毛乌素沙地的气候对全球气候变化的响应研究

本文利用毛乌素沙地 8个气象站近 30年的气候资料 ,运用Excel分析了该区在全球气候变化背景下的气候变化特点及其时空分布特征。近 30年来毛乌素沙地气候呈现暖干化趋势 ,气温升高且其波动性增大 ,降水量减少且其稳定性增强。该区的气候变化与全球气候变化趋势基本一致 ,增温更显著 ,干旱化趋势不太明显 ,且其气温和降水量的变化存在明显的区内差异。

Research on the Response of Climate to Global Climatic Change in Mu Us Desert

Using the climate materials in the past 30 years of 8 meteorological bureaus in Mu Us Desert, Using Excel, the paper analyzed the climatic change characteristics and its space- time distributing characteristics of the area under the background of global climatic change. The climate in Mu Us Desert had warming and drying trend in the past 30 years. Its temperature rose and its fluctuation increased. Its precipitation reduced and its stability strengthened. The climatic change was basically unanimous with global climate change tendency and its warming trend was more remarkable and its drying trend was less obvious. There was obvious difference on the change of temperature and precipitation among the counties in the area.
