摘要
距今8000～5000年以来良好的地理条件,特别是气候条件是大地湾先民能够较早创造灿烂文明的主要原因。大地湾先民通过改进生产技术、社会组织和迁移来适应环境的变化。
The agreeable geographical conditions （especially the climate conditions） from 8ka B.P. to 5kaB.P. were mostly due to prosperity of Dadiwan Neolithic culture. The ancestors in Dadiwan adjusted themselves to environmental change by improving their productive technology and social pattern and immigration.
