Urban ever-increasing development, irregular population growing up and immigrations to the cities have led to unplanned and uncontrollable urban development and changes in urban space structure. For this reasons, informed guidance, principle organization and space planning are necessary for urban sprawl and development. A complete and logical planning for urban developments includes various processes like urban sprawl and resources, natural and human capitals without any bias or environmental rudeness that takes each of them into consideration which is required to use exact and update data. Planners are able to recognize natural and human environment changing with  ombination of different information. They can plan future priorities based on present conditions. Despite the awareness of undesirable effects of urban development on natural environment we must accept the fact that the urban development is inevitable. However urban growth (vertical) can meet some part of needs, Dominant development takes place in suburban where land use development caused exhausting the high quality of lands and destroying sensitive ecosystems. The urban development aim is increasing urban scale and so causing juncture in natural and artificial environment. Therefore such developments must be controlled and they are led to the correct directions, locations and achievement to other goals (such as socio– economic problems that were caused migration) in urban development (Habibi, 2001).
