沿海盐碱地区绿地淡水层保护系统的设计

在渤海湾某国际生态城内某校区的可持续水系统设计中,针对该滨海区域所存在的土壤盐碱化、地下咸水水位高等问题,提出了构建绿地淡水层保护系统的理念。介绍了绿地淡水层保护系统的构造、布置、部分工程细节及设计体会,着重分析了地下咸水水位控制及淡水层形成的原理,并通过地下水流模拟软件对淡水层的形成过程进行了模拟,为在沿海盐碱区域建设城市淡水系统提供技术参考。

Design of Freshwater Layer Protection System for Green Area in Coastal Saline-alkaline Zone

In the design of the sustainable water system of a campus situated in an international eco-city along the Bohai Sea,the concept of freshwater layer protection system for green area was proposed to solve problems of soil salinization and alkalization and high underground salt-water level in this coastal zone.The construction,layout,part of the project details of this system and some design experience were introduced,the principles of salt-water level control and the formation of the freshwater layer were analyzed,and the formation process of freshwater layer was simulated by groundwater modeling software,which provides technical reference for the construction of freshwater system in cities in coastal saline-alkaline zone.
