我国云南干旱研究进展

Research Progress of Drought in Yunnan Province of China

为了研究云南干旱发生规律,探究干旱发生原因,为干旱防灾减灾提供帮助。通过阅读相关资料文献,综述了云南省干旱的时空分布特征以及成因,对云南干旱的最新研究成果进行了总结。研究发现时间上云南干旱多发生在冬春季节,空间上多发生在滇中及滇西北地区;干旱的主要原因不仅与大气环流、青藏高原、海洋及地形地貌因素有关,还和桉树的引进、水污染、水利设施落后关系密切。目前,云南省干旱受自然和社会双重因素影响,还有许多未解决的问题,需要学着们做进一步的研究。

In order to study the law of drought occurrence in Yunnan province,explore the causes of drought,provide help for disaster prevention and mitigation of drought.By reading the relevant literature,the characteristics of temporal and spatial distribution of drought in Yunnan province and the causes were analyzed,the latest research results of drought in Yunnan province were summarized.The study found that the drought occurred frequently in winter and spring in Yunnan province,and occurred mostly in central Yunnan and northwest Yunnan.The main reason of the drought and the atmospheric circulation,in addition to the Tibetan Plateau,the Ocean and topography factors,also,the introduction of eucalyptus and water pollution,water conservancy facilities were closely linked.At present,the drought in Yunnan province is affected by both natural and social factors,and there are still many unsolved problems,which need further study.
