南通市沿海滩涂变化监测研究 Dynamic Monitoring of Coastal Tidal Flat Change of Nantong City

自然海岸带环境复杂多样，变化较快。为了得到江苏省南通市近年来的沿海滩涂变化信息，本文利用Landsat卫星获取的2000、2009、2014年遥感影像，分别得到三年的海岸线和人工围垦滩涂边界线，对南通市沿海滩涂近年来的变化进行分析研究。通过对人工围垦滩涂边界的提取，得到近几年滩涂围垦的面积和年增加量。本文研究将为滩涂资源的保护和后期进行可持续地开发滩涂资源提供科学依据。 The environment of natural coastal zone was complex and varied rapidly. In order to get the information about the change of coastal beach in Nantong city in recent years, we used the Landsat remote sensing images in 2000, 2009 and 2014, respectively. The coastlines and artificial reclamation of these three years were analyzed. By extracting the boundary line of artificial reclamation, the reclamation area and increase the amount of years could be obtained in recent years. This study provides a scientific basis for the scientific protection and the later sustainable deve- lopment.
