The soil texture

pH

salinity

organic matter

groundwater level and mineralization degree in Bohai sea coastland in Xinhu village

Dongying city

Shandong province and in Yellow sea coastland in Xuwei salt field

Lianyungang city

Jiangsu province are investigated

measured and analyzed. According to soil physicochemical properties

groundwater lever

and the ability to endure salinity and humidity

different species of seedling to plant in different area in Xuwei salt field is chosen. The result shows that Ziziphus jujuba is more fit to climate

soil and groundwater level in Bohai sea coastland and gain good economic and ecological benefit; Ziziphus jujuba

Amorpha fruticosa

Populus L.

Melia azedarach

Koelreuteria paniculata

Pteroceltis tatarinowii

Eucommia ulmoides

Sophora japonica

Robinia pseudoacacia

Salix matsudana

Albizia julibrissin

Ginkgo biloba are fit to conditions of Xuwei salt field and gain the basic afforestation benefit

but the chosen species of seeding and tree planting technique should be further researched in some area of the salt field.
