摘要

The intercepting dynamic processes of P. tabulaeformis forest canopy have been studied by local measuring methods for e valuating forest benefits of soil and water conservation and explaining mechanism of soil and water conservation. The result showed that interception amount of the canopy averaged in six-years was 104.8mm and interception rate was 23.7 %. The intercepting processes have a limited increasing processes with raining time. The maximum value of interception amount occurred in the middle process. Then intercepting amount changes like a wave, which can be described using the combina tion of linear and sine functions.
