20世纪90年代以来,珠江三角洲各级城镇急速扩张,用以促进城市空间有序扩展的绿地系统规划因缺乏有效的管理体制而收效甚微。基于此,有必要探讨在快速城市化地区设立自然保护区的必要性和可行性,恢复城市特色,保障城市生态安全。应重新思考自然保护区的设立标准,建立一套有效的自然保护区管理体制,将自然保护区规划与城市绿化系统规划有机结合。 Since the 1990s, the rapid expansion of cities and towns at all levels in the Pearl River Delta and the planning of green space systems to promote the orderly expansion of urban space have had little effect due to the lack of an effective management system. Based on this, it is necessary to explore the necessity and feasibility of setting up nature reserves in rapidly urbanizing areas, restoring urban features and ensuring urban ecological security. We should reconsider the establishment standards of nature reserves and set up an effective management system of nature reserves to combine the planning of nature reserves with the planning of urban greening systems.
