Abstract:

The Arab Plateau, where the Munzur Kireçtaş and the Alibonca Formation's marnly-kumlu kireçtaş are placed, is an area where naked and thin karst develops. But depending on the litostratographic differentiation, the character of charstilization differs between litological units. Although the process of chartering has been interrupted from time to time throughout the geological history due to tectonic regime differences and climate change, the process has continued. Over time, the effectiveness of karstling has slowed down, fluvial stretching and mechanical dissolving have become more active, the formations of lapia and dolin have been destroyed. When this natural destruction is combined with the formation of thick karst, a stone land has emerged, limited in terms of water existence, soil formation and vegetation, challenging in terms of human life and human activities. Due to this current state of the area, there are almost no permanent settlements in this part of the platon, and because agricultural activities are limited, the use of the land is only carried out as a widespread area. In accordance with the purpose and objective of this study, a series of CBS-based spatial statistical analyses have been submitted, by numerizing the forms of carstitis in accordance with the practical and simple random sampling methods, to determine the restrictive and determining effects of carstitis on settlement selection and land use. As a result of the analysis, it has been statistically determined that carstling is a restrictive and determining factor on the choice of settlement and land use.

Abstract:

The Arapgir Plateau, where the Munzur Limestones and the marly-sandy limestones of the Alibonca Formation are outcropped, is an area where bare and shallow karst structures develop, as in the general of the karst plateaus. However, the character of karstification differs among lithological units depending on lithostratigraphic differentiation. The karstification process has been interrupted throughout the geological past due to tectonic regime variations and climate changes and has tended to stagnate today. Thus, karstification was replaced by fluvial erosion and mechanical dissolution, and lapia and doline formations were damaged. The combination of this natural destruction and shallow karst formations has resulted in a stony terrain that is limited in terms of water availability, soil formation and vegetation, and challenging in terms of human life and human activities. Due to the current conditions of the area, there are almost no permanent settlements in this part of the plateau and since agricultural activities are limited, the land is used only as highland-grassland areas. In line with the aim and target of the present study, karst erosional patterns were digitized in accordance with applied and simple random sampling methods and subjected to a set of GIS-based spatial statistical analyses to determine the limiting and determining effect of karstification on settlement selection and land use. As a result of the analyzes carried out, it was statistically determined that karstification is a limiting and determining factor on settlement selection and land use.
