作为我国气候变化最为敏感地区之一的西辽河流域,新石器时代考古学文化面貌复杂多变,文化格局亦不稳定,“文化一统”到“多种文化并立共存”交替发展。农业经济起源较早,且因环境改变而逐渐占据主体地位。为了追求食物资源最大富集地,迁移成为人类适应自然环境的一种常见的方式。迁移的频率与聚落使用时间的长短也因环境的变化而变化。
As one of the most sensitive parts of China’s climate change in the Xiliaohe River Basin, the Neolithic archeology has a complex and varied cultural landscape, and its cultural pattern is not stable. The “cultural unification” and the “multi-cultural coexistence” alternate. The agricultural economy originated earlier, and gradually assumed the dominant position due to environmental changes. In pursuit of the largest enrichment of food resources, migration has become a common way for humans to adapt to the natural environment. The frequency of relocation and the length of use of settlements also vary due to changes in the environment.
