摘要/Abstract

摘要： 根据区域生态风险评价的理论和方法体系,对东北地区森林资源进行了生态风险评价.东北林区生态风险问题形成的主要胁迫包括物理胁迫、化学胁迫、生物胁迫和社会胁迫,其权重系数分别为0.30、0.22、0.11和0.37.东北93个林业局中,轻风险占64.4%,中风险占21.2%,重风险占13.3%,严重风险占1.1%,符合偏正态分布.东北区森林生态风险的地域分异明显,靠近长白山区的森林处于轻风险和中风险等级,向西生态风险越来越重,处于重风险和严重风险等级的林业局主要集中在小兴安岭地区.必须加强东北区风险管理和森林景观的修复与重建.

Abstract: Based on the theory and methods of regional eco-risk assessment (REA),the eco risk of forest resources in northeast China is evaluated. The stresses resulting in the eco risk of forest resources are physical,chemical,biological and social stresses. The weighed coefficient is 0.30,0.22,0.11 and 0.37,respectively. In93 forest bureaus of this area,64.4% bureaus are in slight risk,21.2% in mid-risk,13.3% in high risk and 1.1% in very high risk. This is in corresponding with the skew normal distribution. The eco risk of forest resourcs in northeast China is closely related to the locality of the resources. The risk becomes more and more serious from east to west. The risk management and restoration of the forest resource must be strengthened.
