Abstract:A study was conducted on Pinus tabulaeformis plantations in the Taiyue Mountain of Shanxi Province to analyze the relationship between canopy interception, throughfall, stemflow and rainfall using data from 30 rainfall events observed from May to September, 2011.The results were as follows: (1) During the research period, the total precipitation was 634.79mm.Average rainfall was 21.16mm, the maximum rainfall was 58.15mm, and the minimum rainfall was 0.54mm.The largest monthly rainfall occurred in August, was 190.77 mm, the minimum monthly rainfall happened in June, was 41.81 mm.(2) The correlation between canopy interception with 0.8 canopy coverage and rainfall was fitted by linear function, while canopy coverage of 0.7, 0.6 and 0.5 were all be fitted by power function.The correlation between canopy interception rate for all canopy coverage and rainfall was fitted by power function.The correlation of all canopy coverage between canopy throughfall, stemflow and rainfall was fitted by linear function.Both of canopy throughfall and stemflow increased with increasing rainfall.(3) Different canopy coverage of Pinus tabuleformis produces different canopy interception, throughfall and stemflow.In general, with the decrease of the canopy coverage, the canopy interception decreased, throughfall increased, and the trunk stemflow increased.Canopy interception showed a positive correlation between canopy coverage, while throughfall, stemflow and canopy coverage showed a negative correlation.(4) The monthly dynamic changes of canopy interception throughfall and stemflow was consistent with that of rainfall.
