The importance of fog precipitation in the alpine hydrological and matter cycle processes of Pinus pumila Regal canopy and rain interception was evaluated at Jodo-daira (36.6N, 137.6E, 2839 m a.s.l.) on a summit of Mt. Tateyama, central Japan in summer (August and September) for three years. The mean monthly rain and fog precipitation were 272.1 mm/month and 191.2 mm/month, respectively. The mean rainfall interception by P. pumila canopy was about 20%, but the canopy captured fog precipitation even in the absence of rainfall. At the top of the mountain, relative humidity was almost reaching 100% in the late afternoon every day, and drenched period of the canopy was long. Using delta18O and deltaD analysis, the mean contribution of fog water to the throughfall was estimated at approximately 35%, consistent with the result from direct measurement. These results indicate that P. pumila should have a significant influence on the local hydrological processes of the high mountain ecosystem.

在日本中部立山山顶的朱道寺（36.6N, 137.6E, 2839 m a.s.l）进行了为期3年的夏季（8月和9月）雾降水在矮松林冠层水文和物质循环过程中的重要性以及雨的截留。月平均雨、雾降水量分别为272.1 mm/月和191.2 mm/月。雨蓬的平均截留量约为20%，但即使在无降雨的情况下，雨蓬也能截留雾降水。在山顶，每天下午晚些时候相对湿度几乎达到100%，冠层浸湿期较长。使用delta18O和deltaD分析，估计雾水对穿透的平均贡献约为35%，与直接测量的结果一致。这些结果表明，矮叶茅对高山生态系统的局部水文过程具有重要影响。
