摘　　要：作者以粤港澳大湾区为研究区,基于面向对象方法完成空间场景分类数据;耦合三维生态足迹方法,建立基于空间场景的海岸带生态承载力数据集(1990–2019)。运用混淆矩阵计算1990、2000、2010和2019年空间场景分类结果的总体精度分别达到85.10%、82.72%、80.19%和80.65%。该数据集内容包括研究区以下数据:(1)4个历史时期(1990、2000、2010、2019年)海岸线、海岸带与海域空间场景空间分布数据;(2)每10年空间场景陆海变迁数据;(3)1990–2019年海岸带与海域生态承载力与生态足迹变化数据。数据集存储为.shp、.tif和.xlsx格式,共58个数据文件,数据量为2.75 GB(压缩为1个文件,8.97 MB)。Taking Guangdong,Hong Kong and Macao Greater Bay Area as the study area,the authors completed the spatial scene classification data based on the object-oriented method;coupled with the three-dimensional ecological footprint method and established the spatial scene-based ecological carrying capacity dataset of the coastal zone(1990—2019).The overall accuracies of the spatial scene classification results for 1990,2000,2010 and 2019 were calculated using the confusion matrix to reach 85.10%,82.72%,80.19%and 80.65%,respectively.The content of this dataset includes the following data in the study area:(1)spatial distribution data of the spatial scenes of coastline,coastal zone and sea area in four historical periods(1990,2000,2010 and 2019);(2)data of land-sea variation of spatial scenes in every 10 years;and(3)data of ecological carrying capacity and ecological footprint change of coastal zone and sea area from 1990 to 2019.The dataset is archived in.shp,.tif and.xlsx formats,with a total of 58 files and a data size of 2.75 GB(compressed into 1 file,8.97 MB).
