AFFECTS DETERMİNATİON OF THE NATURAL FACTORS SUCH AS CLİMATE, SOİL, VEGETATİON AND GEOMORFOLOGY ON LANDUSE/COVER BY HELPİNG GEOGRAPHY İNFORMATİON SYSTEM (GİS) İN THE KESİS STREAM BASİN (SOUTH OF TURKİYE)

There is a close interaction between any natural environment and especially human beings and other living things. This interaction; It controls landforms, climate, soil and vegetation. Climate is the most important external force that shapes the earth. For these reasons, human beings; It maintains its life in the natural environment by adapting to the landforms and climate. The behavior of human beings to adapt to nature has emerged as land use. In this study; Landforms, climate, soil and vegetation that are effective on land use in Kesis Stream Basin were examined. In the study, geographic information systems (GIS) were chosen as the method, and the elevation model, other data obtained from the institutions constitute the study materials. These data were processed through GIS and explained visually and numerically.Accordingly, it has been determined that the rugged landforms of the basin do not allow settlement and agricultural activities since they correspond to approximately 80% of the area (Table 3). In the basin, brownish forest soils and red Mediterranean soils developed, in which Mediterranean climate characteristics are observed. On these soil surfaces; conifer, mixed and broad-leaved plant species showed a wide distribution. While alluvial and colluvial soils developed on landforms such as polje, uvala, and sinks in the basin, it was determined that these surfaces were used as settlement and agricultural areas. As a result, it was determined that more than 70% of the area (Table 6) limited settlement and agriculture in the Kesis Stream basin, as a natural result of the mutual interaction of landforms, climate, soil and plant characteristics. Apart from these, it has been determined that about 17% of them, such as the accumulation fan, polje, uvala, doline, low plateau, are engaged in settlement and agriculture. Here; the rules of natural factors should be prioritized and land use plans should be made to adapt to this.
