摘要
绿色空间系统以其综合的生态、娱乐、文化和历史功能对城市具有重要意义。当前气候变化、生态恶化、城市化等问题越来越严重,城市绿色空间系统被作为绿色基础设施的主要部分来应对这些问题。因此,对于城市绿地系统规划模式的研究非常必要。纽约中央公园在城市中心引入了巨大的绿色空间,开启了城市的绿心模式。在这个模式中存在着等级结构,大型绿色空间处于顶部,而小型空间处于底部。大型绿色空间对于城市具有重大的作用,而且在规划图纸上具有强烈的视觉效果,因此为规划师们所喜爱。然而,过于将城市绿地集中于少数大型绿色空间之中则对于城市产生负面影响。它破坏了城市绿色空间系统的均衡性,从而减少城市居民享受城市绿色空间系统综合效益的可能。作为一个替代方案,提出分布式城市绿色空间系统,将分布式的概念引入城市绿色空间系统规划之中,强调绿色空间在城市中的均衡分布,以使更多城市居民能够从中获益。
The green space system is important to city for its integrated and interdependent ecological,recreational,and cultural and historical considerations.As critical issues such as climate change,ecological crisis,and fast urbanization continue to increase,the green space system strategy is gaining increased implementation as a major part of green infrastructure.Thus,more extensive research is necessary on green land systems and their applicability in city.The Central Park in New York City started a city green space pattern,noted by the introduction of a large green space in the center of the city.In this pattern,there is a hierarchy of green spaces in which the larger spaces are at the top of the hierarchy and small spaces receive the least consideration.Large green spaces are believed to be more important,and are thought to provide better visual aesthetics than small spaces.Thus,this design approach has been,and continues to be preferred by planners and cloned worldwide.However,it is important to note that allocating the urban green lands into a few oversized green spaces might have a negative impact on the city in all scenarios.It causes the imbalance of urban green space system,so that less citizen can benefit from it than a balanced system.A distributed green space system might be an alternative strategy for a city＇s green space system.This paper introduces the concept of distribution to urban green space system planning,focusing on the balanced arrangement of green spaces in a city,in order to benefit more common citizens.
