系统工程是20世纪中期发展起来的一门新兴的管理工程技术学科。它是以系统工程思想为指导,定性、定量相结合,各种理论、方法与技术综合集成,以系统整体最优为目标来研究系统的规划、设计、开发、生产、组织、管理、调整、控制与评价等问题的一门交叉科学。它对于农业用水具有很大的指导作用,特别是对与现在中国这种缺水的现状下的节水农业的应用和灌溉制度的优化,作物生产函数的各参变量的确定都有着重要的作用。
Systems engineering is an emerging discipline of management engineering developed in the mid-20th century. It is based on the thought of systematic engineering, combines qualitatively and quantitatively, integrates various theories, methods and technologies, and studies the planning, design, development, production, organization, management and adjustment of the system with the goal of optimizing the overall system. Control and evaluation of a cross-cutting science. It has a great guiding role for agricultural water use, especially for the application of water-saving agriculture and the optimization of irrigation system and the determination of each parameter of crop production function under the current shortage of water in China .
