1987年夏天，在墨西哥东北部的半干旱植被群落中，测量了个别灌木ofDiospyrus texana，Acacia farnesianaandProsopis laevigata的截留损失和降雨再分配。在此期间，有17场风暴产生了230毫米的降水量。平均净降水量为167.6 mm，其中穿透雨160.5 mm，树干茎流7.1 mm，截留损失占总降水量的27.2%。树干茎流在种间和种内均存在显著差异。德克萨斯州。在40 mm h− 1的模拟风暴中，D种的茎流输入平均为321和115 ml min− 1。得克萨斯州和A. farnesiana-P. laevigata）。树干茎流扩散的理论面积平均为0.320 m2，扩散距离平均为0.115 m2，扩散距离平均为0.30，扩散距离平均为0.15 m。这些地区的年降水量分别为3030和2650毫米。
Interception loss and rainfall redistribution were measured in individual shrubs ofDiospyrus texana, Acacia farnesianaandProsopis laevigatafrom a semi-arid vegetal community in northeastern Mexico in the summer of 1987. In this period 230 mm of precipitation were recorded from 17 storms. Net precipitation averaged 167.6 mm, of which throughfall formed 160.5 and stemflow 7.1 mm. Interception loss was 27.2% of the total gross precipitation. Significant differences in stemflow were noted both among species and within the speciesD. texana. Stemflow inputs averaged 321 and 115 ml min−1for a 40 mm h−1simulated storm for the speciesD. texanaandA. farnesiana-P. laevigata, respectively. The theoretical areas and distances over which stemflow spread averaged 0.320 m2and 0.115 m2and 0.30 and 0.15 m, respectively. These areas were calculated to receive 3030 and 2650 mm as annual precipitation.
