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.
