摘要
利用1987-2007年福建省森林灾害统计资料,对森林病害、森林虫害和森林火灾等3种福建省主要森林灾害的统计特征进行分析,并运用改进的灰色关联分析方法分析这3种森林灾害对林业生产的影响.统计资料显示,福建省主要森林灾害灾情严重,森林虫害的发生面积最为突出,森林火灾的防治率最低.灰色关联分析表明,影响福建省林业生产的主要灾害是森林病害,其次是森林火灾,最小的是森林虫害.4阶段动态分析结果显示,森林火灾对林业生产影响有明显上升趋势,森林病害有下降趋势,森林虫害呈波动性且有下降的趋势.
Based on the statistical data of forest disasters from 1987 to 2007 in Fujian Province, this paper analyzes the statistical characteristics of the main forest disasters including diseases, insect pests and fire, aad their impact on forestry production by using improved grey correlation analysis. Statistics showed that the main forest disasters were very serious in Fujian, and the area of forest diseases occurrence was prominent and the fire preventing and controlling rate was lowest. The results of grey correlation analysis showed that the main forest disaster was forest diseases, followed by forest fire, and the least was forest pests. Dynamic analysis of 4 stages showed that the impact of forest fire on forestry production had a growing trend, and that of forest dis＇eases had a declining trend, while that of forest pests had a declining trend with fluctuation.
