摘要
沉积物柱芯采自贵州威宁草海深水湖区。不同深度沉积物中粘土矿物及其它特征表明在过去几千年时期内 ,草海区域的气候经历了热湿向暖干的激烈变化。同时 。
The sedimentary core was taken from the deep-water location in Caohai Lake of Weining, Guizhou province. Clay minerals and other features of the sediment in different depth show that the climate of Caohai region changed from hot-humit to warm dry in the past several thousand years. In addition. Caohai varies to closed lake from open state.
