滨海地区盐碱地园林绿化排碱施工技术

Construction technology of coastal afforestation and alkali discharging project

东营某园林绿化工程,位于东营海虹港附近原有盐田及养殖场,现为经济技术开发区用地,场区内为新填杂土,因地下水位高,新填土盐碱化严重,不适宜进行绿化施工,为尽快改善开发区形象,采用将碱土换填为种植土进行绿化.为保证新换种植土不被地下水盐碱化,确保达到长期绿化效果,在新换种植土下设置了一层排碱层.结合工程实例,阐述了在滨海盐碱地区进行绿化排碱施工的技术要点,工程实践证明,此种排碱施工技术效果良好.

An afforestation project area in Dongying lies near to the Haihong Port and in-shore fisheries,which is the Economic Development Zone of Dongying. Because of complex soil and a high water table, serious soil salinization, the project of this kind is very difficult. So in order to improve the environment of this region, it has been proved that replacement of the land with living soil finds a way out for greening. For the protection of the new soil salinization, so a layer of living soil with something is set to fight against alkali. With engineering examples, this paper elaborates the afforestation and alkali discharging construction technology points in coastal saline areas. Engineering practice has proved that such a way is good in effect.
