泉州湾海岸线变迁遥感监测研究

The Remote Sensing Dynamic Monitoring of QuanZhou Bay Coastline Change

基于Landsat MSS/TM、SPOT5、World View-1卫星数据,运用计算机技术对卫星遥感数据进行分析处理,经几何纠正、配准、彩色合成、融合图像处理等方法,分析研究泉州湾海岸岸相特征,通过提取相应时期海岸线,研究泉州湾海岸23年（1988~2011年）的变化特征。研究表明,泉州湾海岸线变迁主要受人为活动影响,海岸线变迁最大的是泥质海岸带,砂质和基岩等海岸带的变化较小,集中于湾内西北岸,南北两岸则相对稳定。

Using computer technology to analyze and process the data of satellite remote sensing imaging of Landsat MSS / TM、SPOT5、World View-1、2 and other satellite data,including geometric correction,registration,color image processing method,this paper studies the Gulf of Quanzhou coast 20years（ 1988 —2011） change characteristic,by extracting the coastline and analyzing the characteristics of shore facies. The results showed that,the Quanzhou Bay coastline changes mainly affected by human activities,which is the largest of the muddy coast,small change of sand and rock coast,where is concentrated in the west of North Bay,north shore is relatively stable.
