Chemical analysis and toxic tests were combined with benthic macro invertebrates community structure alternations. Based on tri-axial graphs together with relevant matrix of decision-making, the initial bio-responsive sediment quality criteria clearly indicated the situation of heavy metal pollution, and showed the dose-response relationships between heavy metal contamination and benthic biotics. Moreover, the SQC may provide some basic material for establishment of sediment quality standards and for follow-up remediation engineering in the area.

Results showed that planktonic Prorocentrum were assembled to onegroup while benthic Prorocentrum were assembled to another group. The percentagesof the bootstrap values were higher than 95%. The results demonstrated that theplanktonic and benthic Prorocentrum should belong to different genus. Furthermore, the resulting phlogenetic structure showed the percentages of thebootstrap values (98%-100%) of Alexandrium in NJ and ML trees were significantlevers and belong to one group, divergently with genus Gonyaulax.

通过分析 17 种甲藻 18S rDNA 序列构建的系统发育树，营浮游生活的原甲藻在显著水平上聚为一类，而底栖种聚为一类，统计置信度均高于 95％，底栖原甲藻和营浮游生活原甲藻在 NJ 树和 ML 树上均为两个分支，且底栖型的分异速度较浮游型迅速，该结果说明原甲藻属中浮游种和底栖种应分属于不同类群。

An accurate timescale derived from benthic foraminiferal δ^18O is crucial to paleoceanographic studies. In global oceans, there are few continuous δ^18O records for the benthic foraminifers which span the past 5 Ma and have time resolution better than 5 ka.

From 6860 to 3170 cal.yr BP,semi-desert steppeexpanded,regional montane forest steppe retreated,suggesting a prolonged warm and dryclimate.Between 3170 and 2340 cal.yr BP,regional forest steppe expanded whereassemi-desert steppe retreated,indicating the climate became cool and wet gradually and thehumidity reached the maximum at the end of this stage.During 2340～1600 cal.yr BP,Poaceae steppe dominated whereas wetland meadow expanded and the montane forest stepperetreated,suggesting a cool and wet climate prevailed,wormwood grass steppe prevailed andthe climatic instability increased after 1600 cal.a BEThe climate and environmental reconstructions by pollen were supported by the diatomrecords.A relative high lake level and moister climate prevailed between 8660 and 7230 cal.yr BP as inferred by the dominance of planktonic diatom genera and high planktonic/benthicratio (〉40).low lake level and dry climate sustained during 7230～2330 cal.yr BP assuggested by the low abundance of planktonic diatom and low planktonic/benthic ratio ～20and the lake returned to high level during 2330～930 cal.yr BP as inferred by there-dominance of the planktonic diatom and the high value of palnktonic/benthic ratio.The pollen-based climate reconstruction was also consolidated by the grain size andPediastrum concentration records.
