摘要
石羊河流域是研究西北干旱区人地关系的理想区域.在干旱地域中,河流对环境变迁与人类活动有着极高的敏感性.通过对收集的全新世以来石羊河流域的人类活动数据和自然资源领域数据,包括独立的人类活动记录和古环境历史记录,进行再分析.基于一系列的区域气候数据、人类活动历史、古气候模拟结果,以及详尽的环境历史资料,深入分析全新世气候变化和人类活动对石羊河流域的影响.结果表明,在全新世的早期至中期,石羊河流域的生态环境演变主要受控于区域气候的波动.然而,进入全新世晚期,随着社会生产力的发展,人类活动的影响力逐渐提高,人类活动成为主导石羊河流域环境变化的关键因素.
The Shiyang River Basin represents an ideal area for studying human-environment interactions in the arid region of northwest China,where rivers are highly susceptible to environmental changes and human activities.By re-analyzing the anthropogenic and natural data collected from the Shiyang River Basin since the Holocene,including independent anthropogenic records and palaeoenvironmental history records,we can conclude that the impacts of Holocene climate change and human activities on the Shiyang River Basin have been analyzed based on a series of regional climate data,anthropogenic histories,palaeoclimate simulation results,and detailed environmental history information.The findings demonstrate that during the initial to intermediate Holocene period,the evolution of the Shiyang River was mainly influenced by regional climate fluctuations.However,in the late Holocene,with the advancement of social productivity,the impact of human activities gradually intensified,becoming a pivotal driver of environmental change within the Shiyang River Basin.
