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.

结果显示，滩涂湿地的面积在逐年变小：从1987年的19705.09 hm2 锐减到2002年的4773.08hm2，减少了75.78%；并且滩涂湿地面积的年减少率为995.47 hm2/a，比年围垦率的729.08hm2/a增加了36.54%。
