This project has been carried out in Yunnan Province in China both by Japanese and Chinese researchers since 1992 as a part of "Paleo-environmental change in Monsoon Asia" in the Study Area 6 "Change of Paleo-environment" in I.G.B.P.The aim of this study is to make clear the behavior of SW-monsoon in summer and polar front in winter since the last interglacial age, i.e.about 120,000 yrs.B.P., with the aid of analyzes of fissile pollen, landforms, palaeo-soils. Yunnan Province, located on the fringe of the tropical area with very large relative height from 170 to more than 6700m a.s.l., is the most suitable for this purpose.Results of our study for three years are as follows :As to present climate, the fluctuation of annual precipitation, which is clearly relate with EI Nino, is remarkable in the northeastern part of this province. Regression formulas were estimated for precipitation and temperature with the aid of latitude, longitude and topographical factors. Equilibrium elevation of the glaciers was about 4800m a.s.l. on Mt.Meili-xue-shan in the northwesternmost district and about 3300m on Mt.Cang-Shan ca.300km south of the former. Vertical distribution of modern soils and paleo-soils from red soil to brown forest soil has been made clear in the western half of this province. Although the oldest pollen sample was about 10,000yrs.B.P.pollen zones were analyzed in four sample points. In a high-mountain area and in a warm-temperate area, relation between vegetation and human impacts were found.

1992年以来，作为国际地球物理研究所（I.G.B.P.）6号研究区“古环境变化”中“亚洲季风古环境变化”的一部分，中日两国学者在中国云南省开展了这一研究项目。000年的血压，通过对裂变花粉、地貌、古土壤的分析，云南省地处热带边缘，相对高度从170米到6700米以上，三年来的研究结果表明：就目前气候而言，东北部年降水量波动显著，与厄尔尼诺现象有明显的联系。借助纬度、经度和地形因子，估计了降水和温度的回归公式。冰川的平衡海拔约为4800米。最西北部的梅里雪山和以南约300km的苍山。从红壤到棕色森林土的现代土壤和古土壤的垂直分布已在该省西半部得到明确。虽然最古老的花粉样品约为10，000年，但在四个样品点上分析了B.P.花粉带。在高山区和暖温带地区，植被与人类活动的影响之间的关系。
