牛河梁红山文化遗址所在地区古今气候差异程度分析

The degree of difference between ancient and modern climate analysis at Niuheliang Hongshan Cultural Sites Region

6000年以来,牛河梁红山文化遗址所在的辽西地区气候已经发生变迁,但古今气候的差异程度目前尚未有学者作量化研究.根据适应野生獐生存的气候条件,结合最新考古材料,采用物候历知识尝试对红山文化时期牛河梁地区的气候进行分析还原.结论认为,牛河梁地区在距今6000年前的红山文化时期较现在的气候暖湿,同一时节的平均气温与现在当地气温延迟约20天的数值相当.

Since 6000 years,the climate of western Liaoning where Niuheliang Hongshan cultural sites has changed gradually.However,the research scholars have not quantified the degree of the difference between the past and the present climate.Based on the adaptable climatic conditions of the survival of the wild roe,the author uses the knowledge of the phonological calendar to analyze and restore the climate in the Niuheliang region of Hongshan Culture period,combined with the latest archaeological material.It concludes that it was relatively warmer and more humid in the period of Hongshan culture,which was dated from 6000 years ago than now. Meanwhile,the average temperature in the same season was delayed for about twenty days compared with that now.
