Current research mostly focuses on the response analysis of NDVI to climate factors and human factors, without considering the influence of nonlinear factors such as topography, soil characteristics, etc. Therefore, the monitoring of vegetation cover changes and the response of their influencing factors are of great significance in the study of terrestrial ecosystems. The Xinjiang NDVI spatial distribution pattern and its influencing factors dataset from 2000 to 2021 was obtained based on the GEE platform using MODIS remote sensing data and ERA5 Land Monthly Average dataset. The TIF data was processed into numerical data using ArcGIS software, and preprocessed using Python toolkit for cleaning and normalization, resulting in a numerical data set consisting of 14 fields and 2756 data points; Using Kriging interpolation method, the obtained data was spatially interpolated to obtain 13 spatial interpolation maps of influencing factors. This dataset can be used to construct a research model for the relationship between vegetation cover change and its influencing factors in Xinjiang, providing basic data for the impact of different influencing factors on NDVI changes, and further providing scientific basis for agricultural technology and environmental development management in the region. </p>",

By calculating the longitude and latitude information of each point, the 14 attributes are sequentially transformed into point files based on vegetation type vectors for value extraction to the point, so that each point can correspond to 14 fields. Then, removing outliers resulted in 2756 complete and valid data points. Then, using the Kriging interpolation method, perform spatial interpolation calculations on the influencing factors separately to obtain spatial interpolation distribution maps for each influencing factor. Finally, 2756 numerical data were normalized using the Python toolkit. </p>",
