在地球上，红树林在海岸保护方面发挥着重要作用，既是苗圃，也是碳汇。然而，由于人类和环境的各种影响，红树林的覆盖率在全球范围内正在下降。红海是红树林分布范围的最北部地区。人们对这一北方界限红树林覆盖的表面或红海红树林所经历的变化知之甚少。我们试图通过使用多时相陆地卫星数据（1972年，2000年和2013年）来研究红海红树林覆盖范围的变化。有趣的是，我们的研究结果表明，红海的红树林没有减少，而是略有增加。红树林覆盖的区域沿非洲海岸约有69公里（2）沿着，沿阿拉伯半岛海岸约有51公里（2）沿着。从1972年到2013年，红树林覆盖面积增加了约0.29% y（-1）。我们的结论是，红海红树林所表现出的趋势偏离了全球红树林的普遍下降。沿着红海，红树林在1972年至2013年的41年间扩张了12%。红海红树林的损失主要是由于沿海开发造成的，已通过造林项目得到补偿。(C)2015爱思唯尔有限公司版权所有。
Across the Earth, mangroves play an important role in coastal protection, both as nurseries and carbon sinks. However, due to various human and environmental impacts, the coverage of mangroves is declining on a global scale. The Red Sea is in the northern-most area of the distribution range of mangroves. Little is known about the surface covered by mangroves at this northern limit or about the changes experienced by Red Sea mangroves. We sought to study changes in the coverage of Red Sea mangroves by using multi-temporal Landsat data (1972, 2000 and 2013). Interestingly, our results show that there has been no decline in mangrove stands in the Red Sea but rather a slight increase. The area covered by mangroves is about 69 Km(2) along the African shore and 51 Km(2) along the Arabian Peninsula shore. From 1972 to 2013, the area covered by mangroves increased by about 0.29% y(-1). We conclude that the trend exhibited by Red Sea mangroves departs from the general global decline of mangroves. Along the Red Sea, mangroves expanded by 12% over the 41 years from 1972 to 2013. Losses to Red Sea mangroves, mostly due to coastal development, have been compensated by afforestation projects.
