The result showed that the size of mud flat wetland decreased rapidly: from 19705.09 hm2 in 1987 to 4773.08hm2 in 2002, a 75.78% drop in 15 years. In addition, the annual reduction rate of the mud flat wetland size was 995.47 hm2/a, which was 36.54% more than the annual reclamation rate, 729.08hm2/a.
