Abstract:: On the basis of actual investigation and analysis of water resources utilization and agricultural irrigation water in the Keerqinzuoyizhong Banner of Tongliao City in Inner Mongolia, according to the principle of method of initial and ending calculation, then choosing some typical sample irrigation districts, which represent the different form of irrigation and carry out the relevant field test, we calculate the irrigation water use efficiency of the typical sample irrigation objectively and scientifically with the method of water balance and field measurement,respectively, the utilization efficiency of irrigation water in Keerqinzuoyizhong Banner. Through the test and evaluation in agricultural irrigation of different types of field under different irrigation technology and irrigation water use coefficient, the main irrigation methods of sample irrigation districts are low pressure pipe irrigation, sprinkler irrigation and drip irrigation under plastic film, utilization coefficients of irrigation water are 0.865, 0.874 and 0.906, respectively. Under the comprehensive factors of the hydrological and meteorological conditions, the irrigation system and irrigation management in 2014, the water use coefficient is 0.880 in Keerqinzuoyizhong Banner. The calculation results are in accordance with the actual situation in the irrigation district in order to enhance the utilization efficiency of irrigation water better and develop water-saving irrigation district further, and offer the basis of decision.
