In order to determine the relationship between influencing factors and canopy interception of Phyllostachy edulis forest, the canopy interception and influencing factors were studied with location fixed observation method from April 2012 to March 2013. Results showed that the throughfall, stemflow and canopy interception accounted for 60.6%, 6.7% and 32.7% of total precipitation during the study period. Canopy storage capacity and stem storage capacity of Phyllostachy edulis forest were 0.82 and 0.1 mm, respectively. Leaf area index(LAI) was introduced as a canopy characteristic and the correlation between LAI and canopy interception was analyzed. Canopy interception of each month increased with the increase in mean monthly LAI to some extent. Mean monthly canopy interception rate decreased with the increase of mean monthly LAI outstandingly. The environmental factors influencing canopy interception were evaluated by gray relational grade which showed an order as: rainfall intensity > precipitation > wind speed > temperature > wind direction > air humidity, while the order of the environmental factors influencing canopy interception rate, as evaluated with the same method, was: temperature > wind direction > precipitation > wind speed > rainfall intensity > air humidity.
