【Abstract】 The present situation of saline soils and the features of plant community in Yel low River Delta region were analyzed. The principal points and the applying exte nt of techniques to restore plant community were discussed. The techniques layin g emphasis on soil amelioration include site preparation, fishing in ditches, lo osening soil deeply, chemical amelioration as well as planting salt-tolerant her bs.
