摘要:
利用1993—2011年的4景TM及HJ-1A /1B卫星影像，结合2003年水下地形图，以ArcGIS为工具，进行了渤海湾曹妃甸海域近20年来围填海工程造成的岸线变化监测和水动力环境及冲淤演变影响分析.结果表明，前10年围填海规模不大，岸线推进缓慢，围填海范围在2003年的0 m等深线以内，仅局部地区向海推进约1.3 km；后10年岸线显著向海推进，最近5年的围填海区域已经深入到2003年0 m等深线以下，但基本在2003年5 m等深线以内.目前的围填海方案对水动力影响甚微，离岸沙坝内外有冲有淤，但深槽和水道稳定性良好.针对今后10年的围填海规划方案，需要进一步加强包括遥感手段在内的现场监测研究以及渤海湾内多个围填海工程对曹妃甸海域的累积影响研究.

Abstract:
Detection of the coastline change caused by reclamation projects and hydrodynamic environmental impact analysis of the Caofeidian sea area for nearly 20 years are conducted by means of ArcGIS， and using 4 satellite images including Landsat TM and HJ-1A /1B， and the underwater geomorphologic map in 2003.Analysis results show that in the first 10 years， the coastline advances slowly， and the maximum distance to the sea in some areas is only about 1.3 km; and the reclamation scale is small， and is more limited within 0 m contour. The coastline has advanced towards the sea significantly in the last 10 years， and the reclamation area has been deepened into the 0 m contour but within the -5 m isobath. The current reclamation has little impact on the hydrodynamic environment around. Deep troughs show good stability though there is scouring and silting between the internal and external of offshore bars. According to the reclamation plan for the next decade， there is a need to strengthen the monitoring， including remote sensing means. Research of cumulative impact of several reclamation projects in Bohai Bay on the Caofeidian sea area also should be carried out in the future.
