摘    要:利用1990年的Landsat-5TM、2000年的Landsat-7ETM+和2008年的CBERS-02BCCD 3期遥感影像对广东省近18a来的红树林湿地资源进行监测,并对其时空变化情况进行分析。结果表明:广东省红树林呈现不断增加的趋势,1990年、2000年和2008年的面积分别为7 733.2,8 722.0和9 593.3hm2;红树林由沿岸分散分布趋于集中分布;天然林减少,人工林增加。

关 键 词:广东省  红树林  变化  遥感监测

Abstract:Mangrove forests are distributed along the coastlines in tropical and sub-tropical area.Mangrove wetlands are important habitats for ecological species and have many ecological functions such as bank protection,pollution elimination and conservation of biological diversity etc.In China’s southern coast and the mouth of the Gulf,there exist a lot of mangroves.Based on the image data from 1990 Landsat-5 TM,2000 Landsat-7 ETM+ and 2008 CBERS-02B CCD,the mangrove wetland resources in recent 18 years in Guangdong Province were monitored,and their temporal and spatial variations were analyzed.The results indicate that the area of the mangrove wetland presents a continuous increase trend,with the area of 7 733.2 hm2 in 1990,8 722.0 hm2 in 2000,9 593.3 hm2 in 2008;the decentralized distribution tends to be centralized;and the natural mangroves decreases while the artificial ones increase.The results of this study can provide data of reference for the protection and management of the mangrove wetland for relevant authorities of Guangdong Province.
Keywords:Guangdong Province  mangrove forest  change  remote sensing monitoring
