水旱灾害是贵州最主要的农业灾害。文章以十年为一时段,对明清贵州470年的资料统计分析,可看出明清时期贵州水旱时空分布特点是:总体上水旱灾害越来越频繁,且明末清初(1641-1670年)和清代中后期(1811-1910)是贵州水旱灾害的多发期;在空间上,水旱灾害主要集中于黔东北的印江、思南、铜仁和遵义等地区,水旱灾害具有交替出现的特点。尽管与其它省区相比,贵州的水旱灾害并不是十分突出的,但由于贵州属典型的喀斯特地貌,对水旱灾害的响应特别敏感,表现更为脆弱,从而使贵州水旱灾害呈现独特的区域特征。
Floods and droughts are the most important agricultural disaster in Guizhou. The article takes 10 years as a period of time, and analyzes the data of 470 years in Guizhou in the Ming and Qing Dynasties. It can be seen that the spatial and temporal distribution of flood and drought in Guizhou during the Ming and Qing Dynasties is characterized by floods and droughts becoming more and more frequent, - 1670) and the middle and late Qing Dynasty (1811-1910) were flood and drought disasters in Guizhou Province. In space, floods and droughts were mainly concentrated in the areas of Yinjiang, Sinan, Tongren and Zunyi in northeast Guizhou, Disasters have the characteristics of alternating. Although the flood and drought disasters in Guizhou are not very prominent compared with other provinces and autonomous regions, the typical karst landforms in Guizhou are particularly sensitive to floods and droughts and more vulnerable to floods and droughts in Guizhou, making the flood and drought disasters in Guizhou unique Regional characteristics.
