Abstract

Angulinao Lake is the biggest lake in the Bashang area, Hebei Province. It lies in the southeast edge of Inner Mongolia Plateau, belonging to arid, semi-arid climate areas. And this enables its deposits to record the climatic and environmental changes sensitively. A multi-proxy investigation of a sediment core from Angulinao Lake reflects climatic and environmental evolution of the catchment over the past 400 years. On the basis of the analysis of grain size, carbonate content and total organic(TOC)content, Three environmental stages are identified. From 1634 to 1801 A.D., detrital grains and the high carbonate contents in sediments suggests the lake became shallower as a result of the dry climate. From 1801 to 1889 A.D., evidenced by thinner grain size and lower contents of TOC and carbonate, the climate became colder and moister and the lake area expanded, which is interpreted as the last fluctuation of the Little Ice age. From 1889 A.D., sediments become coarser with the rapid increase of TOC and carbonate contents, indicating a time when the climate was getting drier and drier, warmer and warmer. In all, the envirmonmental evolution in the Angulinao area over the past 400 years is charactered by the alternating of the warm-dry and the cold-humid climate. Also, the clear warm-dry trend of the lake area can be seen over the last 100 years.
