In the present era, the importance and role of green space in the life and development of cities are to the extent that it is mentioned as one of the indicators of sustainable development. In sustainable urban development, proportional distribution of green space according to the balanced distribution of the population is one of the principles of establishing geographical justice. The purpose of the present study is also to determine the status of green space per capita in ten districts of Shiraz city. The research type is applied-developmental and the research method is descriptive-analytical. The data has been collected from urban plans, and to investigate the spatial distribution of the share of green space in 10 districts of Shiraz city, Dispersion coefficient model was utilized. Shannon entropy also has been implemented for analyzing Population distribution during 2007, 2012 and 2016 in urban districts of Shiraz. The research results show that the highest per capita of urban green space is related to districts 9, 3, 6, 1, respectively, and the lowest per capita of green space is related to districts 8 and 7, respectively. The coefficient of dispersion was obtained as equal to 0.20, which, unlike the previous studies, indicates the realization of the principle of justice in spatial planning of green space index in 2016. The results of the entropy coefficient showed that distribution of the population in ten districts of Shiraz in 2007 has been balanced, in 2012 has moved toward unequal distribution of population, and then in 2016 again has moved toward balanced distribution.

Advantages of urbanization such as access to clean water, health, and overall easier life in cities, as well as the disadvantages or its negative effects on environment cannot be ignored. Today, there are numerous environmental problems due to the reduction in ecologically valuable places within urban areas. Bringing nature to the cities appears to be essential to enhance urban environment and to reduce environmental problems in urban communities. In fact, issues resulting from the idea of "sustainability" as a policy-making goal require an integrated environmental policy-making approach. The innovations of new environmental policy-making require policy-making mechanisms that can deal with interdependent characteristics of environmental problems. To this end, new structures have emerged known as Environmental Planning and Management and Strategic Environmental planning and management. This analytical – descriptive article aims to re-examine the origins and concepts related to environmental planning using a field and desk study. With the introduction of urban natural landscape, Environmental planning considers such spaces within the city. In this regard, Khoshk River, Shiraz, Iran, as an urban natural landscape, was analyzed. Environmental planning-based polices were proposed to improve quality of the place under discussion.
