This data uses a large number of MODIS remote sensing images to analyze and calculate the surface vegetation coverage of the Qinghai Tibet Plateau from 2000 to 2018 based on the Google Earth engine platform. Vegetation index (NDVI) is an important index for monitoring ground vegetation. The 6th edition data of Terra moderate resolution imaging spectrometer (MODIS) vegetation index level 3 product (mod13q1) are generated every 16 days with a spatial resolution of 250 meters. The annual average NDVI index calculated based on GEE platform can reflect the long-term change trend of vegetation coverage from 2000 to 2018. Meanwhile, the multi-year average NDVI index from 2000 to 2018 reflects the spatial distribution of the Qinghai Tibet Plateau. The spatial-temporal change monitoring of vegetation index (NDVI) is an indispensable basic information and key parameter for environmental change research and sustainable development planning, which is helpful to understand the changes and impacts of some ecological factors (temperature, precipitation) under the background of climate change.

File naming and required software

"File name: NDVI data is stored in grid form (TIF). The file name is" xxxx\u mean.tif ", where XXXX represents the specific year.
Data reading method: the data is saved in TIF format, which can be opened by any software that can open TIF files. It is recommended to use ArcGIS, QGIS and other geographic information software. The index value is between -1 and 1: 0 means that there is basically no vegetation growth in the area; negative value means that the area is not covered by vegetation; Values between 0 and 1. The larger the number, the larger the coverage area of vegetation and the more vegetation,. "
