摘要
利用 1 961～ 2 0 0 1年毛乌素沙漠年平均气温、年降水量、各季平均气温、各季平均降水量和同期中国平均气温距平资料 ,分析对比了近几十年来毛乌素沙漠气温变化与同期中国气温变化 ,气温与降水之间的关系 ,及各季气温、降水的变化规律 ,揭示了全球变化背景下毛乌素沙漠气候变化的区域性特点及其暖干化趋势 ,为毛乌素沙漠的治理提供了气象上的依据。
Based on the data of the annual mean temperature, annual precipitation, each season temperature, each season precipitation in Mu us desert from 1961~2001 and the annual mean temperature in China in the same period, the temperature changes in Mu us desert and that in China, and the correlations between temperature and precipitation in this region in recent years are analyzed and compared. Results show the regional climatic characteristics and drying and warming tendency in Mu us desert in the background of global change .The climatic drying and warming in this region will be serious in the future. The outcome of this paper will offer the reference for the desert harnessing.
