中文摘要：

本文选取大连大孤山地区作为研究对象，基于1993年、2000年、2007年和2014年四个时期的遥感影像，通过GIS分析岸线分类变化和演变速率变化，并就港口对岸线的影响做了探讨。研究显示，大孤山地区岸线是港口主导下的演变模式，整体呈现向海侧拓展趋势，自然岸线比例下降，港口岸线比例增长较快，未来将面临岸线资源、城市功能和生态保护等多方面的压力。

英文摘要：

With the aggravation of human activities such as port construction, great changes involving coastline utilization and its spatial location are taking place, and more attention is paid to the rational utilization of coastline resources. Therefore, to study the effect of port development on the spatial and temporal changes of the coastline can provide a reference for the exploitation of offshore area. Four remote sensing images of Dalian Dagushan area taken in 1993, 2000, 2007 and 2014 are selected to carry out GIS analysis on the coastline variations involving classification and evolution rate as well as further discussion on how a port affects coastline. Based on the research results, the change of Dagushan coastline is defined as port-dominated evolution pattern, the integral coastline expands seaward, the proportion of natural coast decreases while that of port shoreline increases significantly. Dagushan area will face more challenges related to coastline resources, urban functions and ecological protection in the future.
