| 摘 要： | 应用遥感技术,从海岸线长度和曲度两个方面分析辽东湾北部海岸线变化,研究区域海岸线变化规律和趋势.选用美国陆地卫星(Landsat)的MSS、TM、ETM+系列数据,法国SPOT/4-5系列数据和国产陆地卫星ZY-1 02C数据等多源遥感数据,通过人工目视解译和计算机信息自动提取结合的方法,监测了自1973~2012年辽东湾北部海岸线变化情况.研究表明,辽东湾北部海岸线长度和曲度均呈增加趋势,尤其是1997年以后,为快速增加时期,其中中段岸线增速最快,西段岸线次之,东段岸线居尾.人为因素是辽东湾北部海岸线变化主要驱动力.

| Abstract: | The paper analyzes the regional change rule and trend in the northern Liaodong Bay from the two aspects of length and curvature with RS technology. Using multi-source RS data such as MSS/TM/ETM+ series data of US Landsat, French SPOT/4-5 series data and China Resources Satellite ZY-1 02C data, combining with the methods of artificial visual interpretation and computer automatic information extraction, the coastal changes in northern Liaodong Bay during 1973-2012 are monitored. The study shows that the length and curvature of coastline in northern Liaodong Bay are both increasing, especially after 1997 when they increase rapidly. The middle section of the coastline has the fastest increasing speed, followed by the west section and the east section. The main driving force for the change is human factors. |
