Urban green spaces as an important contributor can be a significant part of sustainable development. Developments of urban green spaces need to consider interdisciplinary and integrative approaches such as economic, political, social, cultural, management and planning aspects to improve existing urban green spaces’ facilities and services, and to optimize urban green space policies [1]. The definition of urban green spaces which is agreed on by ecologists, economists, social scientists and planners is public and private open spaces in urban areas, primarily covered by vegetation, which are directly (e.g. active or passive recreation) or indirectly (e.g. positive influence on the urban environment) available for the users [2]. Based on the studies of different cities, different researchers provide some guidelines to evaluate the nature of green spaces. Firstly, one of the main factors in determining the nature of green spaces is their quantity in the

city [3]. Secondly, existing qualities like activities and experiences, and perceived benefits to the users determine the utilization of green spaces [4]. Thirdly, the functionality of those green spaces is equally influenced by the location and distribution (accessibility) in the whole city [4-6].
