摘 要:通过对森林公园林内样点喷淋前后木材样块含水率进行连续测定,建立木材样块含水率与测点次数的曲线模型,分析木材样块含水率差异性及变化趋势,从而了解水喷淋对林内木质可燃物含水率的影响程度。结果表明:喷淋后,木材样块含水率从13.3%升至18.8%,之后逐渐下降,维持4 d后恢复到喷淋前状态;含水率维持在17%水平以上的时间为22.06 h,木材样块处在可燃状态,而对照样地木材样块处在易燃状态。Based on the continuous measurement of moisture content of wood specimens when water spray in the sampling points of forest park, the curve model was established between moisture content and the test number, which can be used to analyze the moisture content of wood specimens difference and the variation tendency. It will be helpful for further understanding of how the water spray affects moisture content of combustible material for forest wood. The results showed that: the spray made the moisture content of wood specimens increased from 13. 3% to 18. 8% and then declined, it was maintaining 4 days and then back to the state before spray. When moisture content maintained at more than 17% by the duration of 22. 06 h, the wood specimens were on the flam- mable status, on the contrary, the wood specimens in the eontrastive plots were on the easily flarmnable status.
