技术生态风险视角下城市生态安全PSR模型评价研究——以江苏省镇江市为例

Urban Ecological Security Evaluation of the PSR Model from the Perspective of Technology Ecological Risk——As an Example of Zhenjiang City of Jiangsu Province

技术进步是一把双刃剑,既促进了经济发展,又可能引发技术生态风险。基于PSR模型,镇江市生态安全评价的研究发现,随着技术进步和城市化的进展,生态环境也在恶化。镇江市的生态性态及变化在全国具有一定的代表性,这种分析思想、方法与对策完全可以用于其它各个城市生态评价的分析。技术进步并不一定能够促进健康的城市化进程,如果不注重生态保护,可能会导致城市化进程的崩溃。

Technology is a double-edged sword,which can promote the economic development,and can also lead to technology ecological risk.Based on PSR model,the study of ecological security evaluation of Zhenjiang city shows that ecological environment is deteriorating with the progress of technology and urbanization.Ecosystem and its change of the Zhenjiang have certain representativeness in the nation,and all these thoughts,methods and countermeasures can be used for the ecological evaluation analysis in other cities.Technological progress can promote the healthy urbanization.If we don’t pay attention to ecological protection,it may lead to the collapse of the urbanization process.
