1990-2015年海上丝绸之路沿线30mLandsatTM/OLI近岸水产养殖区分布范围及其变化数据集

近海水产养殖业是“海上丝绸之路”沿线国民经济的重要组成部分，为经济发展和粮食安全做出了巨大贡献，但同时也对周边生态环境有重要影响。基于Landsat系列影像结合Google Earth高空间分辨率影像，建立水产养殖区解译标志库，结合近海水产养殖区的影像光谱特征与空间分布特征，完成水产养殖区空间分布制图。以1990和2015年水产养殖区空间分布数据为基础，开展变化检测，生产了1990-2015年东盟十国近岸水产养殖时空变化数据并制图。

Coastal aquaculture is an important component of the national economies along the Maritime Silk Road, having made significant contributions to economic development and food security while exerting substantial impacts on the surrounding ecological environment. Based on Landsat series imagery and high-spatial-resolution imagery from Google Earth, a library of interpretation signs for aquaculture areas was established. Combined with the spectral features of remote sensing imagery and spatial distribution characteristics of coastal aquaculture areas, spatial distribution mapping of aquaculture areas was completed. Using the spatial distribution data of aquaculture areas in 1990 and 2015, change detection was performed, and the spatiotemporal change dataset of coastal aquaculture in ASEAN-10 from 1990 to 2015 was produced and mapped.
