As urban areas increase in size, density and population, green spaces become increasingly important for sustainability and liveability. Yet urbanisation processes, compounded in many cases by climate change impacts, are placing increasing pressure on retention of urban vegetation. This paper aims to analyse the role of local government policies in provision of urban green spaces.

The research focuses on policies of three neighbouring local governments in Melbourne Australia, representing inner, middle and outer urban contexts. The paper applies Transition Management’s four spheres, strategic, tactical, operational and reflexive, to structure the analysis.

The research identified key policy success factors and related these to the four spheres of analysis. The research found that a key limitation to a consistent or unified approach to green space provision is the ‘splintered’ or competing narratives that are applied to the functions, benefits and characteristics of urban green spaces. This fragmentation slows transition to nature-based cities.

随着城市规模，密度和人口的增加，绿色空间对于可持续性和宜居性变得越来越重要。然而，在许多情况下，由于气候变化的影响，城市化进程给保持城市植被带来了越来越大的压力。本文旨在分析地方政府政策在提供城市绿地方面的作用。

该研究的重点是澳大利亚墨尔本三个相邻地方政府的政策，代表了内部，中间和外部城市环境。本文运用过渡管理的四个领域（战略，战术，运营和反思）来构成分析。

该研究确定了关键的政策成功因素，并将这些因素与分析的四个领域相关联。研究发现，一致或统一的绿色空间供应方法的关键局限性是适用于城市绿色空间功能，效益和特征的“碎片化”或竞争性叙述。这种分裂减缓了向自然城市的过渡。
