Argument on and Future of the Problems of the Pleistocene Glaciers in the Eastern Part of China

Controversy over the question whether glaciation developed or not in the middle and lower mountains of East China in the Quaternary period exits for more than half a century. Supporters of pan-glaciation suggest that the ancient glaciers distributed widely from Daxinganling in Northeastern China to Guangdong and Guangxi provinces in Southern China as well as along the coasts of Fujian and Zhejiang provinces in East China,while opposers hold that the Quaternary glaciers occurred only in those mountains higher than 3500 m,such as Taibai Mountains in Shaanxi province and Yushan Mountains in Taiwan province in Late pleistocene and that no reliable glacial evidences are found in other regions. We think that the disparity originates, in fact, from different conceptions on the indict-ors of glaciation. At present,the divergence is wide and profound in the following points; 1. The origin of some landforms and deposits involving the theory on geomorphology and sedimentology, the key point to solving the probems; 2. The quaternary environment, an important problem; 3. The conditions of glacial formation needing uniformity of recognition; 4. The ecological conditions for the development of plant and animal communities; 5. The periglacial phenomena and their retations to glacier; 6. The weathering and soil formation as well as chemical weathering in post-glacial period; 7. The significance of climatic strata and the principles for dividing the quaternary strata.
