| 摘 要： | 基于1996～2005年黑龙江省大兴安岭林区的气象数据及林火数据,比较研究了3种常用的气象火险指数（KBDI、FFDI和NMCI）在大兴安岭林区的适用性。结果表明,FFDI适用于日和月尺度的大兴安岭林区森林火险预报,而NMCI更适于年尺度的大兴安岭林区潜在森林火险评价,但3种气象火险指数与发生林火的相关系数均不高,需要进一步修正其初始条件或选择更合适的参数,以达到更好的预报效果。 |

| Abstract: | Based on the weather data and the forest fire data from 1996 to 2005 in Daxing'anling forest region,Heilongjiang Province,the adaptability of three kinds of forest fire danger weather indices(KBDI,FFDI and NMCI)was analyzed.The results showed that FFDI index was the most suitable one for Daxing'anling forest region on daily and monthly scales,and NMCI index was more suitable on yearly scale.However,the correlation coefficients of all three indices were not high,and it indicated that it is necessary to find more appropriate initial conditions or parameters for the assessment of forest potential fire danger in this region. |
| Keywords: | Forest fire danger Fire danger weather index Daxing'anling |
