Calculation Method Improvement of Single Measure Water-saving Quantity in Comprehensive Water-saving Reconstruction for Irrigation Areas
The irrigation areas water-saving reconstruction often adopts many kinds of measures synchronously, and irrigation areas water-saving quantity is the comprehensive effects of all single measures. The present water-saving calculation method, which is unable to satisfy the practical developments needs, has deficiency in evaluating the contribution of concrete water-saving measures to the comprehensive water-saving quantity. Therefore, it is necessary to develop a set of computation methods, which is able to reflect the water-saving effect of a single measure, also express the synthetical water-saving quantity. This article analyzes various links water demand from water source to the crops absorption and the principles of water-saving measures, combines organically the water-saving quantity of a single measure method and the overall method, and proposes a set of calculation methods with no repetition and really reflecting the real water-saving contribution of each single measure.
