低碳城市理念下的郑州市绿地系统优化研究

Research on Green Space System Optimization of Zhengzhou City under the Low-carbon Concept

低碳城市是一种实现低碳经济、进行低碳生产与消费、形成低碳生活、建设良性与可持续发展的能源生态体系的城市模式。通过调控城市绿地系统、优化城市开放空间,有利于低碳城市理念下的生态城市建设,实现城市的可持续发展。首先对低碳城市建设与城市绿地系统优化的关系进行了分析;其次对郑州城市绿地系统建设存在的主要问题进行了探讨,借助ArcGIS 9.3软件分析了郑州市绿地服务区的影响范围;最后基于城市绿地系统优化原则提出四方面的优化建议——注重城市的生态设计;优化绿地系统的空间布局;实现"点"、"线"、"面"的有机结合;实施适度的绿地容量限制;发展立体绿化与推广绿色建筑材料的使用。

This paper firstly analyzed the relation of low-carbon city and urban green space system, then gave a concrete analysis on the construction of green space system in Zhengzhou City, the impact areas of green space system were analyzed by Arc GISg. 3. Finally, based on the principles of ecological construction and proposed the following measures： Paying attention to ecological design of city green space system; Optimizing the space layout of green space system, archive ＂point＂,＂line＂ ,＂surface＂, containing appropriate green capacity and developing the three- dimensional landscape and promoting the use of green building.
