我国超大城市生态安全治理困境及发展路径研究OACHSSCD

With the continuous advancement of urbanization and the intensification of ecological risks,the issue of ecological security in megacities has attracted extensive attention.Advancing ecological security governance facilitates the coordinated realization of high-quality development and high-standard ecological protection.Supported by theories such as ecosystem services,and in line with the Outline of the 15th Five-Year Plan for National Economic and Social Development of the People's Republic of China,this paper analyzes the practical dilemmas and development paths of ecological security governance in Chinese megacities.The study finds that:(1)Although China's megacities have made phased achievements in ecological security governance,they still face problems such as fragmented ecological space,imbalanced resource supply and demand,insufficient risk prevention and control and governance coordination.These problems are closely linked to development mechanisms,governance concepts and technical means;(2)Ecological security governance in megacities is driven by both international and domestic development demands,and is of great significance for maintaining ecological stability,improving governance capacity and ensuring high-quality development.Looking ahead,focus should be placed on the core requirements of high-quality development,and a solid ecological security barrier should be forged through optimizing territorial space,improving resource utilization efficiency,strengthening risk prevention and control,and innovating collaborative governance.
