Twenty lake bottom surface layers mud and water samples in the Qilihai Wetland Beidagang Reservoir Tianjin were taken to do diatoms analysis. More than 6000 identified divided into 117 species 28 genera. Based on calculation of DAIpo(Diatom Assemblage organic pollution), pollution level can be into: Xenosaprobic, β -oligosaprobic, α -mesosaprobic, from clear slightly cloudy water. The wetland e...
The concept of Genealogical Sorting Indexes (GSIs) was first introduced by Cummings et al. [1]. Given a set of observations belonging to different groups (represented in the form of a hierarchial tree), the Genealogical Sorting Index (GSI) value obtained for a particular group provides a quantitative measure of how closely the observations belonging to this group have clustered in the given tre...
The present study envisaged the dynamic monitoring and of hydrochemistry surface water shallow groundwater in northern part Yellow River Delta, China. Analysis revealed that exhibited two forms: precipitation evaporation type hydrological type, latter was obviously affected by level River. a higher degree mineralization. Cations Mg2+, Na+ K+ anions Cl- SO42- were main ion components total disso...
