摘　　要：通过对淮河流域的安徽蚌埠禹会村典型龙山文化时期遗址的ABYT2004探方厚150cm剖面的27个样品的磁化率、Rb/Sr、粒度和重矿晶体形态等多环境代用指标,以及遗址周围地貌形态演变的分析,结合AMS14C年代全面提取4.5-4.0kaBP龙山文化时期的环境演变信息,探讨环境变迁对该区龙山文化发展的影响机制:(1)4500aBP气候湿润,淮河流域处于高水位,遗址及周边被水淹没,遗址考古学文化尚未出现;(2)4500aBP开始气候趋向干旱,淮河及其支流水位开始下降,龙山文化开始出现和发展;(3)龙山文化中后期环境开始趋向暖湿,降雨量增加,河流水位开始上涨,洪水灾害频发,至4100aBP前后是淮河流域洪灾发生的高峰期,这是大禹治水史实的客观前提;(4)4100aBP后的龙山文化晚期气候开始向冷干过渡,河流水位下降,遗址区农业生产受到制约,龙山文化迁移消失。Based on the samples from the west wall of the ABYT2004 at Yuhuicun Site, the environmental substitute indexes such as the grain-size, Rb/Sr, heavy-mineral （Zircon） and magnetic susceptibility were analyzed. The age of archaeological stratigraphy was determined by the AMS^14C. The results reveal that the environment evolution induced to the climate changes from 4.5kaBP to 4.0kaBP, Longshan Culture Period. Besides, the information of the ancient human activities and the cultural heritage data withdrawn from the Longshan Culture archaeological stratigraphy, shows that the Longshan culture development was an influenced mechanism. Archaeological excavation shows the following in the study area： （1） In the period before 4500aBP, from 4500aBP to the middle of the period of Longshan Culture, to the later period of Longshan Culture and to 4000aBP, most parts of the region experienced climate change such as warm and wet, cold and dry, warm and wet, cold and dry. （2） Before 4500aBP of the wet period, the Huaihe River water reached a very high level so that the Yuhuicun Site and the surrounding area were submerged and people could not live in the area around the site. From 4500aBP of the dry period, the water level in the Huaihe River and its branches started to descend. （3） Around 4100aBP, in the later period of Longshan culture, it again became cold and dry, and the river water flooded the land again. During this period, the agricultural activity was destroyed, and Longshan Culture disappeared. （4） The environmental information in sedimentary strata and the historical records from the literature confirmed each other, which reveals the close relationship between the Yuhuicun Site and the ＂Dayu Controlling Flood＂ recorded in historical documents.
