运用调查统计和偏冗余方法分析中国温带至亚热带季风气候下的针、阔叶林冠层降雨初次分配特征，并对该生态过程的影响因子进行分析。结果表明：季风气候下，林冠降雨初次分配总体呈现平均透雨率＞截留率＞茎流率的趋势；不同林型、气候带的林冠降雨初次分配差异明显，林冠降雨平均截留率呈现温带＞亚热带、针叶林＞阔叶林的趋势。不同林型间（针叶和阔叶林）主效驱动因子相似，均以森林结构类因子为主，气候类因子居次；不同气候带间主效驱动因子不同，温带为气候类因子，亚热带为森林结构类因子。说明，大尺度下总体呈现气候类因子、森林结构类因子＞地理地形类因子。研究结果可为评估和合理干预森林生态水文过程提供参考。

This paper applied investigation statistics and partial redundancy analysis to analyze the history data related rainfall parti -tioning from temperate zone to subtropical zone of China.It analysed the effect factors of the ecological course.Results obtained dem-onstrated that ,in monsoon climate ,canopy rainfall primary distribution showed that average saturating rain rate >intercept flow rate>stem flow rate.the canopy rainfall initial distribution such as interception loss presented a trend that temperate zone >subtropical zone;coniferous forests >broadleaf forests.And the dominated driving factors of coniferous and broadleaf forests were vegetation structures,meteorological conditions took the second place;different temperate and subtropical zones had different main driving fac-tors,meteorological conditions for temperate zone and vegetation structures for subtropical zone respectively .It showed that meteoro-logical conditions and vegetation structures >geographical and topographical characters.The above results could provide reference for evaluating and intervening reasonably the eco-hydrological process of forests.
