摘要
集宁路元代建制,原系金代集宁县,该城池始建于金代(公元1192年),元代沿用并有所扩建.该遗址经过多次发掘,取得了一系列重大成果.本文对城内探方T024062和T056054,以及城外东南磨子河剖面孢粉样品进行了分析.孢粉组合反映了人类进驻以前遗址周围的自然植被为以堇菜科和蒿属植物为主的草原植被,当时气候温湿偏干;金代时期植被为温暖偏干环境下以蒿属植物为主的草原,先民的生产和生活方式以放牧和农耕种植相结合为主;元代时期植被仍以蒿属为主,但草原面积缩减,早期气候温暖偏干,晚期水生植物狸藻繁盛,同时蕨类植物碗蕨、膜蕨、凤尾蕨和中华卷柏出现,气候向温暖湿润转变,随着环境条件的改变,生产生活方式相应地转变为以农作物种植为主,兼有放牧、捕鱼和狩猎.
The city of Jininglu was built during the Jin Dynasty(A.D. 1192) and expanded during the Yuan Dynasty. An archaeological site excavated in ancient Jininglu recently produced a series of important findings. The present paper describes the palynological samples collected from three stratigraphic sections at this site; T024062,T056054 and Mozihe. The palynological assemblages from these sections reveal that the vegetation before human influence was grassland dominated by Violaceae and Artemisia plants in a warm and humid climate with some dry conditions. During the Jin Dynasty,the vegetation changed to grassland dominated by Artemisia and the climate became warm and dry. The people at this time practiced livestock farming and agricultural cultivation. During the Yuan Dynasty the grassland vegetation was again dominated by Artemisia; however,the grassland decreased in area. Based on vegetation analysis,the climate transitioned from warm-dry in the early stage of the Yuan Dynasty,to warm-humid in the late stages,with an increase in Lentibulariaceae along with the occurrence of Dennstaedtiaceae,Hymenophyllaceae,Pteris and Selaginella sinensis. During this period,human practices became more diverse with agricultural cultivation,livestock farming,fishing and hunting.
