Abstract: In this paper a comment on "A Preliminary Analysis on the Quaternary Glacial Climate in the Eastern China Mountains" by Fu Yexian has been given. We conclude that the-re was no climatic environment for the development of mountain glaciation in Lushan du-ring the late Pleistocene period. The existence of coniferous forest-Abies, the dominant species on the low land of East China during the Lushan glaciation (Riss) is an essential premise for Mr. Fu's paper, however, there is no reliable evidence to support it. The data available now can only suggest that the dark mountain coniferous forests at that time lay much lower than today, but still grew in the uplands instead of the low land where deciduous broad-leaved trees were predominant. Mr. Fu believes that the conditions of atmospheric circulation of the ICE AGE were favourable for precipitation in the lower reaches of the Yangtze River. This conclusion is in contradiction with Quaternary geological records in the monsoon area of China, because loess was accumulated in the cold and dry glacial period. Mr. Fu's calculated results of ice budget near Guling in the Lushan glaciation are also not tenable from glaciological viewpoint. His estimated annual snowfall of 1078 mm did not stand a mean summer temperature as high as 5.7℃. In that case, the mass balance between ablation and accumulation on glacier could not be reached.
