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

广西壮族自治区桂林市位于南方典型的喀斯特地貌区，地形复杂、森林类型多样。2015、2020、2025年桂林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2025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。

Guilin City, Guangxi Zhuang Autonomous Region, is located in a typical southern karst landform area, with complex terrain and diverse forest types. The 2-meter spatial resolution dataset of forest coverage and spatial distribution of major tree species in Guilin City for 2015, 2020 and 2025 was generated using GF-2 and SPOT-5 satellite imagery as data sources through machine learning classification methods. This dataset classifies forests into evergreen coniferous forests, coniferous and broad-leaved mixed forests, deciduous broad-leaved forests and evergreen broad-leaved forests. With a spatial resolution of 2 meters and temporal coverage of 2015, 2020 and 2025, this dataset can provide basic data support for regional forest resource monitoring, vegetation dynamic analysis and ecological protection assessment.
