| 英文摘要 | Pollen and charcoal particles from a Jinchuan peat (northeastern China) were examined to investigate the fire origin and interaction between climate, vegetation, fire and human activity during the Holocene. Pollen results show that: (i) a broadleaved deciduous forest was dominant during the early Holocene; (ii) from similar to 5500 cal. yr B.P. there was a gradual increase in coniferous trees (mainly Pinus), and a decrease in broadleaved deciduous trees (e.g. Quercus, Juglans, and Ulmus-Zelkova); (iii) after similar to 4200 cal. yr B.P., the deciduous forest was replaced by a mixed forest of coniferous and deciduous trees; (iv) coniferous trees including Pinus, Abies and Picea further increased after similar to 2000 cal. yr B.P., reflecting a cooler and drier climate after similar to 5500-4200 cal. yr B.P. Two layers of abundant microfossil charcoal particles (250-10 mu m) and the coexistence of inacrofossil particles (>2 mm) suggest two local fires: fire event 1 (5120 +/- 66 cal. yr B.P.) and fire event 2 (1288 +/- 8 cal. yr B.P., AD 662 +/- 8). Charcoal layer 1, with a large amount of Monolete psilate spores, is superimposed on the long-term trend of vegetation changes, indicating a natural origin for fire event I that was probably facilitated by drying environmental conditions since the mid-Holocene. Cerealia-type pollen and a low percentage of Monolete psilate spores were observed in charcoal layer 2, indicating that fire event 2 was caused by clearing. We suggest that fire event 2 may be related to the spread of the Hart farming culture accompanied by the territorial expansion of the Tang Dynasty to the studied area in AD 668.
