“一带一路”港口城市及其周边区域海岸线分类数据集

港口是"一带一路"基础设施建设的重点内容之一.基于2015年成像的Landsat 8 OLI卫星影像,根据"一带一路"沿线25个港口城市及其周边的海岸带生态环境状况,建立重要港口城市海岸线遥感目视解译的标志库,利用Arcgis10.0软件的矢量绘图功能,采用目视解译方法,对25个重要港口城市及其周边区域进行海岸线位置提取和类型划分工作;过程中,参照Google Earth影像绘制海岸线,以确保海岸线位置与类型都能够准确地勾绘或判读,最终得到"一带一路"沿岸重要港口城市海岸线分布和分类的矢量数据.25个港口城市分别是:上海,釜山,新加坡,雅加达,皎漂,曼谷,关丹,孟买,瓜达尔,加尔各答,吉大港,科伦坡,多哈,阿巴斯,吉达,迪拜,里斯本,圣彼得堡,吉布提,苏丹港,亚历山大,比雷埃夫斯,伊斯坦布尔,悉尼,达尔文.海岸线采用平均高潮线定义,分为自然岸线和人工岸线2大类,其中,人工岸线又分为丁坝突堤,港口码头,围垦中岸线,养殖岸线,盐田岸线,交通岸线,防潮堤岸线7种类型.研究表明,上海,新加坡,釜山等较为成熟和发达的港口城市及其周边区域的港口码头岸线以及与其配套的交通岸线等的分布较为普遍;皎漂,瓜达尔,关丹,吉布提等新兴或规模较小的港口城市及其周边区域仍然拥有非常丰富的自然岸线;其他的大多数港口城市及其周边区域则是明显有别于上述2类,即有相当规模的港口码头等人工岸线,又有大量的自然岸线.

Ports are one of the key components of infrastructure development under the "Belt and Road Initiative (BRI)". Based on Landsat 8 OLI satellite imagery acquired in 2015 and in accordance with the coastal ecological environment conditions of 25 port cities along the BRI and their surrounding areas, a remote sensing visual interpretation sign library for coastlines of important port cities was established. Using the vector drawing function of ArcGIS 10.0 software and the visual interpretation method, coastline position extraction and type classification were conducted for the 25 key port cities and their surrounding regions. During the process, Google Earth imagery was referenced for coastline delineation to ensure accurate plotting and interpretation of both coastline positions and types, ultimately obtaining vector data on the distribution and classification of coastlines of important port cities along the BRI. The 25 port cities are as follows: Shanghai, Busan, Singapore, Jakarta, Kyaukpyu, Bangkok, Kuantan, Mumbai, Gwadar, Kolkata, Chittagong, Colombo, Doha, Bandar Abbas, Jeddah, Dubai, Lisbon, Saint Petersburg, Djibouti, Port Sudan, Alexandria, Piraeus, Istanbul, Sydney, Darwin. Coastlines are defined by the mean high water line, and are divided into two major categories: natural coastlines and artificial coastlines. Artificial coastlines are further subdivided into seven types: groins and jetties, port wharves, reclamation coastlines, aquaculture coastlines, salt pan coastlines, transportation coastlines, and tide levee coastlines. Studies show that in relatively mature and developed port cities such as Shanghai, Singapore and Busan and their surrounding areas, port wharf coastlines and their supporting transportation coastlines are widely distributed; emerging or smaller-scale port cities such as Kyaukpyu, Gwadar, Kuantan and Djibouti and their surrounding areas still possess very abundant natural coastlines; most other port cities and their surrounding areas are distinctly different from the above two categories, boasting both considerable artificial coastlines such as port wharves and a large number of natural coastlines.
