摘　　要：农业是国民经济的基础,水利灌溉是农业生产的有力保障。该文对农田灌溉所需的各种关键指标进行分析,得出7类最重要的指标,并从各指标的对比分析中得出灌溉总水量最重要的结论。在此基础上,给出灌溉总水量及相关参数的数学模型和计算方法。依托理论分析和数学模型,展开实验验证。实验过程中,降水量被协同考虑,通过多组农田的灌溉总水量计算及分析结果中可以看出,水利灌溉在满足农田总需水量的前提下,受到降水量的重要影响。如果一个年份的降水量充沛,灌溉总水量就会相对减少;相反,灌溉总水量就会相对增加。可见,准确地统计区域降水量,对农田水利灌溉的合理实施具有非常重要的意义。Agriculture is the foundation of the national economy,and water conservancy irrigation is a powerful guarantee of agricultural production.In this paper,various key indexes needed for farmland irrigation are analyzed,seven kinds of the most important indexes are obtained,and the most important conclusion of total irrigation water quantity is drawn from the comparative analysis of each index.On this basis,the mathematical model and calculation method of total irrigation water and related parameters are given.Based on theoretical analysis and mathematical model,experimental verification is carried out.In the course of the experiment,precipitation is considered cooperatively.Through the calculation and analysis results of the total irrigation water of several groups of farmland,it can be seen that water conservancy irrigation is greatly affected by precipitation on the premise of meeting the total water demand of farmland.If there is plenty of precipitation in a year,the total amount of irrigation will be relatively reduced;on the contrary,the total amount of irrigation will be relatively increased.It can be seen that accurate statistics of regional precipitation is of great significance to the rational implementation of irrigation and water conservancy irrigation.
