摘要： <正>根据国家林业局城市森林生态系统定位研究下蜀站 1 1 a(1 988.1～ 1 998.1 2 )的日降水观测资料 ,研究平均的降水概况。又从降水量的月、年变率、月极端值的增减率、降水等级达大雨以上和连阴雨雨量等方面研究了 3种林分的透流情况 ,以说明城市森林中透流的特点

Abstract: The summary of the precipitation at the located station was studied from 1988 to 1998. In addition, the throughfalls at three stands were studied in the rates of the monthly and annual rainfall changes, the rates of the monthly extremum changes, the continuous overcast rains etc., which illustrates the throughfall characteristic of the microclimate in the city forest.
