Newly discovered pots in Inner Mongolia and Northern Hebei was detailedly measured and analysed. Based on the correlative research materials, we believe that pots of these areas are not formed by the glaciation but by weathering erosion. Their development is controlled by many factors such as wind, temperature, precipitation, moisture, vegetation, landform and rock structure, etc. Weathering, especially chemical weathering such as salt weathering, has an important implication to their form. Wind not only can facilitate weathering and erosion, but also can carry weathering products out. Based on many scientist researches about pots and our own analyses, the pots can be divided into three different types according their forming cause. Their causes reflect the special environment background. In these areas, ancient culture developed very well. Pots are in the relatively stable stage in the period of Xiajiadian Culture. There exist good responsive relationship among climatic environment, geographic processes and cultural types. This study has an important implication to the regional and global plaeoclimate reconstruction.
