II SUMMARY Masters Thesis "Determination of Land Use Changes in Basin of Hazar Lake (from 1956 to 2004)" Celalettin DURAN University of Fırat The Institute of Social Secience And Postgraduate Study in Geography ELAZI?-2005, Page : VHI + 83 The Basin of Hazar Lake with its ecological situation, natural beauty and suitable potential for tourism which takes part in watery lands should be protected very well. Especially badly constraction, rising pollution and its drainage problems are the threats for the basin. The purpose of this study was to determine how land use forms have changed Basin of Hazar Lake (from 1956 to 2004). Prior to this study, has been selected around Hazar Lake topografic maps (1/25000), forest management maps (1/25000), soil maps (1/100000) and Aster satalite data from 2004 was obtained. All the datas, were transfered to computer by digitalling. Then digital results were obtained. How land use forms have changed the Basin of Hazar Lake by TNTmips and different GIS software were designated. The Hazar Lake Reservoir covers 27490 ha. area. Soil is under heavy erosion affect due to insufficient plant coverage and is getting shallow. The sediments carried by erosion are being accumulated in the very bottom of the lake. The capacity of the Hazar Lake reservoir has significantly reduced in the last 50 years. Afforesttion has started since 1960. By this way, the rate of forested area increased but it did not reach the rate that was thought or planned. On the other side, most of the wooded areas are not good enough. The agricultural lands have not enlarged and increased. There is rapid occupation for tourism purposed settlements, especially around Diyarbakır road and the town of Sivrice. Most of Hazar Lake Basin's soils are bare or consist of rangelands. Owing to unsuccessful afforestation and reduces on lake water level, utilize of this lands for pastoral purpose have increased.
