The global climate underwent tremendous changes during the transition from the Last Glacial Period to the Holocene. At almost the same time, human society transitioned from the Paleolithic to the Neolithic. Therefore, the rela-tionship between climate change and human activity during this period has become a research hotspot. Yunnan Province is a region with a great abundance of Paleolithic archaeological sites in China; however, Neolithic sites are relatively few. There has also been relatively little research on paleoclimatic conditions during the Paleolithic-Neolithic transition in Yun-nan. Phytoliths, as a highly durable and long-lasting form of plant microfossils, can be an important means for reconstruct-ing paleoclimates. In this study, we examined the Naminan site in Jinghong, which was occupied during the transitional period from the Paleolithic to Neolithic. Based on our analysis of the phytolith record at Naminan, we reconstructed the climatic conditions for each of the archaeological strata and discussed possible human activities. The results show that Naminan experienced a sequence of warming followed by cooling and warming, which is consistent with previous paleo-climate research in other areas of Yunnan Province.
