Abstract

Valleys as the major components of the land structure (Ecological corridors and settlement patches) play a major role in providing environmental services and values to the adjoining areas. Tehran has a specific geographical and ecological setting which stems from Elborz mountains and nearby mountaneous valleys. These valleys, in addition to the purification of air, and water production, are regarded as picturesque views of the city of Tehran.
As the land consists of different ecotop and phsyiotop units, therefore, each unit has its own special environmental conditions that forms land structure graining.
Any change to the existing landuse of these valleys would result in changes in the land structure. For prevention of destruction of functional values and suitable uses of natural characteristics of these valleys, studies of environmental issues of this natural structure become essential.
In this research among others Farahzad valley was selected as a case study. A thorough field study and examination of existing documents, resulted in proposals for the optimum land uses of the natural setting in two macro-micro scales within the city.
For creation of a balance between urbran spaces and nature, and users of the spaces and the nature, suitable land-uses have been proposed. The proposed landuses provide the provision of the use of the natural space by citizens, and also protection of urban natural spaces within the city.
