摘　　要：利用多源数据,将TM和SPOT5全色波段数据融合,对防护林树种进行分类,结果表明,漳浦县沿海防护林主要由木麻黄、湿地松、相思树和马尾松4类组成。并利用多时相遥感数据对漳浦县的1998～2001年进行动态监测,结果表明在这短短的几年中,其防护林面积有了一定的减少。Zhangpu county lies in coastal of Zhangzhou,Fujian province,which has a coastal line of 218 km.Therefore the construction of littoral shelter forest is important for the environment and economy.The article used multi-source data and TM and SPOT-5 images were merged to classify the trees species of the littoral shelter forest.The result reveals that the littoral shelter forest of Zhangpu county is mainly composed of four species:Casuarina equisetifolia,Pinus elliottii,Acacia confusn,and Pinus massonianai.And multi-temporal imagery was used to dynamic monitor the littoral shelter forest.The final results indicated that littoral shelter forest has been significantly reduced during the study years.
