The interception of precipitation by vegetation and subsequent evaporation during and after rain events is an important component of the hydrological budget of forest ecosystems, particularly for forests in ecologically and hydrologically sensitive regions such as Qinling National Forest. This forest was incorporated into the State Natural Forest Protection Project and is managed solely for soil and water conservation. The Qinling Mountains are a major mountain range in China and are the major headwater source for one of the three routes of the South鄄to鄄North Water Transfer Project. The evergreen Pinus tabulaeformis is the dominant canopy species at elevations from 1400 to 1700 m. Extensive studies have been conducted to examine the canopy interception, throughfall and stemflow in P. tabulaeformis forest ecosystems across China, mostly in juvenile (臆30 years) or middle鄄aged (31-50 years) plantations. However, information on rainfall
