三江源300米分辨率ESA土地覆盖数据集（1992-2015）

该数据集包含了从1992到2015年的逐年黄河源、长江源、澜沧江三个源区的土地覆盖数据集。共包括了22种基于UN Land Cover Classification System的土地覆盖类型。集成了NOAA AVHRR, SPOT, ENVISAT, PROBA-V等植被分类产品。在中国区，（1）首先结合我国1：10万植被分类（2007）进行了质量订正和控制；（2）我国植被分类中侧重与气候区的结合，在订正CCI-LC时与我国气候区划相结合，与我国气候区划类型对应的植被类型相结合，全面订正了数据标签。

This dataset provides annual land cover data for the three source regions: the Yellow River source, Yangtze River source, and Lancang River source, spanning from 1992 to 2015. It includes a total of 22 land cover types compliant with the UN Land Cover Classification System, and integrates vegetation classification products including NOAA AVHRR, SPOT, ENVISAT, and PROBA-V.
For the Chinese regional portion:
1. Quality correction and control were first conducted using China's 1:100,000-scale vegetation classification data (2007);
2. China's vegetation classification prioritizes integration with climatic zones. During the revision of the CCI-LC dataset, we aligned the data with China's climatic regionalization and the vegetation types corresponding to each climatic regionalization category in China, and comprehensively revised all data labels.
