| 摘 要： | 基于苹果树冠层截留的观测数据,研究了苹果树的冠层截留特征。结果表明,①果树冠层截留量、穿透雨量、树干茎流量均与降雨量有着明显的相关性。冠层截留量与降雨量之间呈对数关系;穿透流量、树干茎流量与降雨量之间分别呈线性关系。林外降雨大于1mm时产生穿透雨,大于1.5mm时产生树干茎流。果树冠层平均截留率为18%,冠层饱和截留量为7.5mm。②通过29场降雨试验,获得了适合京郊苹果树的冠层截留模型,并对该模型与常见冠层截留模型的模拟结果进行了对比分析。

| Abstract: | In this paper,the relationship between the canopy interception of apple tree,forest canopy peneration,trunk stem flow and rainfall was investigated based on the data of the surb of Beijing.The result showed that ①as significant correlation among forest canopy interception of apple,penetration flow,trunk flow and rainfall.Canopy interception showed a power function correlation with rainfall and a linear correlation with linear,respectively.When the rainfall is greater than 1 mm,the penetration will appear,and when the rainfall is greater than 1.5 mm,the trunk flow will appear.The average rainfall intercept rate by canopy of apple tree is 18.0%,the saturation interception of canopy is 7.5 mm.②Through the comparison between new model and representative canopy interception model.Obtain a new suitable model of canopy interception of apple tree. |
