中文摘要	干旱区生态环境极其脆弱,对气候响应极其敏感,继续开展该区域气候及其影响机制研究,对于更深入地认识干旱区气候成因,进而更好地做出干旱区气候预测具有重要的科学意义。从干旱区划分、干旱区气候成因及其变化等几个方面归纳和总结了近几十年来国内外部分研究进展:目前较准确的干旱区划分方法是干旱指数法,可将全球划分为八大干旱区;干旱区气候形成是多个因素共同影响的结果,共有Hadley环流、大地形、陆气相互作用、沙尘气溶胶、海气相互作用、全球变暖等六大类影响因素;各大干旱区干湿差异明显,北非、中蒙等干旱区干旱化趋势严重,而美国中西部干旱区呈湿润化趋势。目前仍存在一些亟待解决的科学问题:各干旱区对全球增温的响应差异性较大,干旱区气候预测既是重点又是难点;青藏高原隆升对中蒙旱区影响巨大,目前这方面的数值模式分辨率不够高,边界条件不够精确,需进一步完善;各干旱区气候成因及其不同干湿变化趋势的原因,目前没有公认的定论,尚不能定量区分各影响因素对干旱区气候演变过程中的相对贡献及其响应过程。
英文摘要	The ecological environment in arid areas is extremely fragile and especially sensitive to climate response. Continuous research on the climate and its impact mechanism in the arid zones is of great scientific significance for deeper understanding of the cause of climatic formation and better prediction of climate in arid regions. Some research progresses in recent decades both at home and abroad have been overviewed,including the distribution of arid areas,the causes of arid area climatic formation and arid area climate change. Studies have shown that AI index is an effective criterion for dividing arid areas. There are 8 major arid areas in the world;climatic formation in arid areas is the result of multiple factors;there are 6 kinds of influencing factors, such as Hadley Cell,land-air interaction and so on;the unlikely trend between dry and wet is obvious in arid areas,and some regions are facing more severe drought trends such as North Africa and China-Mongolia,while others show a trend of wetting such as the Midwest of the United States. At present,there are still some scientific problems to be solved urgently:The response of various arid regions to global warming is quite different,and climate prediction in these zones is both important and difficult;the uplift of the Qinghai-Tibet Plateau has a tremendous impact on the arid area of China-Mongolia,but the models of this field are not perfect enough;there are no accepted conclusions about the causes of climatic formation in different arid regions and the causes of their different wet and dry trends. At present, it is still impossible to quantitatively distinguish the relative contributions of various influencing factors in the climate evolution of drylands and their response processes.
