里下河地区代表性浅水湖泊表层沉积物可转化态氮的赋存特征
Occurrence characteristic of transferable nitrogen forms in sediments on surface of representative shallow lakes of Lixiahe Region
摘要
Abstract
Taking the small eutrophic lake, which is seriously affected by human activities, as the research object, the occurrence characteristic of transferable nitrogen forms in the sediments on the surface of the lake is studied and the relationship between environmental factors and various forms of transferable nitrogen is explored.The results indicate that:(1) the distribution order of various nitrogen in the four sediments samples from the lake surface was SOEF-N>IEF-N>WAEF-N>SAEF-N;(2) There is obvious relevance between w( IEF-N) and clay, soil, sand and w(Ca); There is obvious relevance between w(WAEF-N) and moisture content, organic matter, w(TP), w( Ca) and w ( Zn ); There is obvious relevance between w ( SOEF-N ) and clay, organic matter, w ( TOC ) , w( NH+4 ) and w ( Mn ); There is only certain relevance between w ( SAEF-N ) and w ( TP ) and w ( Ca ) . (3) w( IEF-N) hold the dominance percentage in TN in big lakes significantly affected by human activity; while the content of WAEF-N is consistent with the amount of organic matter content in the surface sediments.关键词
