摘要:
通过对黑河下游天鹅湖-2孔湖泊沉积柱状岩芯的多环境指标的分析,同时参照相关的历史文献记录,提取了其中包含的气候变化和人类活动信息.根据天鹅湖-2孔湖泊沉积记录,将天鹅湖在近200年的湖泊演化分为七个阶段,影响湖泊演化各个阶段的主导因素各不相同,包括气候变化与人类活动,正是这两者的共同作用导致了天鹅湖及其周围地区的环境变化.湖泊沉积记录的环境演化主要受气候冷暖干湿变化的控制,而人类活动在特定时段对湖泊环境演变产生明显影响.

Abstract:
Based on the data of environmental multi-proxy of lake sediments from Core 2 in Lake Swan, one of the tail-lakes of Heihe River, the contained information of climate changes and human activities is distilled. The evolution of Lake Swan during recent 200 years is divided into 7 phases according to the information recorded by lake sediment. In each phases different factors affected the lake evolution on different levels, and the combining effect of both climate changes and human activities led evolution of Lake Swan and the environmenta changes of Ejina Oasis. The natural climate change played a leading role in the process of evolvement of Lake Swan during recent 200 years, and human activities affected the lake environment greatly especially in special periods.
Key words:  Lake Swan  lake sediment  climate changes  human activities
