T he biggest value of D appeared near Guandishan, and subsequent near H aili, Keca2 T he values of vertical changes of H, J and d are the low 2tide area > the m id2tide area > the h igh2tide area, and D is in reverse. T he values of H and J are the h igh2 est in sp ring and the low est in autum n, d is the h ighest in summ er and the low est in w inter, and D is the h ighest in autum n and the low est in sp ring. T he comm unity types of benth ic in2 vertebrates of Beiji Islands are belong to the typ ical off2shore and h igh2salty one.
