| 摘 要： | 利用1990年、2000年和2010年三个时相的遥感影像,进行2000年前后两个十年的海岸线变迁情况对比分析。结果表明:2000年前的十年间,珠江口海岸线向海推进,导致面积共增加了16486.63ha,主要受人为因素影响,围海养殖是本时段海岸线变迁的主要因素;2000年后的十年间,珠江口海岸线继续向海推进,但推进速度降低,导致面积增加了9280.15ha,填海造地是这一时段海岸线变迁的主要因素。又根据珠江口的区域特征,以珠江入海八大口门为界,将整个研究区划分为九个岸段进行了详细分析。

| Abstract: | Using remote sensing images of 1990,2000 and 2010, the situation of shoreline changes during two decades before and after 2000 was compared and analyzed. The results showed that shoreline of the Pearl River Estuary had been advancing towards the sea in ten years before 2000, with the area of 16486. 63ha being increased, which was mainly caused by artificial factors, in this period the principal influence factor was sea aquaculture. Shoreline of the Pearl River Estuary continued to advance towards the sea in ten years after 2000 with the lower speed and increasing area of 9280.15ha, which was due to marine reclamation land. Based on the region characteristic of the Pearl River Estuary, we took the advantage of its eight outlets to divide the whole study area into nine coastal segments and analyzed them in detail. |
