摘要

The section the authors investigated, a 210 cm deep section at an elevation of 553 m at latitude 41°18’34.3″N, longitude 119°28’5.4″E, is located on the northeast part of the Chengzishan Site. The authors got a detailed record of agricultural activities and its impact on the environment in Lower Xiajiadian period through the notes of pollen, microcharcoal, charred seeds and nutshell. The record indicates that the original vegetation was coniferous forest dominated by Pinus; because of the ’slash-and-burn’ cultivation, the original forest disappeared, meanwhile, the secondary Corylus sp.shrubs and anthropogenic weeds increased. The research reveals that the agricultural activities of Lower Xiajiadian people in Chenzishan site experienced four stages: deforestation for farming, settlement and cultivation, abandonment of the cultivated land and restoration of original vegetation.
