- Abstract:
-
Canopy interception affect the fruit trees on the effective use of rainfall directly,the relationships between canopy interception of Apricot forests and rainfall were studied by field survey and statistical analysis.Results show that the total rainfall was 528.9 mm from June to September in 2008.The rainfall was redistributed by the proportion of throughfall 83.2%,interception 16.0% and stemflow 0.8% respectively.The results show that the relationship between throughfall and total rainfal1 is linear and the relationship between throughfall and interception is Logarithm.Using the improved Horton model,in which the parameter Icm* means rainfall adsorption capacity of canopy(2.139 mm) and α means coefficient of canopy evaporation for this region(6.7%).The improved Horton model explain the law of crown interception composed of three physical processes(adsorption,soakage and evaporation).Simulated values and measured values have a better consistency for a period of time.We conclude that the improved Horton model can be used for estimating canopy water interception in Beijing suburbs Apricot forests.
