【摘要】：海岸線是海洋與陸地的分界線,也是重要的生態(tài)交錯線。本文采用GF-1衛(wèi)星遙感影像,通過監(jiān)測大潮高潮時刻和小潮低潮時刻海岸水陸邊界線,構建了潮間帶完整性系數(shù),以此為依據(jù)將海岸線劃分為自然海岸線、具有基本生態(tài)功能的人工海岸線、具有部分生態(tài)功能的人工海岸線、具有有限生態(tài)功能的人工海岸線、具有少量生態(tài)功能的人工海岸線和無生態(tài)功能的人工海岸線。在此基礎上,結合潮間帶完整性系數(shù)及其毗鄰海岸線長度,構建了海岸線生態(tài)化指數(shù),用以評價區(qū)域海岸線的生態(tài)化程度。營口市海岸線以無生態(tài)功能的人工海岸線、自然海岸線和具有少量生態(tài)功能的人工海岸線為主,分別占到海岸線總長度的45.74%、18.31%和15.53%。營口市總體海岸線生態(tài)化指數(shù)為0.29,其中西城區(qū)、老邊區(qū)、蓋州北、鲅魚圈區(qū)和蓋州南分別為0.55、0.17、0.40、0.10和0.55。
[Abstract]:The coastline is the boundary between the sea and the land, and it is also an important ecotone. This paper uses GF-1 satellite remote sensing image, by monitoring the tide high tide and neap rise time and coastal boundary line, build integrity coefficient of intertidal zone, on the basis of dividing the shoreline has the basic ecological functions of natural coastline, the artificial coastline, is part of the ecological function of artificial shoreline and artificial coastline, with limited ecological function with a small amount of ecological function of artificial coastline and ecological function of artificial coastline. On this basis, combining the intertidal integrity coefficient and the length of adjacent coastline, the coastal line Ecologicalization index is constructed to evaluate the degree of ecologicalization of the regional coastline. The coastline of Yingkou is mainly composed of artificial coastline without natural function, natural coastline and artificial coastline with a little ecological function, which accounts for 45.74%, 18.31% and 15.53% of the total length of coastline, respectively. The total coastline ecological index of Yingkou is 0.29, of which Xicheng District, old border area, Gaizhou north, Bayuquan area and Gaizhou south are 0.55, 0.17, 0.40, 0.10 and 0.55, respectively.

【正文快照】： 1引言海岸線是海洋與陸地的分界線,但受到潮汐、波浪、風暴潮等海洋水動力環(huán)境的影響,海岸線有進有退,時刻處于變化過程中[1—2]。這種海岸線的往復進退變化造就了海洋與陸地之間一種獨特的生態(tài)系統(tǒng)——潮間帶生態(tài)系統(tǒng)。潮間帶生態(tài)系統(tǒng)受海水漲落影響,漲潮為海,落潮為灘,具有，
