摘 要:在定位生态环境脆弱性内涵基础上,设置了国有林区生态环境脆弱性的评价指标体系,利用主成分分析方法对生态环境脆弱性指标进行赋权,利用灰色关联分析法监测黑龙江省国有林区2004—2014年的生态环境脆弱性变化趋势。结果表明:黑龙江省国有林区生态环境脆弱性的驱动因子,排在前10位的依次为森林火灾受害率、森林病虫鼠害受害率、营林投资力度、林业法律法规健全度、废水排放达标率、降水量、积温、水资源总量、过熟林比例、无林地比例;黑龙江省国有林区生态环境脆弱性,表现出逐年降低的趋势。After positioning the ecology environment vulnerability connotation of state-owned forest area,we set up ecology environment vulnerability evaluation index system of state-owned forest area. We used factor analysis to calculate indictor weight and gray relational analysis to monitor ecology environment vulnerability change trend of state-owned forest area in Heilongjiang Province from 2004 to 2014. The top ten ecology environment vulnerability driving factors of state-owned forest area in Heilongjiang Province were forest fires victimization rate,forest pest and rodent victimization rate,forestry investment,forestry laws soundness,wastewater discharge compliance rate,rainfall,accumulated temperature,total water resources,over mature forest rate,and non-forest land rate. The ecological environment vulnerability of state-owned forest in Heilongjiang Province showed constantly decreasing trend year by year.
