摘要
The intercepting dynamic processes of P.tabulaeformis forest canopy have been studied by local measuring methods for evaluating 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 has 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 combination of linear and sine
