【摘要】 文利用K-T变换改进后的谱间关系法对辽东湾的遥感数据进行分析,确定水陆分界,提取不同时期的海岸线,将不同时期的海岸线叠加分析岸线变化的趋势;利用ArcGIS的空间分析功能,计算不同岸段的岸线变化的面积和速率并对其稳定性进行了研究,发现不同岸段的稳定性不同:双台子河两侧岸段和小凌河西侧岸段稳定性差,岸线变化剧烈;大凌河西侧岸段变化较为剧烈;大小凌河东侧岸段和大辽河西岸岸段稳定性好.辽东湾北部岸线变化原因复杂.更多还原

【Abstract】 The relationship of K-T transform between the improved method of spectral remote sensing data in Liaodong Bay were analyzed for extraction of different periods of the coastline,the coastline of the superposition of different times to analyze trends in shoreline change;use ArcGIS for spatial analysis,calculation of different segment of the coastline shore area and the rate of change and its stability was studied and found that different deposition rates of different coast,Liaodong Bay in the direction of regional changes in the coastline is mainly silt into the sea,but the stability of various different coast.更多还原
