摘要
土地生态安全作为生态文明建设的核心内容,是保证区域可持续发展的重要前提。为了探索出雄安新区土地生态安全的有效路径,采用系统仿真的方法,对不同发展路径下雄安新区土地生态安全状况进行了研究,研究结果表明:①构建的雄安新区土地生态安全系统仿真模型模拟效果良好,具有很强的可操作性,能够对雄安新区未来的发展状况进行模拟。②协调发展路径下,土地-经济、土地-社会、土地-自然混合子系统均能表现出更强的动力,在2030年雄安新区的土地生态安全状况最优。
Land ecological security,as the core content of ecological civilization construction,is an important prerequisite to ensure the sustainable development of the region.In order to explore the effective path of land ecological security in Xiong’an New Area,the ecological security of land in Xiong’an New Area under different development paths is studied by means of system simulation.The results show that:①The simulation model of the land ecological security system in Xiong’an New Area has good effect and has strong maneuverability.②The land-economy,land-society,land-natural hybrid sub-system can show stronger power under the coordinated development path,and the land ecological security condition of Xiong’an New Area is optimal in 2030.
