青岛盐碱地盲管排盐与绿化改造技术的研究

为适应经济社会的快速发展,青岛市加大了对沿海滩涂地的开发利用,对盐碱地绿化改造的技术措施的需求也愈来愈迫切。在对山东省、天津市等地盐碱地改造措施调研考察的基础上,结合青岛市滨海海涂地的实际情况设计出盲管排盐和隔盐层相结合加客土置换的土工改造措施,盲管与排水系统相接,达到排水排盐作用。在工程排盐的同时,应用不同的绿化改造技术,筛选耐盐碱植物树种,施用改良肥、苗木的栽植方式等,可有效地减少地面水分的蒸发,降低地下水位,并抑制盐碱的上移和积累,形成良好的生态循环。

Techniques of Removing Salt by Tile Drain and Afforestation in Saline -Alkali Shoals and Marshes of Qingdao City

With the development and utilization of Qingdao's coastal shoals and marshes,it becomes increasingly necessary to develop appropriate and effective techniques of afforestation to ameliorate the saline-alkali land.Based on the measures and experiences of ameliorating coastal saline-alkali land of other regions such as Dongying of Shandong Province and Tianjin City,considering the local conditions in Qingdao City,we have put together a suit of measures to removing salts including tile drain,salt impeding laye...
