城市绿地的作用被广泛认为对健康具有积极影响并在城市中提供一整套生态系统服务。本文提出了一个城市绿地规划框架，考虑了不同社会群体（例如儿童和老年人）对可达性的需求和偏好。它旨在实现绿地规划和设计方面的不同目标，并用于不同的城市环境。该框架分为四个阶段，在绿地规划过程中进行：目标的定义、新的或现有绿地的可达性建模、结果的解释和规划决策的定义。在该框架中，绿地的可达性通过基于地理信息系统的空间明确指标进行评估，这些指标将社会经济和土地利用数据与道路网络信息相结合，从而考虑到社会需求与城市中绿地存在之间的相互作用。该规划框架针对卡塔尼亚（意大利）和名古屋（日本）城市提出了两种应用，其特点是不同的绿地配置、高城市密度城市和特定社会群体的存在。介绍并讨论了两个案例研究强调的规划意义。
The role of urban greenspaces is widely considered having positive implications for health and providing a complete set of ecosystem services in cities. This paper presents a planning framework for urban greenspaces that considers demands and preferences for accessibility of different social groups (e.g. children and elderly people). It is designed to achieve different objectives in terms of planning and design of greenspaces and to be used in different urban contexts. The framework is structured in four phases that take place during a planning process of greenspaces: the definition of the objectives, the modelling of accessibility to the new or existing greenspaces, the interpretation of results and the definition of planning decisions. In the framework, accessibility to greenspaces is assessed through spatially explicit GIS-based indicators that combine socio-economic and landuse data with the road network information, so to take into account the interactions between social demands and the presence of greenspaces in cities. Two applications of the planning framework are proposed for the cities of Catania (Italy) and Nagoya (Japan), characterized by different configurations of greenspaces, high urban density urban and presence of particular social groups. Planning implications highlighted by the two case studies are presented and discussed.
