Abstract:

Lake Liangshanpo is located in the hinterland of Huang-Huai-Hai Plain, the detailed stratigraphic correlation division and regional sedimentary environment analysis can help to construct the project in Lake Liangshanpo.Based on the lithology, grain size, and sporopollen analysis of sediments in ZK1-ZK4 drilling cores of Lake Liangshanpo, along with the results of 14C dating, a new stratigraphic division scheme was established and the sedimentary environment evolution process during the past 1,000 years was reconstructed of Huang-Huai-Hai plain.The Lithostratigraphy, Biostratigraphy, Chronostratigraphy are selected to multiple classify and correlate the strata of Lake Liangshanpo, the results showed that the Ⅰ stratigraphic and Ⅱ stratigraphic belong to Baiyunhu formation; the Ⅲ stratigraphic, Ⅳ stratigraphic and Ⅴ stratigraphic are divided into the Juye formation.The elimate of the Ⅰ stratigraphic (formed in 750-900 AD) of Lake Liangshanpo relatively cool and dry, which was a sedimentary marsh environment; the sedimentary environment of the Ⅱ stratigraphic (formed in 900-1,200 AD) was a deep lake facies, and the climate became warm and humid; during the formation period of the Ⅲ stratigraphic (formed in 1,200-1,300 AD), the climate was warm and humid, and the sedimentary environment was fluvial facies; the sedimentary characteristics found in the Ⅳ stratigraphic (formed in 1,300-1,500 AD) indicate that the sedimentary environment is a disturbed and stable deep lake environment, and the climate changes from warm and humid to cool and dry; the sedimentary environment of the Ⅴ stratigraphic (formed in 1,500 AD till now) changed from lake facies to fluvial facies, and the climate was cold and dry.

Key words: sedimentary environment, stratigraphic division, Baiyunhu formation, Juye formation
