摘要

摘要: 海岸线是海洋与陆地的分界线，也是重要的生态交错线。本文采用GF-1卫星遥感影像，通过监测大潮高潮时刻和小潮低潮时刻海岸水陆边界线，构建了潮间带完整性系数，以此为依据将海岸线划分为自然海岸线、具有基本生态功能的人工海岸线、具有部分生态功能的人工海岸线、具有有限生态功能的人工海岸线、具有少量生态功能的人工海岸线和无生态功能的人工海岸线。在此基础上，结合潮间带完整性系数及其毗邻海岸线长度，构建了海岸线生态化指数，用以评价区域海岸线的生态化程度。营口市海岸线以无生态功能的人工海岸线、自然海岸线和具有少量生态功能的人工海岸线为主，分别占到海岸线总长度的45.74%、18.31%和15.53%。营口市总体海岸线生态化指数为0.29，其中西城区、老边区、盖州北、鲅鱼圈区和盖州南分别为0.55、0.17、0.40、0.10和0.55。

Abstract: Coastline is boundary line of land and sea, it is also an ecotone between land ecosystem and marine ecosystem. This paper employ GF-1 Satellite remote sensing images to monitor land boundary line at time of high tide and low tide, and create a tidal zone completeness index. The coastline is divided into natural coastline, artificial coastline with basic ecological function, artificial coastline with part ecological function, artificial coastline with limited ecological function, artificial coastline with few ecological function and artificial coastline with none ecological function based on tidal zone completeness index. Then the ecological index of coastline is established to evaluate the ecological condition of coastline in regional scale. The coastline in Yingkou is dominated by artificial coastline with none ecological function, natural coastline and artificial coastline with few ecological function. Their length is account for 45.74%, 18.31% and 15.53% of total coastline in Yingkou. The ecological index of coastline for total region is 0.29, and exist difference in sub-regions of Xicheng, Liaobian, Gaizhoubei, Bayuquan, Gaizhounan with value of 0.55, 0.17, 0.40, 0.10 and 0.55.
