A study on phytoliths and their climate indexes is carried out from Homo erectus' cave deposits in Hulu Cave, Nanjing. Evidence shows that phytolith assemblages of the cave deposits are dominated by the cold resistant types with a lower warm index, reflecting an overall cold inclined climate. This possibly connects the cave deposits with glacial climate to a great extent, which is in accordance with the northern fauna revealed by fossil mammals and temperate climate indicated by pollen assemblages. According to the distributional state of the phytoliths and their climate indexes on 4 profiles in the cave, it is revealed that profiles Ⅰ and Ⅱ display certain cold/warm, and dry/wet fluctuations; profile Ⅲ shows a humid and cold condition with the highest humility in the cave deposits; while profile Ⅳ indicates a possible quick accumulating process because of its stable climate indexes except for its bottom and top.
