Detection of the ground water distribution using thermal remote sensing technique in the Kirya oasis, southern part of the Taklimakan desert, Xinjiang, China

Abstract : Kirya oasis, which lies in the southern part of the Taklimakan desert and the north foot of the Kunlun Mountains, is one of the cases that have shown the obvious degradation of ecological environment due to the intrusion of human activities in the last 50 years. Therefore, it has become one of the target areas for researching, exploiting and utilizing of water resources in the oasis. The purpose of the study is to determine the depth of occurrence of groundwater and evaluate the ground water level distribution in oasis and desert ecotone using thermal IR image data in combination with the measured groundwater level, soil temperature and auxiliary material of the research area. Based on the field measured groundwater level data and soil temperature, the related equation of surface temperature and ground water is established and the inversion quota model of ground water is elaborated using integrative means of remote sensing and mathematical modeling. The result of experimental tests of the model in the oasis and desert ecotone, Kirya County, Xinjiang Uyghur Autonomous Region shows a good correspondence, the correlation coefficient is 0.893.
