英文摘要The contribution of early human activity to the increase in atmospheric CH4 content during the middle to late-Holocene is still debated. The quantitative reconstruction of past changes in land use by early rice agriculture is a key to resolving the issue, because large uncertainties still exist in current prehistoric land use estimates, owing to a lack of direct records. In this study, we used the combination of archaeological data (the area and distribution of archaeological sites) and an improved prehistoric land use model (PLUM) to determine the spatiotemporal changes in land use by rice agriculture throughout the Yangtze River Valley, China, which was the origin and centre of the development of rice cultivation. The results indicate that the area devoted to rice agriculture increased during 10-2 ka BP, and that a significant increase occurred at similar to 5 ka BP accompanied by a spatial expansion from the northern part of the valley to the entire valley. However, the rice land use area decreased slightly during 4-3 ka BP but then increased after 3 ka BP. We estimate that the CH4 emissions from the rice cultivated area in the Yangtze River Valley increased from similar to 0.001 (+/- 0.001) to similar to 1.3 (+/- 0.6) Tg/year during 10-2 ka BP, and the resulting atmospheric CH4 concentrations increased from similar to 0.004 (+/- 0.002) to similar to 4.1 (+/- 2.0) ppb, which accounted for 3 (+/- 2)-9 (+/- 5) % of the 'anomalous atmospheric CH4 increase' during 5-2 ka BP.
