In order to enhance the understanding of the potential impact of climate change on water availability in the North of Algeria, the spatial and temporal evolutions of the De Martonne aridity index and the Pinna combinative index during the 1980–2018 period were investigated in the present study. The temporal trends in the aridity index time series were examined using the Mann–Kendall and Sen’s slope estimator tests, while the spatial interpolation of the aridity indices and their trends were conducted in a geographic information system environment using the Inverse Distance Weighting technique. The most important outcomes of this study are that the De Martonne aridity index is more appropriate for climate classification in the North of Algeria and that there were no statistically significant aridity changes in most regions during the studied period even though two regional behaviors with respect to aridity index trends were identified in the study area.

为了加深对阿尔及利亚北部气候变化对水资源可利用性的潜在影响的了解，本研究调查了1980-2018年期间马丁内德干旱指数和品纳综合指数的时空演变。使用Mann-Kendall和Sen的斜率估计检验检验了干旱指数时间序列的时间趋势，而干旱指数的空间插值及其趋势是在地理信息系统环境中使用逆距离加权技术进行的。
