Rainfall interception represents the amount of water trapped in natural cover that is not drained directly to the ground. Intercepted rainfall may evaporate after a rain event, making it one of the main drivers of water balance and hydrologic regionalization. This process can be affected by factors such as climate, altitude, vegetation type, and topography. Here is a simple method of calculating rainfall interception in temperate forests using in Santa Maria Yavesia, Oaxaca, and Mexico as an illustrative study area. We used two rain gauges to measure net precipitation (N_p) under the canopy at each study site and one gauge outside the canopy to obtain gross precipitation (G_p). Throughfall (T_h) was indirectly measured using hemispherical photographs. Rainfall interception was obtained through a combination T_h and G_p and N_p. The mean rainfall interception was 50.6% in the Abies forests, 23%–40% in the coniferous‐mixed forests, and 27.4% in the broad‐leaved forests. We classified rainfall events by intensity to determine the effect of canopy structure and precipitation and found that 75% of the events were weak events, 24% were moderate events, and 1% were strong events. In addition, we found that rainfall interception was lower when the intensity of precipitation was higher. Our method can be replicated in different ecosystems worldwide as a tool for assessing the influence of rainfall interception in terms of ecological services.

基于间接方法的降雨拦截：以墨西哥瓦哈卡的温带森林为例

降雨截留表示自然覆盖物中截留的未直接排放到地面的水量。降雨后，截留的降雨可能会蒸发，使其成为水平衡和水文区域化的主要驱动力之一。此过程可能会受到气候，海拔，植被类型和地形等因素的影响。这是一种以圣玛丽亚·亚维西亚，瓦哈卡州和墨西哥为例的研究区域，计算温带森林降雨截留的简单方法。我们使用两个雨量计来测量每个研究地点的冠层下的净降水量（N _p），并使用一个量规在冠层外的量具来获得总降水量（G _p）。穿透（Ť _ħ）是使用半球照片间接测量的。通过结合T _h和G _p和N _p来获得降雨拦截。冷杉的平均年降雨量为50.6％森林，针叶混交林为23％–40％，阔叶林为27.4％。我们根据强度对降雨事件进行分类，以确定冠层结构和降水的影响，发现75％的事件是弱事件，24％是中度事件，1％是强事件。此外，我们发现当降水强度越高时，降雨的截留率就越低。我们的方法可以在全世界不同的生态系统中复制，作为评估降雨拦截对生态服务的影响的工具。
