Description :
This article discusses the climatic and environmental change in Yanchi Lake, Northwest China since the Late Glacial through a comprehensive analysis of lake sediments. The results show that the lower part of the lacustrine section is formed mainly in the Late Glacial and early Holocene period, while the proxies’ data indicate the lake expansion is associated with high content of mineral salts. Affected by the reworking effect, the pollen concentr. The long-term monsoonal pattern is different from the lake evolution in Central Asia on the Holocene millennial-scale. This research proves the monsoon impacts on the northwestern margin of the summer monsoon, and also proves the fact that the northern boundary of the summer monsoon moves according to millennial-scale climate change.
