摘要
本文利用NOAA／AVHRR的1、2通道遥感资料的比值模式，生成沿海地貌数值图，通过二次最优二分割方法确定涨潮落潮下的水陆分辨阈值，并分析了高低潮位下的海涂面积和外海沙脊的变化情况，供开发海涂资源参考。
In this paper，the numerical picture of the Nantong coastal landforms is formed by using the ratio model（CH2／CH1） of the remote／sensing data from NOAA／AVHRR and the threshold distinguishing the water and land under ebb and flow of the tide Is defined respectively by using the method of' optimum cutting apart'． Inthe end， theseabeach area under high tide and the variation of the sand ridge in outer sea under low tide are discussed．The results obtained can provide reference for the seabeach developer．
