Abstract: The accumulation and allocation of salt contents in four plant communities in Tianjin strand ecological protective circle were studied．The results show that excluding leaves and floor，the annual total storages of K ，Na，Ca，Mg and CI are 343．89kg／hm² in herb community，59．79kg／hm² in tree-shrub-herb compound storied community，55．46kg/hm² in shrub，18．87kg／hm² in shrub-herb community．The annual storages of Na and CI in the four communities are respectively 60．22kg／hm² and 218．35kg／hm²，2．385kg／hm² and 11．76kg／hm²，3．95kg／hm² and 16 74kg／hm²，2．04kg／hm² and 5．775kg／hm²．The allocation patterns of salt contents in organs of different plants are different．trees accumulate salt by root dominantly，but brushes by root and branch at the same time The proportions of total salt storage in different layers in compound storied community are also different．they are tree>shrub>herb in tree-shrub-herb community and shrub>herb in shrub-herb community．
