中国盐田空间分布数据集（2013）

本数据集包括2013年全国盐田分布数据。这些数据通过Landsat卫星遥感影像人工解译提取盐湖图斑，矢量化处理后形成。主要包含盐田名称（YT）、盐性编号(YXBH)、所在省份(SF)等信息。数据集共有39条记录，56.00KB。数据集文件名及数据表标志名对应如下：盐田名称 YT、盐性编号 YXBH、所在省份 SF。采用WGS-84坐标系为空间基准，精度为1:30万，粒度以县级行政区为最小单元，以省级行政区为最大单元。

This dataset contains the 2013 national salt pan distribution data. This data was extracted via manual interpretation of Landsat satellite remote sensing imagery to obtain salt lake patches, then finalized through vectorization processing. It primarily includes attributes such as salt pan name (YT), salinity serial number (YXBH), and hosting province (SF). The dataset consists of 39 records in total, with a file size of 56.00 KB. The correspondence between dataset file names and data table field names is as follows: Salt Pan Name: YT, Salinity Serial Number: YXBH, Hosting Province: SF. It uses the WGS-84 coordinate system as its spatial reference, with a mapping precision of 1:300,000. The spatial granularity takes county-level administrative regions as the smallest unit and provincial-level administrative regions as the largest unit.
