2015、2020、2025年郴州市城区森林覆盖及主要树种空间分布数据集 (2m)

湖南省郴州市位于我国南岭山地丘陵区，地形复杂、森林类型多样。2015、2020、2025年郴州市森林覆盖度及主要树种空间分布数据集（2m）以GF-2与SPOT-5卫星影像为数据源，采用机器学习分类方法生成。数据集将森林分为常绿针叶林、针阔混交林、落叶阔叶林和常绿阔叶林。数据空间分辨率为2米，时间覆盖2015年、2020年与2024年，可为区域森林资源监测、植被动态分析及生态保护评估提供基础数据支撑。

Chenzhou City, Hunan Province is located in the Nanling Mountainous and Hilly Region of China, featuring complex terrain and diverse forest types. The spatial distribution dataset of forest coverage and major tree species in Chenzhou City (2 m resolution) for the years 2015, 2020 and 2025 was generated using GF-2 and SPOT-5 satellite images as data sources via machine learning classification methods. The dataset classifies forests into four categories: evergreen coniferous forest, coniferous and broad-leaved mixed forest, deciduous broad-leaved forest, and evergreen broad-leaved forest. With a spatial resolution of 2 meters, the dataset covers the years 2015, 2020 and 2024, and provides fundamental data support for regional forest resource monitoring, vegetation dynamics analysis and ecological protection assessment.
