    摘要:

    对东灵山地区大气降水特征及森林树干茎流进行了研究,结果表明:年降水量大部分集中在6~9月份,日降水以量级低于5.0mm的小雨较多;单次降水以雨强小于2.0mm的阵性降水为主。单株树木的干流量以辽东栎(30.3mm)最大,棘皮桦(2.9mm)最小;两个生长季各林分的干流深是:辽东栎林66.68mm,35.19mm;落叶松林43.76mm,23.12mm;混交林32.77mm,17.36mm;油松林22.15mm,11.75mm。各森林类型的干流量S与降水量P和前24h降水量P1呈显著正相关关系。

    Abstract:

    Studies on characters of precipitation and forest stemflow in Dongling Mountainous area were carried out.The results indicate that:eighty percent of annual precipitation falls within the period from June to September,and it consists of frequent,small and low intensity rains. Quercus liaotungensis produces the largest stemflow per tree among the four species,and Betula dalurica produces the smallest.Depth of stemflow of four stands in 1996 and 1997 is 66.68mm,35.19mm;43.76mm,23.12mm;32.77mm, 17 36 ...
