendency basic consistent.The change curve is obvious twin peaks,many achieves the minimum in mid-May.Made use of the regression method to establish the equation on the forest fuel moisture,the model duplicate correlation coefficient is 0.696,adopted 0.01 significance examination,it could be applied to predict the fuel moisture.
