The relationship between rainfall and interception by canopy of Picea crassifolia forest

Minxia Liu

Abstract

Through long term and located observation, this paper researches quantitative change of rainfall caused by canopy of Picea crassifolia forest, simulates interception model by canopy of Picea crassifolia forest.The result show that intercepted rainfall by canopy also increases with total rainfall to certain extent. The average rainfall intercept rate by canopy of Picea crassifolia forest is 29.4 %, it diminishes with the rainfall and rainfall intensity and increase with the increase of closing degree of canopy.
