摘要:
本文基于遥感技术与GIS技术，提取了2000年、2010年的山东省海岸线，并对十年间山东省海岸线变化进行了系统分析。结果表明：十多年来，受人为开发与海陆作用的综合影响，山东省的海岸线总长度呈增加趋势，主要以人工岸线的增加为主，如建设围堤和码头岸线的迅速增加。随着人工岸线的增加，自然岸线相应减少，主要以砂砾质岸线和淤泥质岸线的减少为主。人类工程建设是山东省海岸线变化的最主要原因。与人类活动相比，自然变化如河口淤积与侵蚀对山东省海岸线影响比较小。
In this paper, based on the technology of GIS and RS, coastlines in the year of 2000 and 2010 of Shandong were interpreted from remote sensing images. The analysis of spatial and temporal changes of coastlines shows that: Shandong coastline changes are mainly affected by human factors. The total length of the coastline is increasing in the past ten years, which is evidently in the changes of artificial coastline. The temporal and spatial variation is mainly reflected in industrial land use, town and port construction. With the increase of artificial coastline, natural coastline reduced. Compared with human activities, the impacts of natural changes such as river estuary deposition and erosion on the coastline of Shandong province are relatively small.
