| 摘 要： | 基于湖北省77个气象站和45个水文站长系列逐日资料,分析了湖北省年降雨量、年蒸发量、年干燥度、年径流量Cv值等空间分布规律,并以此为依据对湖北省干旱分区进行修正。通过研究各季干燥度的空间分布规律,分析各类型干旱的空间分布规律,得到各干旱分区的干旱特征,为湖北省防旱抗旱提供科学依据。

| Abstract: | Since meteorological and hydrological rules are important to guide drought division,based on long series-daily data of 77 weather stations and 45 hydrological stations,spatial distribution rules of annual rainfall,annual evaporation,annual aridity and Cv value of annual runoff are analyzed,and then drought division of the province is rectified.Through studying on spatial distribution of quarter aridity,the spatial distribution of drought types of each division is acquired. |
