大兴安岭呼中北山洞遗址孢粉分析与环境考古初步研究

A Spore-Pollen Analysis and a Preliminary Environmental Archaeology Research of Beishandong Site in Huzhong District,Daxinganling Region

北山洞遗址是一处包含有多个时期文化堆积的洞穴遗址。通过对北山洞遗址的孢粉分析,复原了遗址周边旧石器时代晚期、新石器时代早期、新石器时代中晚期和早期鲜卑时期的植被类型和气候环境。研究结果表明,该遗址的古植被主要以灌木草原为主,但森林的分布和主要树种则不同时期有所变化。气候条件经历了剧烈的变化,由寒冷干燥变为温暖湿润,而后再次变为干凉,又逐渐转变为温暖湿润。

Beishandong Site is a cave site that has accumulated multiple periods of cultures. Based on the spore-pollen analysis of Beishandong Site, the vegetation types and the climatic environment of the Upper Paleolithic Age, the early Neolithic, the middle and late Neolithic Age, and the early Sienpi Period were rebuilt around the site. The vegetation of this site was mainly bushveld, but the distribution of forests and major tree species varied at different times. The climate of the site had undergone drastic changes from being cold and arid to being warm and humid, then became dry and cool, and finally warm and humid.
