摘　　要：运用遥感与地理信息系统技术提取海岸线、海岸滩涂面积、海岸湿地景观格局以及沿海6市的上地类型变化信息,从自然、人文两方面选取指标构建辽宁省海岸带环境脆弱性评价指标体系,采用投影寻踪与动态层次分析模型,从时间和空间两个角度对辽宁省海岸带环境脆弱性进行评价。结果表明:1990—2008年辽宁省海岸带中的大连市海岸带环境脆弱性呈波动增强趋势,海岸带其他地区的环境脆弱性呈波动减弱趋势;空间上各地区海岸带环境脆弱性差异显著,其中,大连市海岸带环境脆弱性投影值最大,海岸带环境最优,而盘锦市的投影值最小,海岸带环境承受最大压力。This paper intends to provide a case study of the Liaoning coastal zone, which is in the most economically developed region of Liaoning Province. As is seen, the coastal areas of a country used to be the most important habitats for human societies, but now they are confronting more and more environmental challenges, such as the sea-level rising-up, biodiversity declining, fishery resources degeneration and so on. All this has made urgently necessary the sea-water environmental vulnerability assessment and the protection of marine animals and plants. For the purpose of the marine environmental protection, first of all, we think it necessary to define the coastal areas vulnerability, and its corresponding attributes, such as objectivity, sensitivity and limited recovering capacity. Next, we have listed thirty-one factors influencing the sustainable development of our marine environment and the forming of the assessment indicating system, which are based on the four aspects of natural factors and human-activity affecting factors, including： （1） the land environmental indictor, （2） the sea environmental indictor, （3） the social indictor, and （4） the economic indictor. The information of such indictors can be extracted in the form of the geographical shape and length of the coastline, the coastal region area, sea-beach wetland landscape patterns, land-covering change information of the six coastal cities in Liaoning by applying the RS（remote sensing） and GIS（geographic information system） technology. Secondly, the methods of projection pursuit and dynamic analytic hierarchy process have been adopted to evaluate the vulnerability of Liaoning＇s coastal areas from the spatial and temporal aspects. The results of our investigation show that： （1） In temporal aspects, Dalian city has been revealing an ever increasing tendency of environmental vulnerability sometimes with fluctuations from 1990 to 2008, though somewhat improved and even tends to be better, while the other five cities in the
