摘要

以小兴安岭北部公别拉河流域上游沼泽湿地为研究区

选择典型的乔木沼泽、灌木沼泽和草本沼泽

对其土壤Cu、Zn含量进行研究.结果表明:3类沼泽土壤全Cu含量表现为:灌木沼泽＞乔木沼泽＞草本沼泽

而有效Cu含量则表现为:乔木沼泽＞灌木沼泽＞草本沼泽

同时有效Cu具有C层＞B层＞A层的特点.全Zn含量在不同类型沼泽间变动较小

而有效Zn含量则表现为草本沼泽＞灌木沼泽＞乔木沼泽.乔木沼泽和灌木沼泽表层土壤全Cu含量的季节变化呈单峰曲线

而草本沼泽表层则有较大的波动性

各类沼泽C层全Cu含量变化较小.3类沼泽各层土壤全Zn含量季节变化基本一致

均呈波动式上升趋势.pH值对土壤Cu、Zn含量影响较大

呈相关极显著

而有机质含量对其影响较小.

Abstract

Base on the study of Cu and Zn contents of typical arborous mire

scrub mire and herb mire of upper reaches of Gongbiela river watershed in the northern of Xiaoxing'anling

the results showed that the total Cu content appeared scrub mire > arborous mire >herb mire

but the valid Cu content showed arborous mire >scrub mire >herb mire

and at the meantime the characteristic of valid Cu content in the soil layer showed C layer >B layer >A layer;The content of total Zn in the different types of mire was insignificant

but the valid Zn content showed herb mire >scrub mire >arborous mire.The seasonal fluctuation of the surface soil total Cu content of scrub mire and arborous mire appeared a single peaked curve

but it showed great fluctuation in herb mire.There existed a similar trend for seasonal fluctuation of total Zn among three different types of mire

i.e.

was the total Zn in the different soil layers tend to increase wavily.The soil pH had a very significant correlation with soil Cu and Zn contents

but the content of organic matter didn't.
