我院洪旱灾害研究团队在干旱研究领域取得新进展

2024-09-06  阅读:776 

受全球变化的影响,洪旱灾害受到广泛关注,包括云南在内的中国西南地区是全球干旱灾害频发区域,干旱机理、识别方法、评价模式等是其研究的重点。水利学院余航讲师、王龙教授以中国西南地区为研究区,首先从干旱机理出发,建立了区域和全球的干旱指标(文章12),从多时空尺度上解决了干旱识别率不高的问题,促进了干旱的深入认识;其次提出了一种新的序列内部结构检测的非参数统计方法(文章3),该方法不仅能够检测序列整体趋势,更能挖掘序列内部的模式特征;最后基于建立的方法,揭示了研究区干旱的地理分布规律(文章45),成果能够为研究区抗旱减灾、水资源配置提供决策参考。

上述工作得到了云南省科技厅的云南省农业节水工程技术研究中心、云南省基础研究计划等项目的资助。发表文章如下:
