Abstract

In monsoon area of eastern Asia, the interstadial of the Last Glacial, that is M IS3a or 40-22 kaBP, was a warm and wet stage. There was probably more precipitation at this interval than the present in South-east Monsoon are-a. In the Tibetan plateau there were more precipitation during 40-22 kaBP than the MegathermalMaximum in the Hol-ocene reconstructed with hydrological and energy balance of closed lake basin. Evidence from gravel-sand bars around lakes shows that HuangqihaiLake have experienced high-level stage during 40-22 kaBP. These gravel-sand bars are mainly found at the foot of mountain, Libaisi northern hill and Gu hill,such as. At the Libaisi northern hill, the sand-bar, with a. s. l 1310-1318 m, covered by stripe-like meadow, was dated 24.43～2.33 ka BP by OSL method. This paper calculated palaeo-precip itation of this stage in Huangqihai basin, in order to analyze the difference of precipitation in the monsoon area of eastern Asia and the Tibetan plateau. Based on the modern relief map, if the high lake level stand on the 1310-1318 m, 50 m higher than the present, Huangqihai Paleolake had an area of 450～515 km² ( average 466 km²), 4.4-5.1 times of that of the present (1950-1961A. D). Using J. E. Kutzbach's equation of energy balance to compute the land evaporation and water surface evaporation with step-after-step app roachingmethod to obtain the parameters, we modeled the combined hydrological and energy balance of Huangqihai basin, and the following estimates of precip itation were yielded: 479-497mm / a during 40-22 ka BP, higher 126-144 mm / a than the present. But we do not think the precipitation is more than that of the highest lake level stage in Holocene. The p recip itation, however, in the Tibetan Plateau, was higher at 40-24 kaBP than at 1424.0 ka BP. Certainly, the reestablished palaeo-precipitation, is only when the high lake level stand at a. s. l 1310-1318 m during some stage of 40-22 ka BP, not that of stage of 40-22 ka BP when lake level was lower than 1310-1318 m.
