Zhaoliang Song mainly studies the coupled silicon-carbon cycle in terrestrial ecosystems including grasslands, forests and croplands of China. He has proposed the innovative idea that silicon is coupled with terrestrial biogeochemical carbon cycle through plant-enhanced silicate weathering, phytolith turnover and secondary aluminosilicate accumulation and improved the theory of coupled terrestrial biogeochemical cycles of silicon and carbon. He has gained innovative achievements in the fields of phytolith carbon sink, carbon sink of silicate weathering and silicon cycle regulation. His achievements can provide scientific references for national and global carbon sink management practices. He has taken charge of many projects such as program of National Natural Science Foundation of China. He has been chosen as the key person to be trained as young talent scientist by several personnel training programs such as Distinguished-CORE, Distinguished Young and Middle-aged Academic Leaders of Higher Education Institutions of Zhejiang Province.
