The coring was successfully operated on the winter ice-cover of the lake in 2000 and the pioneer practice of the ""off-the-ice"" coring proves to be very useful and economic for taking quality cores from lakes in northern China.A multidisciplinary investigation has been carried out on core HQH4, one of the three 11-m-long cores. Results from previous investigation include lithostratigraphy, radiocarbon dating, paleoecology of Ostracoda, stable isotopic record of ostracod shells, total nitrogen and organic carbon, C/N ratio, 81 C of organic matter etc.

To summarize molecular, morphology, chromosome and pollen characters, the conclusion was reached that Epimedium was an nd monophyletic taxon. To divide the genus into any groups would be artificial. It is proposed that the disjunction by space, climate and seas were the main reason of respectively differentiation of each group by the view of geographic and climate changes in the temperate zone of the world. Because of its evolution-conservation, the disjunction did not bring about obvious divergence on the level of molecular and morphology.
综合分子特征和形态、细胞学、孢粉学等性状,提出淫羊藿属是一个进化上极为保守的、自然的单系的植物类群,进行属下任何阶元的划分都将是人为的,从旧世界温带的地质变化及气候变迁的角度推测,空间、气候和海洋的隔离是产生类群各自分化的主要原因,但由于其进化上极度保守,这些隔离尚未产生出类群间形态上和分子水平上的明显趋异。

Through the analysis and contrast between HM core and Dh core, combined with the data of AMS14C, six pollen assemblages were ploted Out. At the mean time, six stages about the vegetation change and climate fluctuation were rebuild. In addition, there were three sub-assemblages ploted out in the Atlantic period, Sub-Boreal period and Sub-Atlantic period, which reflected the less vibration of the large-scale climatic change. Pollen assemblage dominated by Concentricystes in the hard and green clay of late Pleistocene can make it sure that the hard green clay layer was formed by water.
