摘要

对黑龙江省东部山地樟子松人工林(P inus sy lvestr is var.m ongolica)生态系统的大气降水、穿透水、树干径流和枯透水中的pH值、溶解氧、浊度、电导率、氧化还原电位、钾、钠、钙、镁、铜、锌、锰、铁等水质指标进行了观测

结果表明:大气降水经过林冠层后

水化学特征发生了明显变化

pH逐层降低

经过枯枝落叶层后

水质的酸化得到了缓解

说明樟子松人工林的枯枝落叶层对水质酸化有很好的缓冲作用。穿透水、树干径流和枯透水的COND变化趋势相同

且各月树干径流和枯透水的COND平均值均高于穿透水和大气降水。枯透水各月ORP的平均值明显低于大气降水和树干径流

可见樟子松人工林的枯枝落叶层对ORP值的降低有很好的作用。樟子松人工林对于增强水中微量元素F e和M n含量也有很好的作用。

Abstract

The water quality in rainfall

throughfall

stemflow and litterthrough in the Pinus sylvestris var.mongolica at Eastern mountainous region in Heilongjiang province has been studied.The indicator include pH

TURB

COND

ORP

Mn and Fe.The results show that the chemical properties of rainfall has been changed after it passing through forest canopy.The pH is lower than those of rainfall.After through litter

the acidification of water is better.The results suggest that the litter of Pinus sylvestris var.mongolica has better buffering ability of water acidification.The change of COND is similar in the throughfall

stemflow and litterthrough.And the average of COND in the stemflow and litterthrough is higher than that in the rainfall and throughfall every month.The average of ORP in the litterthrough is lower than that in the rainfall and stemflow.So the litter of Pinus sylvestris var.mongolica is better to reduse the ORP.And the Pinus sylvestris var.mongolica is better to increase the content of Fe and Mn in the water.
