摘      要：Fine roots（≤2mm in diameter） play important roles in carbon balance and nutrient recycling in forest *** the development of the study on global carbon cycle,fine roots have attracted considerable attention as the main source of soil carbon in forest *** the basis of synthetic analysis of research reports in domestic and foreign literatures,we summarized and elaborated the major abiotic and biotic factors that control fine root production and *** environmental factors included soil nutrient,soil temperature,soil moisture and the CO2 *** organisms,fine root morphology and forest stand characteristics were discussed as biotic factors in this ***,we defined the problems arising in root system research and prospected the future research direction.
