摘要

对意大利皮埃蒙特(Piedmont)和撒丁岛(Sardinia)两个具有不同气候特征(分别为温带大陆性气候和地中海气候)的地区进行了为期37年(1981-2017)的水文干旱趋势研究。为此，我们分析了两个地区统一设置的13个气象站的日资料，并对标准化降水指数(SPI)和标准化降水蒸散指数(SPEI)的变化趋势进行了评价。然后考虑了两个地区指标之间的异同。两区大部分台站SPI均有显著的上升和下降趋势。然而，在两个气候带中，两个指数站平均指数的变化趋势并不显著。

Hydrological drought analysis in Continental Temperate and Mediterranean environment during the period 1981-2017

A 37 year (1981-2017) study of the hydrological drought trend was conducted in two Italian regions, Piedmont and Sardinia, with different climatic features (Temperate Continental climate and Mediterranean climate, respectively). For this purpose, we have examined the daily data of 13 meteorological stations uniformly installed in the two areas, and the trends of the Standardised Precipitation Index (SPI) and Standardised Precipitation Evapotranspiration Index (SPEI) have been also evaluated. The similarities and differences between the indices of the two regions were then considered. In most stations of both zones, there is a statistically significant trend of increase in the SPI and decrease in the SPEI. Nevertheless, the trend of indices averaged over stations of the two indices is not significant in either of the two climatic zones considered.
