城市绿地系统多功能协同布局模式研究

摘要:城市绿地是构成城市空间形态的重要元素,在城市综合效益的发挥中起到越来越重要的作用。绿地分布应符合市民行为特征要求、改善城市生态环境、创造城市景观特色。基于绿地在游憩和防灾避险、生态和景观等各方面的功能协同作用机理,以多功能协同为目标,探讨了城市绿地节点与廊道在空间上的均衡合理配置,提出了一种能综合发挥城市绿地各方面功能、网络化的绿地系统布局模式。

ABSTRACT: The green space is an important element in city spatial form construction, which plays more and more important role in prehensive efficiency of the city. The distribution of green space should conform the public behavior characteristics of citizens, improve ecological environment in the city and create landscape characteristic of the city. Based on the synergistic effect mechanism in recreation, disaster shelter, ecology and landscape function of the green space, and taking multi-function coordination as the goal, the balanced and reasonable configuration of the green nodes and corridors in the city is discussed, and working layout pattern of green space system, which can play functions of the city green space in integration, is pointed out.
KEYWORDS: Green space function; synergistic effect; layout pattern; green space system

城市绿地的建设应追求艺术性、生态性和社会性三方面的协同发展,在重视大众游憩生活需求的基础上,融入生态和美学理论,以功能协同为目标,构建满足各种功能要求的绿地系统,从而提高城市绿地的综合效益。目前,国内外对生态机理影响绿地布局的研究较多,主要从绿地改善城市空气质量、减少城市热岛效应的作用机理方面分析了绿地的布局结构与相关指标,对绿地布局具有实际指导意义[1-3],还有依据景观生态学理论探讨基于生态安全格局的绿地系统布局[4];而根据游憩需求分析绿地布局结构的研究较少,现有研究较多集中在以服务半径判断游憩绿地的可达范围,未深入研究市民的实际出行路线对可达范围的影响[5-6],在布局上仅是原则上强调以游憩节点与廊道构成游憩网络[7]
