英文摘要：

The soil moisture and soil nutrient can directly influence dynamic,turnover and longevity of the tree fine roots,and play an important role in the process of forest ecosystem circulation of materials and energy flow.Finding out the soil moisture,nutrient and the interaction between them,as well as dynamic and turnover of the fine roots are essential in appraising forest ecosystem circulation of materials accurately.The research progress of the effects on the soil moisture,soil nutrient,and the interaction between them and the dynamic and turnover of the fine roots were reviewed.According to the characteristics of forest ecosystem circulation of materials,future main researches were presented： firstly,giving more investigations and experiments on the interaction between soil moisture and the soil nutrient of the fine roots in planted forest;secondly,improving studies on response mechanism of different rank of the fine roots to interaction between soil moisture and soil nutrient;furthermore,promoting the understanding of the influence of interaction to soil microbiology of different types of forest;finally,strengthening investigations of the interaction between soil moisture and soil nutrient of the fine root dynamic and turnover under the background of global changes in different forest ecosystems to provide basis to appraise hydrological cycle and nutrient cycle of forest ecosystem accurately.
