Advances of the Research on the Biogeochemical Cycle of Silicon

Silicon,one of the most important life elements,plays an important role in both terrestrial and aquatic ecosystems.The biogeochemical cycle of silicon draws more and more attentions in recent years because of its close relation with the global carbon cycle and with the global climatic changes.In this paper,the research progresses of the biogeochemical cycle of silicon,including terrestrial and oceanic biogeochemical cycles and anthropogenic perturbations on the silicon cycle,are reviewed,some problems of the current research are pointed,and the crucial research field in the future is predicted.
