Modeling on Prescribed Burning Width of Fire Isolated Belt of Pinus kesiya Forest
摘要
Abstract
Based on field survey and measurement, and the simulated field burning test by indoor burning bed, a multivariate linear model was established with 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. 916 x6 +0. 540x7, influencing factors of prescribed burning width of fire isolated belt were arranged in order of x6, x7, x1, x4, x3, x2 and x5. The model selected factors of characteristics of combustible materials, terrain, meteorology, stand which could be acquired easily to open fire isolated belt width, which provided support for prescribed burning and forest management burning, etc.关键词
