对山西吉县柿子滩遗址进行的年代测定和孢粉分析结果表明，该遗址所在的黄河中游地区，在 ３５～９．４ ｋａＢＰ期间始终是草原环境．其中 ３５．ｌ～１７．０ ｋａＢＰ属末次冰期，气候寒冷干燥，为荒漠草原环境， 晚期出现寒冷较阴湿的草原环境；１７．０～１１．９ｋａＢＰ属末次冰消期早－中期，以温和干燥的草原植被与温和 半干燥的、生长有少量落叶阔叶树的草原植被多次交替为特征；１１．９～１０．５ ｋａＢＰ再次出现寒冷干燥的冰 期气候，为荒漠草原环境；１０．５～９．４ ｋａＢＰ气候温和半干旱，并向温暖湿润方向发展，前期为草原环境， 后期过渡为生长有较多落叶阔叶树的草原环境．细石器作为新旧石器文化过渡时期的标志，主要分布 在１７．０～１１．９ ｋａＢＰ，末次冰消期早－中期相对温暖干燥且多变的草原环境有助于细石器文化的出现和发展．
The chronological and sporopollen analysis of the persimmon beach in Jixian County, Shanxi Province shows that the area in the middle reaches of the Yellow River where the site is located is always in the grassland environment during the period of 35 to 9.4 kaBP. 35 of them. L ~ 17.0 kaBP belongs to the last glacial period, the climate is cold and dry, the desert steppe environment, the late appear cold and wet grassland environment; 17.0 ~ 11.9kaBP is the last ice period early - mid-term, with mild dry grassland The vegetation was alternated with warm and semi-dry grassland vegetation with a few deciduous broad-leaved trees. The cold and dry glacial climate occurred again from 11.9 to 10.5 kaBP, The climate is mild and semi-arid, and warm and humid direction, the early stage of the grassland environment, the late transition to grow more deciduous broad-leaved grassland environment. As the symbol of transitional period of Neolithic stone culture, fine stone was mainly distributed in 17.0 ~ 11.9 kaBP, and the environment of warm, dry and changeable grassland in early, middle, late transitional period was conducive to the appearance and development of fine stone culture.
