不同含水率雪松木的裂纹演化规律试验研究

为了研究不同含水率工况下木材试件的裂纹发展,探寻含水率对木材的力学性能影响和裂纹演化规律。以0、10%、20%、30%、40%及50%含水率的雪松木试件为研究对象,利用力学试验机和声发射设备收集在荷载下木材发出的声发射能量信号。结果表明,不同含水率下木试件的裂纹演化规律与声发射检测得出的结果一致。含水率越高,试件的裂纹发展越平缓,承载能力也越低,说明振铃计数和能量可以准确反映出木材的损伤,木材的裂纹演化程度与含水率成反比。试验结果为进一步研究含水率与木材的影响关系提供了参考。

Impact of Droughts on Cedrus atlantica Forests Dieback in the Auras （Algeria）

Cedar forests area in northeastern Algeria （Aures） is decreasing by the massive tree mortality. In some localities more than 95% of the trees have recently died （e.g. Boumerzoug in Belezma National Park）. Three reported episodes of massive tree mortality in 1880, 1980, and 2000 were attributed to drought at least as the triggering factor. Our main objective was to reconstruct drought events that could be linked to Atlas cedar tree mortality using tree-ring series. We developed a Cedrus atlantica tree-ring width chronology in Chelia with a reliable period spanning from 1502 to 2008. Based on the relationship between chronology indices and instrumental precipitation data, we reconstructed total October-June precipitation. Dry events were identified using a threshold of 90% of the October-June mean instrumental precipitation. The unique drought event of 3-year period （1877-1879） could explain the tree mortality occurred in 1880. In terms of severity and frequency of droughts, the later half of the twentieth century seems to be the worst and may be responsible for the recent tree mortality.
