基于突变级数法的福建省森林火灾评价分析

突变级数法吸收了层次分析法和模糊评价法的优点,在具有突发性的森林火灾多目标评价体系中具有优越性.本研究利用1998 - 2007年福建省森林火灾统计资料,结合当前森林火灾评价的研究成果,构建了福建省森林火灾损失评价指标体系,并利用突变级数法对其进行评价分析.结果表明,福建省近10 a森林火灾总体损失严重,重灾年份所占比...

Evaluation and analysis of forest fires in Fujian Province based on catastrophe progression method

Catastrophe progression method has absorbed the advantages of analytic hierarchy process(AHP) and fuzzy evaluation,which has the advantages in the study of the multi-objective evaluation system of sudden forest fires.In this study,based on the statistics data of forest fires in Fujian Province from 1998 to 2007,in the light of advances in the evaluation of forest fires,an indices system to evaluate the loss from forest fires in Fujian Province was set up.Then it was evaluated and analyzed thought catastrophe progression method.The results showed that in recent 10 years,the overall loss of forest fires was serious and with a significant share of disastrous years in Fujian Province.Secondly,the loss of forest fires fluctuated severely,which had a great gap between the most serious disasters in 2004 and the lightest in 1998.It has been proved that catastrophe progression method with satisfactory results should be adopted in the multi-objective evaluation system of forest fires.
