摘要
广西南临北部湾,是“一带一路”交汇的重要门户,拥有丰富的沿海港口资源、海洋生物资源、滨海旅游资源。对于海岸线位置变化和类型转换的遥感监测,可为海岸带的可持续发展和管理提供了宝贵的科学数据支持。本文采用1990–2020年5个时段的Landsat TM/OLI数据,对广西沿海地区进行海岸线提取研究。利用Arc GIS 10.2软件对海岸线的位置进行可视化解译,然后进一步将海岸线划分为人工和自然海岸线两个主要类别和生物质海岸线、砂质海岸线等6个二级类别。本数据集具有时间序列长、精度高、海岸线类型全面和聚焦2015年(可持续发展元年)前后海岸线变化趋势的特点,可用于海岸线时空分布特征和海陆格局演变的研究。
As an important gateway at the intersection of the'Belt and Road'initiative,Guangxi is situated along the Beibu Gulf to the south endowed with abundant coastal port infrastructure and marine biological resources.The remote sensing monitoring of the location change and type transformation along its coastline provides valuable scientific data support for the sustainable development and management of the coastal zone.The study uses Landsat TM/OLI data spanningz five time periods from 1990 to 2020 to delineate the coastline of Guangxi.We use ArcGIS 10.2 to visually interpret the coastline location,dividing the coastline into two primary types:artificial and natural,with six secondary categories.This dataset is characterized by long time series,high accuracy,comprehensive coastline types and a focus on coastline trends before and after 2015(the first year of sustainable development goals).The dataset can be applied to the study of spatial-temporal distribution characteristics of coastlines and the evolution of land-sea patterns.
