Result shows that (1) Eucalyptus dunnii Casuarinn equiestifolia have good adaptability to climatic site conditions of island; wind resistance of Casuarinn equiestifolia is greater than that of Eucalyptus dunnii; ( 2 ) altemation of forest and cottons can reduce soil salinity and increase economic benefits; (3) adopting banded structure of windbreak of evergreen deciduous species ,trees shrubs not only have significant protection function , but also have goo
