Abstract:

Earth geomorphology, urbanization, industry, transportation, mining, tourism and so on. It is exposed to anthropogenic pressures under the influence of many factors and undergoes changes in different dimensions with the developing technological opportunities. The investigation of these human-induced changes with various approaches has been the starting point of anthropogenic geomorphology studies. Anthropogenic origin in Turkey, especially in densely populated areas with different factors and processes geomorphological changes are happening. In this study, the intensity of anthropogenic geomorphological change in Maltepe (Istanbul) district and the factors played role in this change were investigated by geostatistical methods. In the research, anthropogenic originated geomorphological change density map of the study area was produced by using elevation data of 1985 and 2020, satellite images of the last 50-year period in 10-year periods, orthophotos and measurement-observation data from field studies. The factors affecting the intensity of anthropogenic geomorphological change were determined as 10 main factors and 58 sub-parameters. Regression, geographical detector, impact-factor analysis were applied to the main factors and subunits determined by the change density data and the effective factors were determined. According to the change model, it was determined that very high and high density geomorphological-topographic changes were experienced in 20.4% of the district land. Analysis results showed that land use, geomorphology, elevation, building floors and road density are the main factors of change in the occurrence of anthropogenic originated geomorphological changes.
