| 摘 要： | 基于长期定位观测数据,研究了青海云杉林林冠层截留量及其与大气降水量的关系,模拟出了青海云杉林林冠截留降水模型。结果表明:在一定降雨量范围内,青海云杉林林冠截留量随降雨量的增加而增加;青海云杉林林冠层平均截留降水率为29.4 %,它随降雨量和降雨强度的增大而减小,随郁闭度的增加而增大。

| 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. |
