<p>The vegetation coverage data set of national key prevention areas in the northern foot of Yinshan Mountain in 2022 includes the vegetation coverage statistical tables of Darhan maoming'an United banner, Wulate Middle Banner, Wulate rear banner, Siziwang Banner, Sunite Left Banner and Sunite Right Banner in Inner Mongolia Autonomous Region in 2022, which are processed based on satellite remote sensing image with spatial resolution of 2m, and saved in xlsx format, The data are named in the form of "key management area + year + vegetation coverage statistical table", such as“ ×× Key governance areas ×× Statistical table of annual vegetation coverage. The vegetation coverage is divided into five levels: high coverage, medium high coverage, medium coverage, medium low coverage and low coverage.</p>
<p>The data sources are ZY-3 and Gao FEN-1 satellite images, which are mainly obtained from the information center of the Ministry of water resources.</p>
<p>Based on the method of remote sensing estimation, the normalized vegetation index (NDVI) is used to estimate the vegetation coverage by using the pixel dichotomy model. The method is to first calculate the NDVI of each pixel using the near infrared band and red band data of multispectral images, and then use the model to calculate the vegetation coverage of the whole region. Then the land use type data from remote sensing interpretation and the vegetation coverage data from remote sensing estimation are superimposed to obtain the vegetation coverage information of each pixel. Finally, according to the classification rules, the vegetation coverage was classified, and the statistical table of forest and grass vegetation coverage was obtained.</p>
