According to geomorphic systems affecting the settlement of areas, including in the planning and urban management. Due to the geographical location and structural the Kerman and performance of various systems of agents, such systems are alluvial, Aeolian and morphotectonic Implementation and management of all development plans need to be obsessively this space very carefully done. The incidence of serious risks such as ground subsidence, loss of water resources, tectonic activity and Aeolian processes in the atmosphere is solid evidence of this claim. Kerman is located at a point that many factors can affect its normal study of factors influencing the reduction of environmental hazards can be effective. The purpose of this study demonstrates the effect of natural factors and the impact of Kerman urban development on the intensity of negative factors affecting external. This research is trying to use GIS techniques to evaluate geomorphic systems the Kerman range of factors influencing the mapping of processes to check. The results show that morphotectonic systems, including Fluvial and Aeolian systems are effective the Kerman. The maps show that the levels of native lands, and large parts of the Kerman planar surfaces with low slope and covered with alluvial deposits and clay zones form. This can have a considerable impact on the intensity of risks.
