摘　　要：在曹妃甸野外调查与研究中,通过综合使用8种卫星10种类型的遥感数据源,分析不同类型数据的图像特征,结合野外验证,对地表环境现状及变化、海洋悬浮泥沙分布与变化、地面沉降变化速率、潮间带特征等展开研究,取得了预期成果。研究发现,Landsat卫星数据良好的历史延续性和光谱特性使其可以有效应用于地表环境变化、海岸线变迁、悬浮泥沙和潮间带特征等多项研究中;综合使用多源数据可以填补监测周期,提高地面沉降、海岸线特征等调查的精度;加强利用遥感技术开展潮间带特征的应用研究对开展潮间带调查工作具有积极意义。该项研究为利用遥感技术开展海岸带地质环境综合调查评价提供了重要技术支撑。Based on the field survey and research in Caofeidian,8 kinds of 10 types of satellite remote sensing data were used in Caofeidian Project. By analyzing the characteristics of different images,status and changes in the surface environment,suspended sediment distribution,land subsidence characteristics and intertidal zone characteristics were examined by combing field confirmation,and the expected results were achieved. The research results show that the historical continuity and spectral features of the Landat satellite data can be effectively used for the studies surface environment changes,shoreline changes,suspended sediment and intertidal zone characteristics. Combination of multi-sources data can complement the monitoring period,improve the precision of subsidence and shoreline characteristics. Improvement of the techniques of using remote sensing to study tidal flat is of significance for the investigation of tidal flat. The study provides technical support for using remote sensing technologies to carry out geological environment survey in coastal zone.
