内蒙古东北部呼伦湖沉积物柱样的花粉组合资料描述了全新世东亚季风边缘植被和气候的变化。干草原占主导地位的湖盆从约。11，000至8000 cal yr BP，表明气候温暖干燥。草和白桦林扩大8000至6400卡年BP，这意味着季风降水显着增加。6400 ~ 4400 cal yr BP，气候变冷变干。藜科占主导地位的区间从4400至3350卡年BP，标志着极端干燥的条件。蒿恢复3350-2050卡年BP，表明气候条件的改善。温度和降水量下降2050至1000卡年BP减少蒿和松树林的发展所示。在过去的1000年里，人类活动可能对湖区的环境产生了重大影响。我们认为，由于北方半球残留冰盖的存在，东亚夏季风直到8000 cal yr BP才开始增强。季风降水在千年至百年尺度上的变化与热带太平洋的海洋-大气相互作用有关。
Pollen-assemblage data from a sediment core from Hulun Lake in northeastern Inner Mongolia describe the changes in the vegetation and climate of the East Asian monsoon margin during the Holocene. Dry steppe dominated the lake basin from ca. 11,000 to 8000 cal yr BP, suggesting a warm and dry climate. Grasses and birch forests expanded 8000 to 6400 cal yr BP, implying a remarkable increase in the monsoon precipitation. From 6400 to 4400 cal yr BP, the climate became cooler and drier. Chenopodiaceae dominated the interval from 4400 to 3350 cal yr BP, marking extremely dry condition. Artemisia recovered 3350-2050 cal yr BP, denoting an amelioration of climatic conditions. Both temperature and precipitation decreased 2050 to 1000 cal yr BP as indicated by decreased Artemisia and the development of pine forests. During the last 1000 yr, human activities might have had a significant influence on the environment of the lake region. We suggest that the East Asian summer monsoon did not become intensified until 8000 cal yr BP due to the existence of remnant ice sheets in the Northern Hemisphere. Changes in the monsoon precipitation on millennial to centennial scales would be related to ocean-atmosphere interactions in the tropical Pacific.
