基于1987–2017 年Landsat数据的海南岛红树林变化数据集

Landsat data of mangrove forest changes in Hainan Island during 1987–2017

红树林分布在热带–亚热带地区的海岸带湿地,具有重要的生态及生态经济服务价值。本研究利用1987年、1993年、1998年、2003年、2007年、2013年、2017年共计7期Landsat TM/OLI数据,采用支持向量机分类方法,并结合野外调查资料,获取了1987–2017年海南岛红树林变化数据集。本数据集可用于红树林时空变化分析,以及红树林湿地生态系统恢复、保护和管理的决策支持,为海南省生态环境监管提供基础数据支持。

Distributed in the coastal wetlands of tropical and subtropical regions throughout the world,mangrove forests provide important ecological and eco-economical services such as coastal erosion prevention,water purification,nursery habitats for marine fish and shrimp breeding,provision of building materials and medicinal ingredients,and tourist attraction.A dataset of mangrove forests changes from 1987 to 2017 in Hainan Island was developed using Landsat TM/OLI images obtained in 1987,1993,1998,2003,2007,2013 and 2017.This dataset was compiled through a support vector machine(SVM)classification method based on ground survey data.It can be used to understand the status and dynamics of mangrove forests,and to support decision-making concerning the restoration,protection and management of mangrove wetland ecosystem.Further,the dataset provides basic data for ecological environment monitoring in Hainan Province.
