| Abstract: | Employing the regression equations relating mean annual runoff to mean annual temperature and mean annual precipitation derived
with modern data, palaeorunoff values were calculated from palaeoclimatic information for three localities in the eastern
part of the North China Plain (37 – 41°N, 115 – 120°E) during the last 12 000 years. These results present a general pattern
of temporal and spatial variations of the Holocene palaeorunoff occurring in this region. The annual runoff was the highest
during 8000 – 3000 a B.P., the second high during 12 000 – 8000 a B.P., and the lowest during 3000 – 0 a B.P. Spatially the
annual runoff was the highest at the downstream area of the Luanhe River in the north, the second highest at the area around
Beijing in the middle, and the lowest at the area around Xingtai in the southwest. These results were further compared to
other palaeohydrological reconstruction achieved by other researchers or with other methods, which usually indicates the similar
trend of hydrological changes for this region.
