摘要: 以黄河源区气象台站的降水和气温资料以及玛多、达日、玛曲、唐乃亥和兰州水文站的径流资料为基础, 分析研究了该区降水、气温、水文变化趋势, 并对研究区的土地利用现状变化及原因进行了探讨. 结果表明: 在年代际变化趋势上, 黄河源区气温总体上呈升温态势, 降水呈减少趋势, 径流量也表现为减少趋势.土地利用现状的变化表明人类活动对研究区生态湿地的干预增强.自然因素和人类活动的综合作用, 使得黄河源区生态环境进一步恶化, 亟需进行人工干预, 保护和改善黄河源区生态湿地环境.

Abstract: Based on the data of precipitation and air temperature from weather stations in the source regions of the Yellow River and data of runoff from Madoi, Darlag, Maqu, Tangnag and Lanzhou hydrologic stations, the changes of precipitation, air temperature and runoff during the past several decades are investigated. Meanwhile, changes in land use patterns and their reasons in these regions are studied. It is revealed that an obvious increase in air temperature and decrease in precipitation and runoff in these regions. Changes in land use indicate that the wetland is affected by human activity and climate change. The change is resulted from the combinations of nature factors and human activity. Thus the eco-environment in the source regions of the Yellow River will deteriorate further. Artificial intervention is needed to protect and to improve the eco-environment in the source regions of the Yellow River.

Key words: source regions of the Yellow River, eco-environment, hydrology and water resources, climate change
