Abstract：The abundant Neolithic sites advantage for the historical environmental research in the Dongting Lake area. The Dongting Lake has experienced several change process since last ice age. From later Pleistocene to early Holocene the Dongting Lake area was a plain cutting by deep channel. Then the anthropologic has been to the Dongting Lake area frequently since the globe change warmer in Neolithic time. The Zaoshi civilization shows the human activity almost in the periphery of the Dongting Lake area and the Daxi civilization indicates the advance to the center of the Lake area for fishing and hunting. It was warm and flooding in the Qujialing civilization time, and human being retreated from the lake area. Since the Longshang civilization time, it was cool and precipitation reduced, and ther human activity moved to the center of the lake area. The lake's delta developed and lake's surface decreased. From then to the Han Dynasty, the delta plain developed and small lakes and swamps formed. Since the Wei and Jin Dynasty the lake expanded especially by the Yangtze River distribution to the Dongting Lake. The Dongting Lake shrunk by almost two thirds of its area of a century ago, which attributed to natural siltation from upstream sediment source and intensifying human impact, such as reclamation and aquaculture, and also lead to the lake storage capacity lost quickly.
