There are 6 popular vegetation types: 1) Sonneratia casaeolaris L., 2) Sonneratia casaeolaris L. - Nypa fruticans Wurmb - Avicennia officinalis L. - Kandelia candel L. Druce, 3) Sonneratia casaeolaris L. - Phragmites karka (Retz.) Trin. ex Steud, 4) Phoenix siamensis Miq., 5) Sonneratia casaeolaris L. - Nypa fruticans Wurmb, 6) Nypa fruticans Wurmb. In the mudflats, soils are not mature, and pioneer vegetation species is usually Sonneratia casaeolaris L On land accreted for years the soil maturity increases, vegetation species such as Avicennia officinalis L., Kandelia candel L. Druce, Nypa frutiicans Wurmb are present. Keywords: physical and chemical characteristics of soil; vegetation along river; alluvial ground; accretion land.
