摘要:

利用多时相卫星遥感图像复合的方法, 对烟台四个时相的TM影像进行处理并比较四个时相的海岸线长度和海湾面积的变化。结果表明, 自1986年到2004年近20年的时间里, 龙口湾、套子湾和芝罘湾三个海湾的海岸线总体趋势是增长的, 海湾面积则呈减少趋势。认为人为因素是烟台海岸线长度波动和海湾面积变化的主要原因并分析了这些变化对海岸环境和海岸生态系统的影响, 对本地区海岸带的可持续利用具有重要的指导意义。

The changing of typical bay coastline in Yantai in recent 20 years

Abstract:

Using the image fusion method for Multi-temporal Datasets, the paper studies Yantai's TM remote sensing images in four different dates and compares the differences of coast line length and the bay's area in those dates. The results shows the coastline length growing and bays' area decreasing in three bays, i.e. Longkou bay, Taozi bay, and Zhifu bays. Artificial factors are the main factors of the coastline's length fluctuating and area changing of the Yantai bay. These changes greatly influence the coast's environment and the coast eco-system. It is favorable to guide coastal zone sustainable utilization in Yantai.

Key words: remote sensing image bay coastline enclosing sea and cultivating Yantai
