Abstract: Environmental evolutions in the eastern China have the hollowing characters: 1. Quaternary environmental changes are mainly controlled by global climatic variations. 2. The sensitive regions of environmental changes are between the middle part of Northeast China and the middle part of Central China. The environmental variations of the former were between the forest-tundra of cool temperate zone and the deciduous broadleaved forest of warm temperate zone, and those of the latter were between the broadleaved forest with grassland of warm temperate zone and the broadleaved evergreen forest of south subtropic zone. 3. The coldest and dry climate appeared about 18000-15000 years ago in Late-Pleistocene, When the annual average temperature decreased about 8℃ compared with that of today, and the natural environmental zones moved southward about 1000 km in Northeast China and North China. The hottest and wet climate appeared in middle Pleistocene, when the temperature increased 4℃ compared with that of to-day and natural environmental zones moved northward about 700 km in North China. 4. The general tendency of Quaternary environmental variations was to become dry and the continentality of climate was from strength to strength in the eastern China during Quaternary. 5. The natural environmental variations of the southern part of Central China and South China were smaller than those to the north of them, and the tempertural variations were about 3-5℃ 6. We found that the sporo-pollen assemblages in the "glacial boulder clay beds" of Mt. Lushan and Huangshan all belong to warm and wet forest environment, There fore, the problem of glaciation in Mt. Lushan and Huangshan is questionable.
