Soil Salinity - Non-watertable

Non-watertable salinity (or dry saline land) is where soil contains elevated levels of soluble salts that are not associated with a watertable. Mapping shows the degree of non-watertable salinity, based on the most saline part of the map unit (provided it occupies at least 30%), while detailed proportion data are supplied for calculating respective areas of each non-watertable salinity class (spatial data statistics).

无地下水位盐渍化（Non-watertable salinity，又称干盐渍地）指土壤中可溶性盐含量升高且与地下水位无关的区域。本数据集的盐渍化程度制图基于制图单元内盐渍化最严重的部分（该部分占比需至少达到30%），同时附带详细占比数据，用于计算各类无地下水位盐渍化等级的对应面积（空间数据统计）。
