Preventing Ggeomorphologic Factors in Spatial Logistics in Lar City

Larestan City is a memorial of ancient Iran the date of whose dwelling reaches over 3 thousand years ago. Its growth during this long period has encountered both ascending and descending trends. Its strategic situation has caused a considerable growth in settlement due to its adjacency to the establishments of great oil projects in Assaluyeh-Parsian and Dallan Ports on the one hand and proximity to goods input and output transportations on the other hand. Nevertheless, there seems an urgent need for the cession of lands and a change of utilization.
Of course, though such changes occur with special outcomes most of which have a negative aspect and nature, we can move towards a stable development with an understanding of the areas and analysis of dominant parameters as well as an optimal use of sciences and new technologies. It is completely clear that geography and its major branches such as geomorphology as a specialised and applied science play an important role in this process since cities are always under its influence and their formations mostly occur in an environment which is under the function of geomorphologic phenomena. Moreover, cities along with their increasing developments encompass different geomorphologic and topographic terrains. Thus, there is a possibility that cities take the influence of geomorphologic phenomena and other problems due to them more than before. In this confrontation, if we do not observe some necessary points and principles, a disturbance occurs in morph dynamic balance and great dangers threaten cities. It is even probable that sometimes the severity of such perils and disasters reach an extent that they cannot be compensated. Such phenomena as floods and river overflows, different types of mountain slope movements, earthquake consequences, etc which continually threaten cities are of those factors depending on geomorphology directly or indirectly. In this scope, we have tried to identify preventing geomorphologic factors for this city which is considered as an important commercial-cultural centre located in the southern part of Iran.
