摘要: 以小兴安岭凉水自然保护区内的阔叶红松林、云冷杉林和落叶松人工林为研究对象, 于2006年3—10月, 分析了其溪流水化学特征的动态变化. 结果表明: 不同月份3种森林群落溪流水的主要阳离子含量均表现为 Ca2+>Na+>K+>Mg2+, 主要阴离子含量均为HCO3->SO42->NO3->Cl-;不同群落类型的主要离子含量影响显著, 3种森林群落溪流水中Na+、Ca2+、Mg2+、Fe2+和Fe3+平均含量为云冷杉林>落叶松人工林>阔叶红松林, 而K+为落叶松人工林>云冷杉林>阔叶红松林; 主要阴离子平均含量均以落叶松人工林溪流水中为最高.

Abstract: Stream water samples under the Korean pine broad leaved forest, spruce fir forest, and larch plantation in Liangshui Nature Reserve of Xiaoxing’an Mountains were collected monthly from March to October 2006 to study the dynamic changes of their hydrochemical characteristics. The results indicated that the content of major cations in the streams was in the sequence of Ca2+>Na+>K+>Mg2+, and that of anions was HCO3->SO42->NO3->Cl-. The average content of Na+, Ca2+, Mg2+, Fe2+ and Fe3+ was in the order of sprucefir forest>larch plantation>Korean pine broadleaved forest, while that of K+ was in the order of larch plantation>spruce-fir forest>Korean pine broadleaved forest. The average monthly content of anions in stream water was the highest under larch plantation.
