Silicon (Si) is an essential nutrient for many marine organisms, such as diatoms, and plays an important role in marine ecosystem as well as carbon cycles. Under the background of global warming, the runoff of meltwater increases rapidly with the accelerated melting of glaciers. Meanwhile, the silicate weathering gradually increases, leading to the release of a large number of Si elements with meltwater and into the downstream, which may affect the primary productivity of marine and lake ecosystems, the global carbon cycle and climate change. Recently, the research of Si related to glacier retreat has become one of the hot scientific issues globally in the background of global climate warming. In addition, we summarized the latest research achievements of Si concentrations and its δ30Si in glaciers, ice sheets and iceberg sources, analyzed the spatial variation characteristics of the Si concentration, found that the Si concentration of glacial runoff is affected by the sampling method, runoff, bedrock characteristics and other factors. Based on summarizing the existing problems in this field, it’s necessary to strengthen the field monitoring, and comprehensively utilize various isotopes method to clarify the transformation process of Si in glacial runoff in the future. Then, it is also important to assess Si fluxes into the downstream ecosystem because of melting glaciers, and thus provide scientific guidance for the significance of glacier Si assessment.

Key words: silicon (Si), silicon stable isotope ratio (δ30Si), glaciers
