| 摘 要： | 利用林内外降雨观测资料，分析了子午岭林区4月—10月林内降雨量、林冠截留量、林冠截留率与林外降雨指标的关系。其结论为林内降雨量与林外降雨量呈直线正比关系；林冠截留量与不同雨量级呈幂函数关系；影响林冠降雨截留率的最好降雨指标为 PI30。

| Abstract: | Rainfall under forest from April to October,crown canopy interception and relation between crown canopy interception and rainfall index in the non-forest have been analysed in this paper,The results have shown that rainfall under forest is positive line relation to rainfall in the non-forest,Correlative relation between intercepting amount of crown canopy and different rain-fall class is power function,Best rainfall index of affecting on crown canopy interception is PI30. |

| Keywords: | the Ziwuling forest area rainfall under forest crown canopy interception rainfall index |
