Abstract：According to the synthetic study on variety of climatic and environmental proxies in Niya section, and the results of other sections in Tarim basin, we reconstructed the characteristics of paleo-climatic and paleoenvironmental evolution in Tarim basin since about 4.0 kaB. P.. Since the last 4 000 years, the area of Tarim basin has experienced alternations of relative cold-moisture and warm-dry: 4.0 kaB. P.-3.45 kaB. P., and the climate was generously inclined to be moisture with the passable water condition. There was the tendency of drought at the later stage: 3.45 kaB. P.-2.50 kaB. P., temperature rose, and the climate became dry. It appeared to be the characteristics of warm-dry climate in 2.50 kaB. P.-1.90 kaB. P., and it was cold-moisture with good water condition, which was beneficial to the growth of crops. During 1.90kaB. P.-1.40 kaB. P., relative warm-dry in climate, the conditions of the climate and environment relatively worsen. During 1.40 kaB. P.-l.OO kaB. P., temperature descent, and precipitation increased. There was a good combination of water and heat. Duringl.OOkaB. P.-0, it was dry in climate mainly, with several cold-warm fluctuations. In the paper, we also renewed the changes of man history on the base of history documents and archaeological excavation. Through the contrast between the paleoenvironmental evolution and the changes of man history, we can find that paleoenvironmental evolution coincide with the changes of man history greatly. In the relative humid term, the environment was in order and was adapted to the human activities, and the agriculture and the stockbreeding became more prosperity. But in the dry and warm term, because of reducing of moisture, the human activities were inhibited, so the agriculture were poor harvest; the environment and conditions of human survival worsened; the old casttes were deserted.
