| 中文摘要: |
| 为探明黑龙江省宾西地区森林—城镇交界域不同森林类型发生火灾的风险和强度,以黑龙江
省宾西地区森林—城镇交界域阔叶混交林、针阔混交林和落叶松林的枯落物、腐殖质、灌木为研究对象,通过测量含水率、燃点、热值和灰分含量,综合评估交界域不同林型可燃物的燃烧特性。结果
表明,落叶松林的灌木层燃点显著低于其它两种林型,热值高于其它两种林型。落叶松林的可燃性得分最高,为1.816 966,其次为阔叶混交林1.614 785,针阔混交林可燃性最低,为1.564 699。宾西地区森林—城镇交界域落叶松林防火性能最弱,针阔混交林防火性能最好,可以在林下种植高灰分耐火植物以提高交界域的防火性能。 |

| To clarify the risk and intensity of fires in different forest types in the forest-urban boundary
area of Binxi region, Heilongjiang Province, this study investigated the litter, humus, and shrubs in broadleaf
mixed forests, coniferous-broadleaf mixed forests, and larch forests. By measuring moisture content,
ignition point, calorific value, and ash content, the combustion characteristics of fuels in different forest
types within the border area were comprehensively evaluated. The results showed that the shrub layer in
larch forests had a significantly lower ignition point and higher calorific value compared to the other two
forest types. The flammability score was highest for larch forests(1.816 966), followed by broadleaf
mixed forests(1.614 785), and lowest for coniferous-broadleaf mixed forests(1.564 699). The fire resistance
of larch forests in the forest-urban boundary area of Binxi region was the weakest, while that of
coniferous-broadleaf mixed forests was the strongest. Planting high-ash, fire-resistant plants under the
forest canopy can improve the fire resistance of the boundary. |
