摘　　要：在保护海洋生态环境的原则下,实现陆海统筹发展是生态文明建设的重要内容之一。海岸线是研究海陆关系的重要载体,本文选取深圳市大陆海岸线为研究对象,通过对Landsat TM/OLI遥感影像的处理与提取,获得深圳市1988、1993、1998、2003、2008、2013、2018、2021年共8期海岸线数据。基于岸线提取结果对8期深圳岸线进行量化处理,从长度、形态、类型、开发4个角度分析深圳市大陆海岸线演变格局。分析结果表明:研究时段内,深圳大陆海岸线在长度与形态上总体趋势为不断变长、变曲折;在岸线类型与开发强度上,自然岸线不断减少,人工岸线逐年增加,城镇建设岸线逐渐成为深圳市海岸线的主体。东西海岸由于地理环境要素差异而空间分异突显,西海岸的人工化指数与开发强度要明显高于东海岸。Under the principle of protecting the marine ecological environment,the coordinated development of land and sea is one of the important contents of ecological civilization construction,and the coastline has become an important target for studying the relationship between land and sea.The coastline in Shenzhen was taken as the research object.By processing and extraction of Landsat TM/OLI remote sensing images,shorelines of Shenzhen in 1988,1993,1998,2003,2008,2013,2018,and 2021 were obtained.Based on the results of shoreline extraction,the Shenzhen shorelines in the past 8 periods were quantified,and the evolution pattern of Shenzhen shorelines were analyzed in terms of length,form,type,and development intensity.Results show that since 1988,the length and form of the coastline have been constantly lengthening and winding.The types and development intensity of the natural shoreline has been decreasing,while the artificial shoreline has been increasing year by year.The urban construction shoreline is gradually becoming the main body of Shenzhen shoreline.The spatial differentiation between the eastern and western coastlines is obvious due to the difference of geographical environmental factors.The artificial index and development intensity of the western coastline are significantly higher than eastern one.
