According to the researches during the last several decades about fine roots system in China and abroad,several main realms on fine roots were concluded here,such as fine root decompose,fine root longevity,fine root turnover and fine root senescence.

Aims Fine root turnover is a major pathway for carbon and nutrient cycling in forest ecosystems, but our understanding of fine root turnover is limited, because fine root dynamic processes associated with soil resource availability and climate factors are poorly understood.

Fine root longevity is a key parameter in estimating fine root turnover, which determines the velocities of C- and nutrients consuming and cycling.
