根据东居延海S1孔湖泊沉积柱状岩芯的多环境指标分析结果．将近2600年来湖泊沉积物记录的环境演化过程分为十个阶段．湖泊沉积记录的气候组合特点具有冷湿→暖湿（冷干）→暖干→冷湿的过程．现阶段处于暖干阶段，预测未来气候向偏湿方向变化．近2600年来自然的气候变化在居延海湖泊环境演化中居于主导地位，而人类活动只是在特定时段对湖泊环境产生较大影响．
According to the multi-environment index analysis results of sedimentary columnar cores in S1 Juyanhai Lake, East Juyanhai. The environmental evolution of lake sediments recorded in nearly 2600 years is divided into ten stages. The climate record of lake sedimentary records has the characteristics of cold and wet → warm and humid (cold dry) → warm dry → cold and wet. At this stage is in the warm-dry stage, predict the future climate changes to the wet direction. In the recent 2600 years, natural climate change dominates in the evolution of the Juyanhai lake environment, while human activities only have a greater impact on the lake environment at a specific time.
