摘要：
The utilization degree of irrigation water is the key indicator of agricultural water-saving efficiency. Currently, water efficiency of irrigation is used to reflect the utilization degree of irrigation water, people commonly uses hydrodynamic measurement and static water measurement, but the result is still affected by many factors. This thesis is based on the method of extenics that combines with various kinds of irrigated area characteristics, realizes the comprehensive evaluation of irrigation and irrigation water utilization. And a simple example shows that is more reasonable compared with traditional methods.
