黑龙江省林地资源安全评价

Evaluation on Security of Forest Land Resources in Heilongjiang Province

参考相关的研究成果,从数量、质量和生态3个层面构建了林地资源安全的评价指标体系,应用因子分析法确定各指标权重并进行综合测试。结果表明,黑龙江省2001年、2004年、2006年、2010年的林地资源都处于基本安全状态,表明林地资源的服务功能良好,生态系统较稳定,林地资源经济、社会安全问题都较少。进一步的分析发现数量安全和质量安全是影响黑龙江省林地资源整体安全的决定性因素,生态安全虽然影响力较小但其不断恶化的状态会对林地资源的数量安全和质量安全产生负面影响,因此需要采取一些措施来保障并提高黑龙江省林地资源的生态安全,进而持续提高黑龙江省林地资源整体的安全状态。

According to related research findings ,this paper chooses indicators of quantity ,quality and ecology to establish an evaluation index system for forest land security .By using factor analysis ,it calculated indicators weight and made comprehensive evaluation .The findings show ：（1）the forest land resources basically remained secure in 2001 ,2004 ,2006 and 2010 in Heilongjiang province ,which indicates good service function of forest land resources at work ,relatively stable ecological system ,and relatively less economic and social security problems;（2）quantity and quality indicators are the decisive factors affecting the security of forest land resources .Though the ecological security has a little impact on the security of forest land resources ,its continuous deterioration will have negative effects in terms of quantity and quality on the security of forest land resources ,at last .So some effective measures should be taken to guarantee and improve the ecological security for sustainable improvement of the forest land security in Heilongjiang Province .
