Abstract: The halophilous vegetation is composed of halophytes and some plants with saline tolerance and belongs to the intrazonal vegetation. It is very poor in flora and complex in geographical elements. There are about 203 species of wild vascular plants belonging to 43 families and 134 genera. Among them 133 genera of seed plant can be divided into 13 areal-types. The cosmopolitan genera and species are dominant. It is relatively rich in littoral flora and halophytes. The physiognomy of the halophilous vegetation is sparse and low, the seasonal variety of aspect is obvious, and the layer structure is simple. The distribution and succession are closely related to the ecological factors and show obvious regulation. The succession is caused by the changes of the moisture, salt and humus content of soil and is exodynamic.

Key words: shrub, water content, live combustible, model, Maoershan Mountain.
