城市生态安全研究进展

Review of urban ecological security research

当前城市化发展使得人口大量涌入城市,各种城市生态安全问题显现。城市生态安全是城市居民生产、生活的重要保障,对推动绿色发展、促进人与自然和谐共生具有重要意义。梳理了城市生态安全的相关概念,从城市生态安全评价、影响因素分析、城市生态安全预测与预警以及基于生态安全的城市格局构建与空间规划4个方面介绍了目前城市生态安全研究的主要成果与不足。在此基础上,指出了未来需要重点开展的研究,包括:1)探索建立城市生态安全评价标准体系,以实现城市生态安全的规范化评价,并服务于管理实践;2)加强从更大尺度上开展城市生态安全研究,如从城市群或城乡统筹的角度进行研究;3)加强以人为本的城市生态服务安全研究,重视生态系统服务在生态安全领域的应用。

The development of urbanization has caused a massive influx of people into cities,leading to the emergence of various urban ecological security(UES)problems.UES is an important insurance for the production and living of city dwellers,and is of great significance to promote green development and the harmonious coexistence between human and nature.The related concepts of UES was analyzed,and the main findings and deficiencies of the current research on it were introduced from four aspects,i.e.the UES assessment,the analysis of influence factors,the prediction and early warning of UES and the construction of urban pattern and spatial planning based on ecological security.On this basis,the key researches that need to be carried out in the future were pointed out:1)Explore the establishment of an UES evaluation standard system to achieve standardized evaluation of urban ecological safety and serve management practices;2)Strengthen research on UES on a larger scale,such as from the perspective of urban agglomeration or urban-rural coordination;3)Strengthen people-oriented urban ecological service security research,and attach importance to the application of ecosystem services in the field of ecological security.
