Ecological risk assessment of forest resource in northeast China

Abstract

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.

Key words: Northeastern region, Forest resources, Ecological risk assessment
