摘要
根据王苏民 [4 ] 给出的青海湖深水区重力岩芯的密集采样结果 ,重建了青海湖近60 0年的水位变化 .发现水位变化与降水关系密切 ,水位的升降时段与降水的丰枯时段相对应 .60 0年来青海湖区的环境变化有
According to the high resolution sediment data reveal by a core in deep water area in Qinghai Lake, the fluctuation of lake level in the last 600 years is reconstructed. The results show that the fall of Qinghai Lake level was more than 9m in the first half of 18th century. Moreover, there is a close relationship between lake level and climatic fluctuations in century time scale. The rises and falls of lake level are more or less in line with the wet and dry stages in the last 600 years. Wavelet analysis results inidicate that the environment in Qinghai Lake has a quasi 180 year cycle during the research period.
