| 摘 要： | 依据实地调查和测量,结合室内燃烧床模拟野外计划烧除试验,考虑可燃物载量(x1)、温度(x2)、可燃物含水率(x3)、风速(x4)、坡向(x5)、坡度(x6)、林带高度(x7)、蔓延速度(x8)、火线强度(x9)及计划烧除防火隔离带宽度(y)等因子构建多元线性回归模型。结果表明,预测的多元线性回归模型为 y=-12.371+4.182x1+0.435x2+0.013x3+0.083x4+0.017x5+0.916x6+0.540x7,对计划烧除防火隔离带宽度的影响大小依次为 x6、x7、x1、x4、x3、x2、x5,利用该模型,可以用易于获取的可燃物特征、地形因子、气象因子、林分因子来开设防火隔离带,为合理开展计划烧除和营林用火等提供依据。

| Abstract: | Based on field survey and measurement,and the simulated field burning test by indoor burning bed,a multiple linear regression model was established with factors of fuel load(x1),temperature(x2),fuel moisture content(x3),wind velocity(x4),aspect(x5),slope(x6),forest height(x7),propagation velocity(x8),fire line intensity(x9) and prescribed burning width of fire isolated belt(y).The results showed that the multivariate linear model was y=-12.371+4.182x1+0.435x2+0.013x3+0.083x4+0.017x5+0.916x6+0.540x7,and the influences of the factors on the prescribed burning width of fire isolated belt were in the order of x6,x7,x1,x4,x3,x2,x5.This model make it easier to establish fire isolated belt by using fuel characteristics,topographic factors,meteorological factors,and forest stand factors,providing basis for the development of prescribed burning and forest management fire. |
