Agricultural land sensitivity classification map of Qinghai Tibet Plateau (2015)
In this study, the cultivated land, forest land and grassland of the Qinghai Tibet Plateau in 2015 were taken as the evaluation objects to analyze the terrain, climate, soil and vegetation factors (terrain: altitude, slope; climate: sunshine hours, ≥ 0 ℃ accumulated temperature, annual average precipitation; soil: soil texture, soil erosion intensity, soil layer thickness; vegetation: vegetation type, NDVI) that have significant impact on land sensitivity and establish agriculture Land sensitivity evaluation index system. Using AHP method to determine the weight of evaluation factors, according to the ArcGIS Jerks classification method to get the sensitivity level of cultivated land, forest land and grassland, output 250m resolution of the Qinghai Tibet Plateau agricultural land sensitivity map, and verify the results.
File name: the data is stored in TIF file format, and the file name is:
cultivated land sensitivity.tif
forest land sensitivity.tif
grassland sensitivity.tif。
Data reading method: ArcGIS can be used to open the data, including the sensitivity evaluation level of cultivated land, grassland and forest land in the Qinghai Tibet Plateau in 2015. 1 represents insensitivity, 2 represents low sensitivity, 3 represents medium sensitivity, and 4 represents high sensitivity. Coordinate system projection: Albers ﹣ conic ﹣ equal ﹣ area
