| Abstract: | An evaluation system for fireproof effect of biological fire belt by transformed cultivation was constructed using analytic hierarchy process and Delphi survey method,and the weight of each variable and its evaluated value were obtained.The evaluation system includes three levels,five indexes and sixteen variables.Result shows that fire belt width,fire road width,fuel moisture,wind speed,crown width,tree height and canopy density have obvious effects on fireproof functions of fire belt,and the weight values of these variables are 0.293 6,0.146 8,0.096 8,0.089 2,0.055 3,0.044 1,0.043 3,0.030 6,0.029 3,respectively. |
