With the advances of theory and analysis technique of Sr isotopes, the application of stable Sr isotope as tracers of biogeochemical processes on both the catchment and global scales has increased considerably in recent years, and it continues to provide new insight into many different research problems. This paper reviews the basic principle, main research content and recent progresses of using Sr isotopes to trace nutrient element circulation and hydrochemical evolution in ecosystems. The authors emphasize the application of strontium isotopes to study mineral weathering rates, identify resources of nutrient elements, calculate circulation fluxes of the elements and trace hydrochemical evolution mechanism of groundwater. At the same time, the authors point out the complexity and problems needing attention
when Sr isotope are used as tracers of biogeochemical processes. At last, the potential application of strontium isotope to trace biogeochemical processes is discussed.
