“一带一路”海域生态环境遥感数据集

“一带一路”海域覆盖西太平洋、印度洋和东大西洋区域，水下地形复杂，包含水
深小于200m的陆架、200m至2000m的陆坡以及大于2000m的深海海盆。“21世纪海上丝
绸之路”途经的主要关键航行通道包括台湾海峡、吕宋海峡、马六甲海峡、卡里马塔海
峡、巽他海峡、望加锡海峡、托雷斯海峡、保克海峡、霍尔木兹海峡、曼德海峡、苏伊
士运河、莫桑比克海峡、好望角、土耳其海峡、直布罗陀海峡、英吉利海峡和斯卡格拉
克海峡等。根据地理位置和生态地理环境特征，选择“一带一路”海域内的12个海区和13个
近海海域，并利用2003～2014年的Aqua/MODIS结合HY-1A/B卫星COCTS月平均海洋遥
感产品，对海域生态环境进行遥感监测分析。海区包括日本海、中国东部海区、南海、
爪哇-班达海、孟加拉湾、阿拉伯海、波斯湾、红海、地中海、黑海、北海和波罗的海。

The maritime area of the Belt and Road Initiative (BRI) covers the western Pacific, Indian and eastern Atlantic Oceans, with complex underwater topography including continental shelves (water depth < 200 m), continental slopes (200 m ≤ water depth ≤ 2000 m), and abyssal basins (water depth > 2000 m). The main critical navigation channels along the 21st-Century Maritime Silk Road include the Taiwan Strait, Luzon Strait, Malacca Strait, Karimata Strait, Sunda Strait, Makassar Strait, Torres Strait, Palk Strait, Strait of Hormuz, Bab el-Mandeb, Suez Canal, Mozambique Channel, Cape of Good Hope, Turkish Straits, Strait of Gibraltar, English Channel, and Skagerrak Strait. Based on their geographical and eco-geographical characteristics, 12 sea areas and 13 offshore waters within the BRI maritime zone were selected for study. Remote sensing monitoring and analysis of the marine ecological environment were conducted using monthly average marine remote sensing products from Aqua/MODIS and the COCTS sensors onboard HY-1A/B satellites during 2003–2014. The 12 sea areas are the Sea of Japan, Eastern China Seas, South China Sea, Java-Banda Sea, Bay of Bengal, Arabian Sea, Persian Gulf, Red Sea, Mediterranean Sea, Black Sea, North Sea, and Baltic Sea.
