本文依据沉积物的颜色、粒度、层理、岩性组合等特征，并参照磁性地层、磁化率、碳酸盐含量、总有机碳及碳氮比值等环境指标，初步建立云南鹤庆盆地约６００ｋａＢＰ以来的古环境演化历史。研究表明，在大阶段上环境变化存在着两次明显的转型，这可能是与构造运动驱动有关。在剖面４．１ｍ处，约１４．２ｋａＢＰ，湖盆被河流切开，导致环境指标突变。 Based on the characteristics of sediment, such as color, grain size, bedding and lithology, and according to the environmental indicators such as magnetic strata, magnetic susceptibility, carbonate content, total organic carbon and carbon to nitrogen ratio, this paper initially established about 600 kaBP Since the ancient evolution of the environment history. The research shows that there are two obvious transitions in the environment at large stage, which may be related to the tectonic movement. At 4.1 m section, about 14.2 ka BP, the lake basin was cut by the river, resulting in a sudden change in environmental indicators.
