摘要： 对比研究了亚热带丘陵区几种人工林在对大气降水再分配后发生的水质变化。对P、K、Ca、Mg、Na、S元素的测定分析表明,不同林分具有不同的交换特性,3种人工林中Mg和K、Ca均较容易淋失,而对于P和Na则呈现明显的吸收或吸附作用。

Abstract: This article interprets how rainfall influences the element cycling of artificial forests.Forest hydrological effect of three main artificial forests in red earth hilly area was studied with regard to precipitation chemistry based on complete data from field experiments at Qianyanzhou Ecological Station of CAS.The concentrations and amount of chemical elements including K,Ca ,Na ,Mg ,S and P in stem flow and through fall were studied in forests of sub-tropical zone,mean-while comparisons were made among three main tree species.Concentrations of six chemical el-ements of stem flow and through fall were analyzed.The results showed that different tree species own different exchange characteristics,and Mg ,K and Ca in the three tree species were easily to be leached,but P and Na were absorbed apparently.

Key words: sub-tropic zone, stem flow, through fall, chemical elements, leaching
