Rivers of the Southern Russian Far East:DOC Composition and Landscape Peculiarities
The objectives of this study were:(1) to analyze the concentrations and characterize with UV-vis spectroscopy the compositional heterogeneity of DOC of the rivers in the Western Primorye:the Bikin,Bolshaya Ussurka,Ussury,Razdolnaya and Tumen; (2) to seek possible relationships between landscape peculiarities of the watersheds with the composition of DOC.Our studies allowed grouping the rivers on the qualitative composition of DOC.A trend towards a higher aromaticity of DOC has been shown for the rivers of northern location (the Bikin,Bolshaya Ussurka and Ussury) in comparison with those in the southem Primorye (the Razdolnaya,Tumen).This fact can be explained by the mountainous and forest landscape type of the northern river group and lowland landscape type of the southern rivers.Additionally,the watersheds of the Razdolnaya and the Tumen are characterized by humate humus type of soils,basalt rocks and by a significant anthropogenic load in this region.
