Research on water ecological security in alar section of tarim river basin

Abstract As the mother river of southern xinjiang, the tarim river is the lifeline of the economy, natural ecology and the lives of people of all ethnic groups in the southern xinjiang oasis. Alar city is located in the upper reaches of the tarim river, with arid climate, scarce precipitation throughout the year, strong evaporation, lack of water resources, and fragile ecological environment. The deterioration of the water quality in the tarim river basin, the sandification of the revetment, the serious soil erosion, and the deteriorating ecological environment have become the main factors restricting the sustainable development of the social economy and ecological environment of alar city. This research investigates the current situation of the ecological environment of the tarim river basin, and makes the following research on the alar section of the tarim river through GIS spatial analysis:( 1 ) Construct an ecological corridor in the study area;( 2 ) Designate an ecological protection zone; ( 3 ) Shaping the pattern of water ecological security; (4) The task of ecological restoration is determined in order to provide a theoretical basis and scientific basis for the comprehensive development and utilization of resources in the tarim river basin, soil and water conservation, and ecological environment protection.
