摘要: 长白山自然保护区是目前我国最大的自然保护区,也是国际生物圈保留地网之组成部分。长白山是一座休火山,在火山锥体的顶部中央处,有一地势凹陷的火山口,积水成湖,这就是驰名中外的长白山天池。天池是中朝两国界湖,也是我国东北海拔最高的湖泊。至今基本未受人类生产活动的直接影响。湖水的化学组成状况主要受控于自然因素,因此,开展天池水化学组成的研究,对于森林生态、环境保护、地质找矿,以及表生带化学元素迁移途径和机理的阐明等都具有十分重要的意义。

Abstract: Up to now the natural reserves of Mt.Changbai is the largest inChina,and it is also a component part of the MAB Program.Tian-chiof Mt.Changbain is a boundary lake situated between China and Korea,and it is also the source of the Songhua River.It is very significant tothe environmental protection and the ecology of forest to study thechemical composition of water in Tien-chi Lake.In this study,different techniques and methods have been employed,50 items of the constant and microconstituent elements were determined,the spacial distribution of chemical composition in the lake water wasfound,and the background content of chemical elements of water wascalculated for the first time,and the formational mechanism of thehydrochemistry was clarified.According to investigation and analysis,the content of rare elements,especially rare earth elements as La,Co,etc.,in water of Tian-chi Lake is very high.The consentrations of mostheavy metal such as Cu,Mn,Ni,Zn,Co,etc.,in water approach theClarke values in the hydrosphere.The contents of some heavy metalssuch as Cr,Cd,Hg,Zn,Co,As,etc.,related clos ly to human activityare far lower than the average value of 45 lakes in U·S·A.The content ofPb in water of Tian-chi Lake is particularly high.about 3 times asmuch as the average value of the latter.That is mainly caused by theinfluence of biogeochemical region with higher content of Pb,it hasno relation with environmental pollution.
