Abstract
Bidkhan inactive stratovolcano lies at 40 km southest of Bardsir in Kerman Province between
56     26 to 56     30 eastern longitude and 29           35 to 29     40 northern latitude and it is 400 km2 in area. This paper deals with the geoecology of this volcano. For this purpose, after introducing the geoecology discipline, first, geology and topography of this volcano are described. Afterwards, the influence of this volcano on climate, hydrology and vegetation of the area is discussed. And finally its influence on human life is explained. Accordingly, due to the presence of this volcano (as a positive landform), the annual precipiatation has increased about 13 million m3 and the annual temperature has decreased about 4C . So climate of the area has change so that Dommarton index has increased  from 15 to 28. In accordance with the climatic change, which has been an increase in precipitation and decrease in temperature, the conditions changed and become appropriate for the creation of a humid valley and a semi-permanent stream draining in its caldera. Also, the vegetation over the stratovolcano has become much denser.
These conditions has led to establishment of several villages in the above – mentioned valley which, as a result of lacking convenient surface for cultivation and also cold climate, depend only on cultivation of nut trees in the valley and herdering on convenient pastures at the surface of the volcano. Hence, the presence of this volcano as a positive landform, has helped human residence and influenced the location of residential areas and human life.
