| 森林-城镇交界域火灾是当前世界各国面临的重大自然灾害之一。营造各种由难燃植被组成防火林带的生物防火技术是阻隔森林火灾的有效方法,而防火林带树种筛选的研究是生物防火工作的重点内容之一。对东北地区森林-城镇交界域19种常见草本和木本植被的被引燃性能、热释放性能、烟气释放性能、含水率等燃烧特性指标进行了测定与分析。通过结合层次分析法、理想解法和德尔菲法较为全面地对影响植被防火性能的因素集进行综合评价,并得到了各种植被防火性能的定量化对比结果,为开展生物防火应用,正确选择生物防火隔离带提供了科学依据。结果表明,百合、蒲公英、蒙古栎的防火性能较强,可以在东北地区作为交界域防火林带植被加以推广。 |

| The wildland-urban interface fire is a significant natural disaster faced by countries worldwide. One effective forest fire prevention method is using various fire-resistant vegetation to constitute fire-resistant forest belts. Therefore, selecting appropriate tree species for these belts is crucial in biological fire prevention work. This study measures and analyzes combustion characteristics indicators such as ignition performance, heat release performance, smoke release performance, and equal moisture content of 19 common herbaceous and woody vegetation species found in the wildland-urban interface of Northeast China. By integrating the Analytic Hierarchy Process, Ideal Solution approach, and Delphi method, a comprehensive assessment is conducted to evaluate the factors influencing vegetation fire prevention performance. This enables obtaining quantitative comparative results of diverse vegetation fire prevention performances. The findings provide a scientific foundation for implementing biological fire prevention and the appropriate selection of biological firebreaks. The results demonstrate that lilies, dandelions, and Mongolian oak exhibit robust fire prevention capabilities, thereby recommending their promotion as interface fire forest vegetation in the Northeast region. |
