The Diatom Paleolimnology Data Cooperative (DPDC) is a database of diatom and associated ecological and paleolimnological data useful in studying global change.

古湖沼学数据库（DPDC）为全球变化研究提供了有关物数据、古湖沼学和其它生态学数据和记录等。

We propose that As anomalism in groundwater possibly resulted from the combined effects of organic matter-enriched lacustrine sediments, geological setting and topographical characteristics.

通过研究，可以看出以还环境为主的富含有机质的湖沼相沉积环境、特定的地质、地形条件为地异常的因。

Site soils in southern area of Jiangsu province belong to washland sediment or limnetic facies sediment.The components of sediment are very complex and process of sedimentation is in disorder.

苏南地区场地土主要为漫滩相、湖沼相或冲湖相新近沉积软弱土,结构松散,沉积零乱,成分复杂,饱可液化粉细砂层及粉土层较为发育,在地震或动力荷载的作用有可能发生软土震陷或砂土液化。
