With the progress of study on global climate change and the sensitivity simulation of various climate systems, human activities might be one of important factors driving climate change in historical periods. Therefore, since the beginning of this century, Land Cover Change has become the currently hot topic of global change research and climate simulation. The establishment of pollen-vegetation-land use relationship may be one of the effective ways to obtain quantitative estimates of human impact on natural environment. Therefore, in the Taihang Mountains,two small watersheds were selected to detect the relationships quantitatively among pollen, vegetation and land-use of small watershed by using pollen data. There are natural vegetation components and crop pollen types in pollen assemblages, which well reflect the relationships among pollen, vegetation and land-use in small watershed. As altitude decreases, the area of farmland, the intensity of human activities and the cereal, vegetable pollen percentages increases. The regression analysis of pollen percentages and land-use indicate that a linear positive relationship exists between the percentages of cereals, vegetables pollens and the area of farmland, which has a significance for human activities.
