| Abstract: | There was a large area of mangroves distributed in the western Xiamen Harbour, but it has been damaged a lot in recent decades. In order to manage and monitor mangrove re sources, some measures are needed to be taken. Satellite remote sensing technology provides a macroscopic, rapid and precise method for mangrove resources monitoring and plotting,and it is cheaper and less time-consuming than traditional artificial investigation methods.In this program, the Landsat TM image-CCT digital image magnetic tape has been used as an information source. First, with computer the image pre-proccessing is carried out,such as image geometric rectification, pseudo-color composition, linear scale image enhance ment and histogram linearization. Secondly, supervised classification is used to class the mangroves according to training samples,and the mangrove area is calculated by integrating the pixels. Finally, we made a 1: 50 000 pseudo-color composed imagery map of mangrove distribution. The mangrove area calculated by computer is 73. 89 hectares, comparing to the 75. 40 hectares by grid statistic method, the accuracy bying 98%. In all, this research work gives a convenient method and model for mangrove resources dynamic monitoring and remote sensing survey and mapping. |
