摘要: 改革开放以来，珠三角地区在活跃的村镇工业化推动下实现了经济与产业的快速发展，但也带来趋向破碎化的城市生态空间。引入租差理论，以利益驱动为分析基础，从政府管控、经济发展、自然环境3方面，构建“政府力—市场力—自然力”的城市生态空间演变动力分析模型，以广东省佛山市南海区为例进行分析。得出结论：（1）2010—2020年间佛山市南海区生态空间演变中，政府力是城市生态空间演变的主要动力；（2）生态用地租金普遍较低，市场力对城市生态空间的影响尚不充分，仅通过土地租金推动生态空间实施难度较大。最后提出规划对策建议：一是建立兼顾生态效益与经济成本的生态空间网络；二是建立以降低其他用途与生态用途的租差为导向的保护与修复配套政策，引导低效建设用地通过生态修复、拆旧复绿向生态空间转化。
Abstract: Since the reform and opening up, the Pearl River Delta has achieved rapid economic and industrial development driven by the active industrialization of villages and towns, but it has also brought a trend towards fragmentation of urban ecological space. This paper introduces the rent gap theory, and based on the analysis of interest driven factors, constructs an urban ecological spatial evolution dynamic analysis model from three aspects: government control, economic development, and natural environment. An empirical analysis is conducted using the Nanhai District of Foshan as an example. The conclusions are as follows: (1) In the evolution of ecological space in Nanhai District from 2010 to 2020, government power is the main driving force for the evolution of urban ecological space; (2) The rent of ecological land is generally low, and the impact of market power on urban ecological space is not sufficient. It is difficult to promote the implementation of ecological space only through land rent. This paper proposes to establish an ecological spatial network that takes into account ecological benefits and economic costs. It is suggested to establish implementation supporting policies aimed at reducing the rent difference between other uses and ecological uses, and guide the transformation of inefficient construction land into ecological space through ecological restoration, demolition and greening.
