The distribution pattern of precipitation can be changed when it passes through the canopy due to the interception of the forest canopy, which is a complex hydrographical process and is affected by precipitation and forest characteristics. In order to find out the features of canopy interception, the research which used the bamboo(Phyllostachys edulis) as the research object was conducted in the hill areas of southern Jiangsu province, to analyze the rainfall, and the relationship between the rainfall intensity and canopy interception of rainfall through the data of the rainfall events observed in 2007. The results were as follows:(1) During the research period, 102 precipitation events were observed, and most of the rainfall events featured with low intensity and moderate precipitation, the total annual precipitation was 1110.8mm and the average single precipitation was 10.89mm. However, the maximum rainfall was 110.0mm,and the minimum rainfall was 0.55mm.(2)The total amount of canopy interception was 171.72mm, it accounted for 15.46% of the total rainfall over the same period. Single canopy interception ranged from 0.21-4.55mm, volatility varied from 1.3%-100%. When the single rainfall outside the forest increased, the canopy interception gradually reduced, the correlation could be fitted by power function(I₀=117.34P^-0.9106).(3)When the single precipitation outside the plantation was less than 5mm, the rainfall accounted for 5.0% of the total rainfall of the whole year, and the corresponding events frequency was 9.8%. A positive correlation between the precipitation and the canopy interception of bamboo was observed, and the correlation could be fitted by logarithmic function (I=0.4931ln(P)+0.9493)(R²=0.6108,n =22); however, when the single precipitation outside plantation was more than 5 mm, the canopy interception became larger with the precipitation increasing, so did the variation range and frequency. The range of interception was from 0.21 to 4.55mm, but the correlation between the precipitation and the canopy interception was not significant.(4)When the rainfall was between 7-10mm,the rainfall outside the forest and the canopy interception of the total were 245.14mm and 47.9mm respectively,and both accounted for the largest proportion in the year,separately 22.07% and 27.9%; the relationship between average single interception and mean precipitation could also be described by logarithmic function(R²=0.7287), while the relation between interception rate and precipitation was best fitted by power function(R²=0.9817).This relationship was very significant,but when the rainfall was not very heavy, this relationship was not so significant.(5)When the single rainfall intensity was less than 0.06 mm/min in a year, the frequency of rainfall was 73.53%,57.93% of its total rainfall, canopy interception accounted for 89.34% of its total, the mean interception rate (23.84%) was much higher than that (3.92%) when the intensity was more than 0.06 mm/min during the research period. The results obtained from the present study would provide theoretical foundation for the construction of water-soil conservation forest and water-reservation forest.
