基于PSR概念模型的我国木材安全评价
Evaluation of timber security in China based on PSR conceptual model
摘要
Abstract
To understand and master the situation of timber security,the timber security of China during 1997-2015 was evaluated and analyzed by using PSR conceptual model and Entropy method in this study.The results showed that:1) The pressure of timber security in China during 1997-2015 was increasing in wave with international timber trade as the main factor;2) The state of timber security in China presented an downward-then-upward tendency during 1997-2015.The main influencing factors were domestic timber supply and forest resources condition;3) The responses to ensure timber security of China indicated a steep rising trend due to the improvement of the security of timber in China by both the timber industry technical progress index and the waste paper recovery rate;4) The changing trend of the comprehensive evaluation of timber security in China approximately agreed with that of state evaluation indicating that state indicators were key factors affecting timber security in China.In conclusion,the pressures influencing the timber security of China are on rising.However,the state of timber security and the responses on high-tech industry are improved at a higher range than that of the pressures,which would lead to the increase of China's timber security.关键词
