This data set includes the distribution data of national salt fields in 2013. These data are formed after the salt lake map spots are extracted by manual interpretation of Landsat satellite remote sensing images and vectorized. It mainly includes salt field name (YT), salt number (yxbh), province (SF) and other information. There are 39 records in the dataset, 56.00kb.
