quantitative identification of physical changes, developments and dynamic position of urban green space is considered as the first step in its planning. by means of the aerial photos taken in 1956, 1974, and 1994 as well as the quick bird satellite image captured in 2006, this study has dealt with changes in per capita green space in khorramabad during these years. first, geometric corrections ...

in the recent years, increasing of green house gases, degradation of environment, deforestation alongside with the limitation and decreasing of ecological foot print of the earth for supplementation of human needs are the main problems of the world. the carbon dioxide gas as a main factor of world climate change, carry out the 60 percent of the global heating or greenhouse effect. the main sour...

Soil is a vital parameter for planting design in urban green spaces especially in adverse climate conditions. In this study, the utilization of analytic hierarchy process (AHP) in surveying land suitability for urban green space from measured criteria like suitability indices, including physical (i.e. clay, silt, sand, bulk density, penetration resistance), chemical (i.e. electrical conductivit...

many epidemiological studies have found that people living in environments with more green space report better physical and mental health than those with less green space. however, the association between visits to green space and mental health has seldom been studied. the environment surrounding residences and its recreational and commuting opportunities are believed to affect human health and...

Water supply of green spaces in arid areas is a major challenge. A high percentage of green spacescreate lawns, which are high water consumer landscapes. Due to the environmental, recreational andathletic values of lawns, they are considered as non-removable elements in urban green space development.This paper reviews and discusses strategies for efficient water usage in lawn areas using librar...
