大湄公河次区域30m年最大植被盖度数据集

大湄公河次区域涵盖多种气候类型，兼具多种地理特征，植被覆盖率高，拥有丰富的森林资源，生态环境状况多样。但随着城市化扩张，地表利用类型改变，植被盖度下降。基于30m空间分辨率的中国环境一号卫星A星和B星CCD（HJ-1A/CCD1、HJ-1A/CCD2、HJ-1B/CCD2、HJ-1B/CCD2）提取的植被盖度产品监测2013年6月~2014年5月期间大湄公河次区域植被盖度空间分布状况以及季节分布差异，对阐述中国-东盟的典型生态环境问题具有重大意义。本数据集压缩后的数据量为2.04GB，共享方式为完全开放共享。

The Greater Mekong Subregion (GMS) features diverse climate types and varied geographical characteristics, with high vegetation coverage, abundant forest resources and a wide range of ecological environments. However, with the expansion of urbanization, land use types have changed, leading to a decline in vegetation coverage. The vegetation coverage product, extracted from the Charge-Coupled Device (CCD) data of China's HJ-1A and HJ-1B satellites with a 30 m spatial resolution (including HJ-1A/CCD1, HJ-1A/CCD2, HJ-1B/CCD2, HJ-1B/CCD2), was used to monitor the spatial distribution and seasonal differences of vegetation coverage in the GMS from June 2013 to May 2014. This dataset is of great significance for elucidating typical eco-environmental issues between China and the Association of Southeast Asian Nations (ASEAN). The compressed size of this dataset is 2.04 GB, and it is shared under fully open access terms.
