第一章农业节水灌溉概述

1.1节水灌溉的意义与现状

1.1.1节水灌溉的意义

我国人口增长、经济发展和城市化进程的加快，水资源供需矛盾日益突出，水资源已成为制约农业发展的关键因素。农业节水灌溉作为一种有效的水资源利用方式，对于缓解我国水资源压力、保障粮食安全、促进农业可持续发展具有重要意义。

节水灌溉的核心在于提高农业用水效率，减少无效蒸发和渗漏，优化水资源配置，实现农业可持续发展。具体而言，节水灌溉具有以下意义：

（1）提高农业用水效率，降低农业用水量，缓解水资源供需矛盾。

（2）改善农业生态环境，减轻农业面源污染。

（3）促进农业产业结构调整，提高农业经济效益。

（4）提高农业抗风险能力，保障粮食安全。
