丘陵城市城乡交错带生态控制线优化策略—以湖南省长沙市湘江新区空间战略规划为例

【摘　要】城市开发边界的划定是保障城市基本生态安全、实现可持续发展的重要工作内容，城乡交错带的生态斑块与城镇组团具有相互交错、破碎、融合的特点，是城乡统筹发展过程中空间管理最为薄弱的区域。文章在分析现有城乡交错带控制线的划定方法、管理等环节存在问题的基础上，提出丘陵城市城乡交错带生态控制线优化策略，并针对湘江新区丘陵城市特征明显的区域，以生态空间统筹过程中的动植物栖息地保护、河流水系小流域治理、城镇开发动力和生态保护平衡等问题为重点，提出了新的城乡之间、人与生态之间的平衡方法。

Ecological Control Line Improvement Strategy Of Hilly Cities: Xiangjiang New District, Changsha City, Hunan Province/Zhao Guangying, Li Chen, Zhou Jianfeng, Wang Ziyu
[Abstract] Urban growth boundary protects the basic ecological safety of a city and helps achieve sustainable development. Ecological patches and towns in urban rural fringe area are interacted, fragmented, and mixed with the least governance.
