摘要:

近几十年来,在全球变化和社会经济高速发展的影响下,全球环境问题尤为突出。其中最为严峻的问题之一是干旱的频繁发生。干旱已经成为全球性的问题,由干旱,尤其是重大干旱灾害所引起的水资源匮乏、粮食危机、生态恶化( 如荒漠化等) ,直接威胁到国家的长期粮食安全和社会稳定。针对这些问题,本文介绍了国家对干旱研究的需求和近年来在干旱研究领域的主要科技进展,提出了目前干旱研究领域存在争议的问题、以及面对国家需求应解决的关键科学问题。并对未来5 ~ 10 a该领域的发展趋势进行了简要分析。

Abstract:


In recent several decade years,under the influence of global change and rapid socioeconomic development,the problem of
global environment was distinguished. One of the outstanding problems is drought,which is happening around the world with increasing
frequency. Drought has become a global issue. Actually,drought is an inevitable recurrent climatic event and a natural disaster affecting
the greatest spatial extent. It also has far - reaching impacts on society and environment. Because of its dual characteristics in the
natural and the social fields,drought has drawn widespread attention in the geosciences research community,the government and the
society. Water scarcity,food crisis and ecological deterioration ( for example the desertification etc. ) resulted from drought,especially
the heavy drought events,menace directly the long - term food security and social stability. With consideration of the above problems,
this paper introduces the national demand for meteorological drought research and the main study progress in the field of arid meteorology.
Controversial questions in the field of arid meteorology and key scientific issues faced to the national demand are presented. And a
preliminary analysis on the trend of development in the future 5 to 10 years in the field of meteorological drought is carried out.

Key words: drought, drought index, drought monitor and early - warning, cause of drought, field of meteorological drought research
