The Huaihe watershed is the semi-humid climate region located in the North and South transition zone of the Eastern China. In the region,both winter and summer monsoons play an important role in climate and environment. There are loess depositions which dusts were transported by the winter monsoon from the northwestern arid and semi-arid areas and the rich precipitation of Jianghuai-specific plum rains, directly related to the summer monsoon. However, the climate of the region is different from both the North and the South of China. Therefore, the revealing paleo-climate change of the region is particularly important for understanding of the paleo-climatic pattern of the Eastern Asia. In history, the Yellow River had diverted into the Huaihe basin and flowed into the East China Sea. Because the Yellow River-carried sand and clay formed thick depositions in most regions of the Huaihe basin,it is an important issue to find a continuous Holocene wind-blown loess section in the region. In the study, a Holocene loess-paleosol section (33.95021° N, 113.47992° E; 96m a. s. 1.) in Xiangcheng County, Henan Province of the northwest of the Huaihe basin was chosen to analyze the Holocene climate. The loess section located on a loess platform in the piedmont of Funiu Mountain, about 10km far from the Wohe River ever diverted by the Yellow River. The wind-blown dusts of the region come from the same source areas as that of the Loess Plateau. The top about 2.5m of the loess formation was sampled at a 2cm interval. Its 0 ~17cm is the light-brown farmed soil layer. The 17 ~ 35cm part is a loess thin layer and the 35 ~110cm consists of a dark grey paleosol layer with rich organic matter. The part below 110cm is loess in which a lot of small calcium nodules developed. The age of the section is determined by organic carbon ~(14)C dating and suggested for 12.5ka B.P. in bottom of the section. The section was analyzed on the basis of dust settlement dynamics. The Holocene climate fluctuations are discussed according to several indices such as proxies of the dust transported distance,wind strength,spring nearsurface air-temperature and effective moisture. The major conclusions are summarized as follows:(1) The whole trend of the Holocene climate evolution of the Huaihe region was the inverse of the North arid and semi-arid region. The Holocene optimum period of the North dust source region was 7.0~3.8ka B.P. but the optimum period of the Huaihe region was 3.8~1.8ka B.P. that was late than the dust source regions. (2) In the Huaihe plain, the wind strength continually weakened but the moisture constantly increased during the Holocene period. Loess deposition over the last 1800 years was due to the expansion of dust source regions not the increase of wind strength. (3) The characteristics of the Holocene climate change of the Huaihe region may result from that the northward-moving of the plum rains belt was caused by the weakening of winter monsoon and the increased plum rains was due to the westward expansion of the West Pacific subtropical high and the weakening of the India summer monsoon in the Holocene period.
