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。

关 键 词:国有林区  生态环境脆弱性  黑龙江省

Ecology Environment Vulnerability Change Trend of State-owned Forest Area in Heilongjiang Province
Abstract:After positioning the ecology environment vulnerability connotation of state-owned forest area , we set up ecology envi-ronment 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 invest-ment, forestry laws soundness , wastewater discharge compliance rate , rainfall, accumulated temperature , total water re-sources, 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 .
Keywords:State-owned forest area  Ecology environment vulnerability  Heilongjiang Province
