| Abstract: | 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 b... |
