2024-06-27 A dataset of coastal zone factor changes in Guangxi Beibu Gulf, China, during 1990-2022 doi:10.57760/sciencedb.j00001.01125 en The Beibu Gulf in Guangxi is an important gateway for the Belt and Road Initiative, with abundant coastal port resources, marine biological resources, and coastal tourism resources. Economic activities in the ocean may have a negative impact on the living environment of marine plants and animals. Environmental changes reflect the extent of human activities' utilization and destruction of coastal resources, as well as changes in marine ecology. Therefore, providing data support for the sustainable development of the coastal zone, expanding the time range and scale of coastline extraction, is of great significance for coastal zone environmental monitoring and assessment. This study used a semi-automatic extraction method to construct three sets of 6-phase multi-factor change datasets of the coastal zone in Guangxi Province, China, from 1990 to 2022, including mangroves, aquaculture ponds, and coastlines, covering the years 1990, 2000, 2010, 2015, 2020, and 2022. This dataset has the characteristics of long time series, high precision, and multiple factors, which can be used for the study of the spatiotemporal distribution characteristics of the coastal zone and the evolution of marine-land patterns.
