Pollen analysis and charcoal indices of a 153-cm-long lake sediment core from Lake Taibai (TN1 core) in Hubei Provincedisclosed seven stages of the vegetational changes in Lake Taibai drainage area over the past 1500 years. During 520-1310AD, thevegetational changes were mainly controlled by the climatic changes and the influence of human activities on vegetation wasrelatively weak. Stage of 1310-1710AD, the influencing intensity of human activities on vegetation gradually increased, and thestage was a transitional period of main factors from natural control to human activities drive. Since 1710AD, the vegetational changeswere controlled by human activities and the climatic signal from the vegetational changes was relatively weak. According to thepollen assemblage, the climatic changes with three warm periods of 520-720AD, 1050-1310AD and since 1950AD and two coldperiods of 720-1050AD and 1310-1710AD could be speculated.
