摘要

全球、区域和地方尺度的气候变化是21世纪研究表明的最大问题之一。巴尔干半岛,特别是保加利亚的一些主要气候变化与气温上升和降水减少有关,从而导致干旱和气候干旱。本研究的重点是对保加利亚南部非山区的气候干旱进行调查,以便在时间和空间尺度上评估干旱状况。主要调查期为1961 ~ 2015年,参考期为1961 ~ 1990年和1986 ~ 2015年。利用8个气象站逐月气温和降水资料,通过计算De marton干旱指数和Emberger干旱指数对旱情进行了分析。调查显示,保加利亚南部所有经分析的气象站都有显示半干旱或干旱气候特征的时期。保加利亚西南部(Sandanski站)和色雷斯低地西部(Plovdiv站)的干旱表现得很好。尽管研究区已形成干旱条件,但De Martonne指数和Emberger指数的多年变率趋势显示,近30年(1986-2015年)研究期干旱程度呈下降趋势。

Climate aridity in southern Bulgaria for the period 1961-2015
The climate change on a global, regional and local scale is one of the largest problems indicated by the 21st century studies. Some of the major climate changes on the Balkan Peninsula, and in particular in Bulgaria, are related to rising temperatures and decreasing precipitation, which leads to drought and climate aridity. The present study focuses on the investigation of the climate aridity in the non-mountainous part of Southern Bulgaria in order to assess the aridity condition in temporal and spatial scale. The main investigated period is 1961-2015 and the reference periods are 1961-1990 and 1986-2015. The aridity is analysed on the basis of monthly data for air temperatures and precipitation from eight meteorological stations by calculation of De Martonne aridity index and Emberger Index. The survey shows that in all the analysed meteorological stations in Southern Bulgaria there are periods which display characteristics of the semiarid or arid climate. The aridity is well-expressed in the southwest part of Bulgaria (station Sandanski) and the western part of the Thracian lowland (station Plovdiv). Despite the aridity conditions established in the investigated region the tendencies in multiannual variability of De Martonne and Emberger indices show decreasing of aridity during the last 30 years (1986-2015) of the investigated period.
