摘要

降水是森林生态系统的一个主要的养分输入源

观测并分析降水化学对于准确地估算森林生态系统养分循环的养分元素浓度显得极为重要。对冀北山地华北落叶松林穿透雨、树干茎流和枯透水中的Ca、Fe、K、Mg、Mn、Zn共6种养分元素进行了测定。结果表明:(1)大气降水经过林冠层后其水化学特征明显发生了变化

化学元素含量均有不同程度增加

含量排序为Ca>K>Mg>Fe>Mn>Zn

其中Mn元素的增长倍数最多

但6月份Mn和Zn元素浓度都出现负增长。树干茎流各项指标均增长很多

化学元素含量排序为Ca>K>Mg>Mn>Fe>Zn。枯落物水中K和Ca元素浓度增加最大。(2)大气降雨中Zn的变异系数最大

达2.853;K和Ca元素的变异系数最小

为0.158

0.163。落叶松林穿透雨、树干茎流和枯透水中最大变异系数分别为Fe元素3.115

Mg元素为1.288

Fe元素为2.139。(3)经过淋洗后水样中各元素的浓度均有所增加

穿透水、树干茎流和枯透水中K、Ca增加较多

Fe、Zn的淋溶量较少。

Abstract

Because of precipitation serves as one of major approaches of nutrient input into the forest ecosystem

the accurate measurement of its volume and ion concentration is of prime importance in an evaluation of nutrient biogeochemical cycle.The contents of six nutrient elements(Ca

Zn) in through-fall

stem-flow and litter water were measured in the larch forest of North Mountain of Hebei Province.The results showed that:(1)Precipitation canopy layers after its hydrochemistry characteristic obviously c...
