水利工程的建设目的主要有两个方面:一是防洪减灾;二是提供生活用水以及农田灌溉。防洪减灾属于偶发性问题,目前,水利工程大多是用于农田灌溉方面,它在其中起着不容忽视的作用。由于我国水资源极度短缺,不管是在生活用水还是农田灌溉,节约用水一直是我们用水理念,尤其是在农业灌溉过程中,节水灌溉,合理的利用水资源是政府及人民重点关注的问题。所以,在农田灌溉过程中,农民需要掌握各种灌溉技术,从而将水的利用价值充分发挥出来,以达到有效的节约经济成本,保护生态环境的目的。现主要分析了农田水利工程节水灌溉的作用,以供大家参考。
The purpose of water conservancy construction mainly in two aspects: First, flood control and disaster reduction; second is to provide domestic water and farmland irrigation. Flood control and disaster mitigation are sporadic problems. At present, most of water conservancy projects are used for irrigation of farmland, which plays a role that can not be ignored. Due to the extreme shortage of water resources in our country, water saving has always been our concept of water use, irrespective of whether it is used in domestic or farmland. Especially in the process of agricultural irrigation, water-saving irrigation and rational utilization of water resources are issues of major concern to the government and people. Therefore, in the process of farmland irrigation, farmers need to master various irrigation technologies, so as to give full play to the value of water utilization so as to achieve the goal of saving economic costs and protecting the ecological environment effectively. Is mainly analyzed the farmland water conservancy project water-saving irrigation function, for your reference.
