摘要:

【目的】研究气候变化背景下右玉县降水、气温和蒸发量的变化规律，以合理利用气候资源。【方法】采用右玉县1960—2019年逐月降水量、气温、蒸发量数据，利用距平分析法、线性倾向估计法以及Mann-Kendall检验法，对该地区的降水量、气温和蒸发量进行了系统分析。【结果】右玉县降水量呈增多趋势，气温呈增高趋势，蒸发量呈减小趋势；通过Mann-Kendall突变检验法和滑动t检验确定1994年为气温序列上升突变点，降水序列未发生突变，2002年为蒸发量序列的减少突变点。【结论】研究结果可为农业灌溉、生态环境质量改善等提供科学的参考。

Abstract:

【Objective】To study the change rules of precipitation, air temperature and evaporation in Youyu County under the background of climate change, so as to rationally use climate resources and efficiently use precipitation resources.【Method】The monthly precipitation, temperature and evaporation in Youyu County from 1960 to 2019 were systematically analyzed by using anomaly analysis method, linear trend estimation method and Mann-Kendall test method. 【Result】 Precipitation increased, air temperature increased and evaporation decreased in Youyu County. According to the Mann-Kendall mutation test and the sliding T test, the year 1994 was the abrupt change point of the rising temperature series, while the year 2002 was the abrupt change point of the decreasing evaporation series.【Conclusion】The research results can provide scientific reference for agricultural irrigation, ecological environment improvement and so on.
