A dataset of coastal zone factors in Guangxi Beibu Gulf,China,during 1990-2022
The Beibu Gulf in Guangxi serves as an important gateway for the Belt and Road Initiative,boasting abundant coastal port resources,marine biological resources,and coastal tourism attractions.However,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,and expanding the time range and scale of coast zone factor extraction,is of great significance for coastal zone environmental monitoring and assessment.Using a semi-automatic extraction method,this study constructs three sets of 6-phase multi-factor datasets of the coastal zone in Guangxi Province,China,spanning from 1990 to 2022,including the information on mangroves,aquaculture ponds,and coastlines,and covering the years 1990,2000,2010,2015,2020,and 2022.The overall accuracy for mangroves is approximately 90%,exceeding 90%for aquaculture ponds,with the coastline displacement less than 20 m.Featuring a long time series,high precision,and multiple factors,this dataset can be used for studying the spatiotemporal distribution characteristics of the coastal zone and the evolution of marine-land patterns.
