In some parts of Qinghai Province, the saline soil having sodium sulfate content of less than 1% will also has salt-inflation, and dissolved subsidence does not occur in the ultra-chloro-saline soil. The geological environment tends to play a decisive role. The relevant specifications given in sodium sulfate content of more than 1% are not fulfilled before considering the expansion of salt. The ultra-chlorosaline soil in the hinterland of the Qaidam Basin does not lead to produce anti-solvent trap due to insoluble salts and high content of soluble salts. These perceptions and viewpoints are quite different from the existing theories and norms.
