Accessibility to urban green spaces is essential for urban dwellers’ health and well-being. For planning purposes different accessibility measures and indicators have been used. Some are only based on availability, others consider distance from residences, yet others rely on gravity-based methods that consider both supply and demand. Different indicators often provide diverse and sometimes contradictory results and many issues remain in developing a comprehensive measure of accessibility, and representativity problems remain in matching indices with reality. In this study different accessibility measures have been developed and applied to the urban parks of the city of Padova, in northeastern Italy. Effectiveness and reliability of ten indicators derived from these measures, in identifying needs, inadequacies and disparities in park access have been tested at the urban unit scale. The study confirmed that multiple indicators need to be used to provide a useful planning tool for the provision of adequate and equal opportunities for open space access to the citizens. The study has also shown which indicators can be replaced by each other without losing important information.

城市绿地的可及性对于城市居民的健康和福祉至关重要。出于规划目的，使用了不同的无障碍措施和指标。有些仅基于可用性，有些考虑与住宅的距离，还有一些依赖基于重力的方法，同时考虑供应和需求。不同的指标往往提供不同的，有时甚至是相互矛盾的结果，在制定全面的可达性衡量标准方面仍然存在许多问题，在将指标与现实相匹配方面仍然存在代表性问题。在这项研究中，已经开发了不同的可达性措施并将其应用于意大利东北部帕多瓦市的城市公园。从这些措施中得出的十项指标在确定需求方面的有效性和可靠性，公园入口方面的不足和差异已在城市单元规模上得到检验。该研究证实，需要使用多个指标来提供有用的规划工具，为公民提供充分和平等的开放空间使用机会。该研究还显示了哪些指标可以相互替换而不会丢失重要信息。
