Examples
- ( 4 ) 5000 - 3100ab . r , through comprehensive analysis of these proxy climatic substitute indexes indicates : this was another warmth and humidity period in which the temperature risen and the precipitation decreased , but the warmth and humidity were not as proper as those in the best period mentioned above ; the forest vegetation may recovered ; there were flood sediments in the dust in the early - middle stage of the period ; in the early stage was longshan culture , and in the early - middle stage the human culture developed and it entered into period of xiashang civilization
（ 4 ） 5000 3100ab p ，综合多气候代用指标的分析结果表明：本期气候表现为温度升高、降水增大的变化，但温湿程度总体上不如前面的最适宜期；植被可能恢复到森林景观；在早中期粉尘沉积过程中有洪流沉积。早期为本区的龙山文化期；期间的洪水事件可能进一步强化了人地关系，并进而推动了本区人类文化的发展而进入夏商人类文明时期。 - The thesis draws the following conclusion : ( 1 ) 11500 - 8500ab . p . , through comprehensive analysis of these proxy climatic substitute indexes reveals : this was a period in which the temperature risen and the precipitation increased , but it was mainly still dry and cold ; the vegetation was prairie or forest prairie ; there were flood deposits in the dust sediments of late stage ; and it was the shifting period from the new stone age to the old stone age
主要得到以下几方面的认识： ( 1 ) 11500 8500ab . p . ,综合多气候代用指标分析的结果表明：本期气候表现为温度升高、降水增大的好转时期，但总体上仍以干冷为主；结合很少发现较粗颗粒木炭屑的情况推断当时的植被是草原或森林草原；研究发现在后期粉尘沉积过程中有洪流沉积。
