【摘要】：基于遙感和地理信息系統(tǒng)的方法與技術(shù),通過對1990、2000、2009和2013年4個時相的Landsat衛(wèi)星遙感數(shù)據(jù)和2013年資源衛(wèi)星數(shù)據(jù)分析,獲得了近20多年來威海海岸線演變的信息。研究表明,威海市圍填海活動頻繁,岸線變化顯著,人工岸線所占比例由1990年的50.7%上升到2013年的57.8%;海岸線變化呈現(xiàn)顯著區(qū)域特征,變化較劇烈的區(qū)域集中在環(huán)翠區(qū)雙島港、楊家灣,及文登五壘島灣;岸線變遷的主要驅(qū)動力表現(xiàn)為早期的灘涂圍墾養(yǎng)殖及中后期的碼頭建設(shè)和海洋開發(fā)利用。
[Abstract]:Based on the methods and techniques of remote sensing and geographic information system (GIS), through the analysis of Landsat satellite remote sensing data in 1990 / 2000 and 2013 and resource satellite data in 2013, information on the evolution of Weihai coastline in recent 20 years has been obtained. The study shows that Weihai City has frequent reclamations and obvious changes in the shoreline, the proportion of artificial shoreline has increased from 50.7% in 1990 to 57.8% in 2013, the coastline changes show significant regional characteristics, and the areas with more drastic changes are concentrated in the Shuangdao Port in the Huankui District. Yangjiawan and Wendeng Wubiedao Bay, the main driving forces of shoreline change are the early tidal flat reclamation and breeding, the terminal construction and marine exploitation and utilization in the middle and late stages.
