Representative nitrate type salt lakes are distributed in the Kumishi Basin in Xinjiang. The concentration of Sr2+ in the basin salt lakes is higher than that of other salt lakes in Xinjiang, but the migration and enrichment regularity of strontium ions in the salt lakes in the study area requires further investigation. In this paper, the research object is the content of strontium ions in nitrate salt lakes. The migration and enrichment regularity of strontium ions in nitrate typical salt lakes in the study area is discussed. The results are as follows:① Concentrations of Sr2+ tend to be enriched from northwest to southeast in the water bodies and sediments of the Kumishi Basin, consistent with the converging direction of the river. It is shown that Sr2+ of the salt lakes is mainly concentrated in the salt formation depression along with the river water (including groundwater); ② Regardless of water bodies or sediments, the variation trend of Sr2+ is consistent with that of K+ and Ca2+, NO3-, SO42- in chemical composition nitrate-type salt lakes. It is greatly affected by the material supply source of chemical components. Under the action of evaporation and concentration, the salinity of salt lake water bodies gradually increases, and the content of Sr2+ also increases. It is shown that the enrichment of Sr2+ is related to evaporation and concentration processes; ③ Main replenishment source of Sr2+ is the celestite deposit in the northwest and carbonate rocks (mainly Devonian limestone) and strontium-rich intrusive rocks in the northeast and northwest of nitrate-type salt lakes in the Kumishi Basin. Comprehensive analysis shows that migration and enrichment of strontium ions have the characteristics of multi-source and multi-directional replenishment.
