The Traditional Industrial Area of northeastern China is an important traditional industrial and grain production base of China, and its ecological security is related to the implementation of sustainable development strategies. Based on the emergy-ecological footprint model, the ecological security in Traditional Industrial Area of northeastern China was quantitatively evaluated from 2000 to 2014, followed by a scenario analysis on the driving forces of the ecological security using a principal component analysis method. The results showed that, the value of emergy ecological-capacity per capita decreased from 0.66 to 0.64 hm2/cap, whereas the emergy-ecological footprint increased from 10.58 to 19.85 hm2/cap, which indicated that an ecological deficit existed in the Traditional Industrial Area of northeastern China. The ecological pressure in this area increased, showing an unsustainable development trend from 2000 to 2014. The ecological pressure index and ecological security levels gradually increasing, ecological security situation is deteriorating, ecological security issues to be urgent resolved. The ecological stress tended to be serious as a result of a combination of several factors, such as social, economic, population, resource, environmental, technological level, and land use degree. Finally, effective management strategies and suggestions to improve the ecological security of the Traditional Industrial Area of northeastern China were proposed. 参考文献 相似文献 引证文献
