Abstract: Based on a survey of the community type and distribution of vegetation resources in Fujiancoastal areas,a basic model is proposed to transform the current simple-structured shelterforest into a shelter forest system with herb,shrub,tree communities and various cerealcrops.The mutualistie relations among the components of forest are preliminarily discussed.Practicable measures include developing agriculture in the shelter forests,transforming threekinds of herb communities into sand-holding grazing land and growing medical crops inthe coastal sand areas.
