Zusammenfassung:	Provided are a method for determining a total soluble salt (TSSC) in a saline soil, and a method for evaluating a soil type and a salinization degree of a saline soil. Based on a principle for measuring a refractive index, as well as a relationship that refractive index is directly proportional to a solution concentration, the TSSC is rapidly determined through measured refractive index and a linear relationship between the refractive index of a saline soil leachate and the TSSC. The TSSC is quickly determined by using a portable refractometer; and contents of chloride ions and sulfate ions are quickly determined by using a portable chloride ion electrode-sensing analyzer and a portable barium ion electrode-sensing analyzer, respectively. In this way, rapid determination of TSSC and evaluation of salinization degree in the saline soil are realized at a construction site.
