Abstract: A great number of geologic records has shown that the climatic environment in Xinjiang in the Holocene was mainly characterized by warm-dry, although alternated with sub-fluctuations, several important boundaries of environmental changes can also be determined as follows:12, 000 a B.P., 9000 a B.P., 3000 a B.P., 1500 a B.P.and 400 a B.P.Since the Holocene, Xinjiang has undergone the influence of two kinds of environmental development patterns(the westerly type and the monsoon type), so the hydro-thermal disposal here was much more complicated.Generally speaking, the neoglacials of Xinjiang are characteristics of cold(cool)-humid and in the Climatic Optimal, it is dominated by warm-humid conditions in spite of being intercalated several sub-fluctuations of warm-dry intervals.
