摘要:新疆地处亚洲中部干旱区,地形复杂,生态环境脆弱,抵御灾害的能力较低,是全球气候变暖的敏感区和强烈影响区。随着全球气候变暖,新疆的干旱化问题引起了广泛关注。本文基于中国新疆区域55个气象观测站1961–2015年逐日气温和降水观测资料,经过数据质量控制和异常值剔除,计算得到每个站点1961–2015年1、3、6、12、24和48个月时间尺度逐月标准化降水蒸散发指数(SPEI)时间变化序列,整理出新疆干旱指数数据集。本数据集为分析新疆区域长时间序列不同时间尺度干旱变化趋势及变化特征提供了数据支撑,也可以作为基础数据来探索干旱事件对生态水文环境和农牧业生产的影响。

Abstract & Keywords
Abstract:  The province of Xinjiang is located in the Eurasian hinterland in northwestern China, with the complex terrain, and fragile ecological environment. Xinjiang is particularly sensitive to global warming. With the global warming, drought over Xinjiang has caused extensive attention. Based on the daily temperature and precipitation observed at 55 meteorological stations over the Xinjiang during 1961 – 2015, this study calculated a series of drought indices based on the Standardized Precipitation Evapotranspiration Index (SPEI). The SPEI was calculated for each station with time scales of 1, 3, 6, 12, 24 and 48 months selected for analysis. This dataset is useful for research on the change trend and spatial-temporal characteristics of drought events over the Xinjiang. When used together with regional statistical data, this dataset can also reveal the impacts of drought on agricultural production and eco-hydrological environment.
Keywords: Xinjiang; Drought indices; SPEI
