Abstract: 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.;Based on the data of environmentaI muhiproxy of lake sediments from S1 Core in East Juyanhai Lake.Inner M ongolia·there were ten stages of environmental evolution recorded by lake sediments during the past 2600 years. The characteristics of climate assembleges have a feature with the process of cold wet~ warm wet(cold dry) warm dry-cold wet. Now the climate is in the period of warm dry.the future climate will be inclined to wet.The natural climate change played as important role in the process of envlronmental evolution _n the area of Juyanhai Lake during the past 2600 years.and human activities affcted the lake environment greatly only in a special period.
