河北省是资源型缺水省份,干旱缺水已成为制约经济社会可持续发展的瓶颈。黑龙港地区微咸水资源相对丰富,具有埋藏浅、易开采、补给快等特点。省水利厅经过多年的试点研究,利用微咸水和深层淡水混合灌溉技术逐步成熟,从2005年开始在该地区大力推广,同时相继出台了发展规划和技术标准,有效地规范了咸淡水混合灌溉工程的建设发展。本文从咸淡水混合灌溉工程发展现状、工程发挥的效益以及下一步发展的思路和措施等三方面进行了阐述。
Hebei Province is a resource-poor province. Drought and water shortage have become the bottlenecks restricting the sustainable economic and social development. Brackish water resources in Heilongjiang area are relatively rich, with shallow burial, easy exploitation, fast supply and so on. After many years of pilot research, the provincial water conservancy department has gradually matured the technology of using brackish water and deep freshwater mixed irrigation and started to promote it in 2005. At the same time, it has successively issued development planning and technical standards to standardize the irrigation of fresh and brackish water Construction and development of the project. This article elaborates from three aspects: the status quo of the development of mixed irrigation of brackish water and freshwater, the benefits of the project and the ideas and measures for the further development.
