| 摘 要： | 在2001年应用“3S”技术与地面调查相结合的方法进行了广西红树林资源调查。以SPOT-HRV和Landsat 7 ETM 数据为信息源，采用1：1万地图形和GPS定位数据进行SPOT图象的几何精校正，并采用精校正后的SPOT图象对ETM 图象进行精校正。通过训练区对图象进行拉伸增强，然后采用锐化HIS变换的方法将SPOT图象与ETM 图象进行复合，经真彩色合成后得到的图象具有地物轮廓清晰、色彩丰富、层次分明的特点，红树林与滩涂、海域的区别十分明显，为红树林分布位置和边界的准确定位奠定了坚实的基础。

| Abstract: | An inventory for mangrove was carried out by combinin g remote sensing(RS),geographic information system(GIS),global positioning system( GPS) and field investigation together in 2001 in the coast of western Beibu Gulf of the Guangxi Zhuang Autonomous Region. This paper discussed the image process ing opproaches of SPOT-HRV image and Landsat 7 ETM+image.Furthermore,a series of image processing approaches aimed at mangrove mapping had been discussed,includ ing geometric correction, enhancement and fusion of images. The image acquired e njoyed the characteristics of clear outline, color enrichment,distinct gradation . Moreover, the tangible differences among mangrove,beach,and sea area appeared. All these lay a solid foundation for the accuration positioning of spatial dist ribution of mangrove. |
