摘要:
 利用豫西栾川和西峡2县的102块样地野外调查资料，选取9个分别代表地表可燃物、地形、环境的指标，用线性相关分析法对油松纯林地表细小可燃物负荷量的时空变化规律进行分析。结果表明：油松地表可燃物负荷量与龄级、坡度和郁闭度相关性极其显著；其随着坡度增大而减小，随着龄级、郁闭度增大整体呈现线性增加趋势，但上层可燃物负荷量在第Ⅳ龄级时稍有减少后再增加。30 a左右的油松林地表可燃物负荷量最大。最终建立的上层可燃物负荷量预测模型为：M1=793.533+7.774X1-17.863X3，下层可燃物负荷量预测模型为：M2=1 082.972+13.514X1+902.509X2-34.197X3。
Abstract:
 Based on the data of field investigation on 102 sampling plots,9 indices which represented surface fuel loading,terrain,and environment were selected to investigate the regularities of spatial and temporal variations of the loading capacity of the fine fuels on the surface of Pinus tabulaeformis forest by linear correlation method.Most significant correlations were found between the surface fuel loading and age class,slope,and the canopy density.The loading capacity decreased with the increase of slope degree,and tended to decrease with the increase of age class and canopy density,except that the loadings slightly decreased first and then began to increase at the age class of IV.The maximum loading capacity appeared in 30-year forest.The models of the loadings of the up and bottom layers were established as M1=793.533+7.774X1-17.863X3 and M2=1082.972+13.514X1+902.509X2-34.197X3,respectively.
