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 layers and soil replacement.In conjunction with the engineering measures,plant management techniques such as selection of salt-tolerable species,use of improved fertilizers and proper planting.Taken together,these comprehensive measurements could effectively reduce evaporation from soil surface,lower groundwater levels,impede salt accumulation in the surfaces,and therefore form a healthy eco-cycle.
