摘要： 本文应用湖泊水份能量平衡方法,计算了岱海流域盆地距今8000-5100年前的古降雨量.计算结果表明当时的降雨量值比现代至少高188mm/年.

Abstract: In 1980s A. M. Swain, J. E. Kutzbach and S. Hasternrath have developed a techinique estimated paleo－precipitation based on lake-level data. In this paper we make a introduction of the techinique to Chinese researchers and use it estimating precipitation in the period 8000-5100Yr BPin the Daihai Lake basin. The calculation result shows that the annual precipitation was at least 43 per cent（ +188 mm ）higher in that period than today in the Daihai Lake region.
