Interception is one of the most important hydrological processes. Most investigations merely focus on canopy interception, but forest floor interception should also be considered. The stand age also influences interception. | Turkish Journal of Agriculture and Forestry Research Article Turk J Agric For (2013) 37: 495-504 © TÜBİTAK doi: Intercepted rainfall in Abies fabri forest with different-aged stands in southwestern China 1,2,3 1,2, 4 1,2,3 1,2,3 Xiangyang SUN , Genxu WANG *, Yun LIN , Linan LIU , Yang GAO Institute of Mountain Hazards and Environment, Chinese Academy of Sciences, Chengdu 610041, .

Most investigations merely focus on canopy interception, but forest floor interception should also be considered. The stand age also influences interception. To explore the interception characteristics of Abies fabri with different stand ages, canopy, stem, and forest floor, interceptions were evaluated during the rainy season of 2009 (from May to October 2009). The total interception rates were found to be , , and for young, middle-aged, and mature forest stands, respectively. Forest floor interception accounted for , , and of the total interception, respectively. We concluded that the differences among the interceptions of the forest stands were correlated with the leaf area index. A higher stand height also reduced the rate of forest floor evaporation. The water-storage capacities of the young, middle-aged, and mature forest stands were , , and mm, respectively. These results implied that the canopy and forest floor interceptions were related to .
