Temporal and Spatial Characteristics of Extreme Drought in Apple Growing Season in Hebei Province During 1981-2020
The apple planting area and output of Hebei Province are the top in the country, and the temporal and spatial variation trends and characteristics of extreme drought in Hebei Province are analyzed, in order to provide a theoretical basis for scientific irrigation in apple producing areas, and promote the development of local characteristic agriculture and the effective utilization of water resources. Based on the data of 142 ground weather stations in Hebei Province, this paper used surface wetness index and wavelet analysis to study the temporal and spatial characteristics of extreme drought in the apple growing season in Hebei Province in the past 40 years (1981-2020), including the frequency, total number of occurrences and cyclical changes of extreme drought. The results showed that: (1) in terms of time changes, the frequency of extreme drought in the apple growing season in Hebei Province had averaged 0.7-3.5 times per year in the past 40 years. The occurrence of extreme drought in each growing period of apple growing season in descending order was as follows: initial growth period (germination-flowering stage), late growth stage, fruit coloration stage, young fruit stage, and fruit expansion period. Between the decades, the 1980s were the highest, the 2000s were the lowest, and the 2010s showed a recovery trend. (2) In terms of spatial distribution, the total number of droughts in the apple growing season showed the characteristics of less in the northeast and more in the northwest and central and southern regions, and the number of extreme droughts in the southern region was higher than that in the northern region during each phenological period during the year, but the high-value areas of extreme drought occurrence in the fruit expansion period and the late growth period were concentrated in the northwest Hebei region. The variation period of extreme drought in the province was 4-8 a, 7-11 a, 16-20 a. The frequency of extreme drought showed a recovery trend in the young fruit stage and late growth stage of apples in the 2010s, which should attract attention in the production practice.

干旱是我国北方地区最为突出的环境问题。根据WCRP耦合模式输出的未来气候变化逐月资料,基于降水-蒸发力标准化干旱指数(SPEI),分析了IPCC SRES A1B、A2和B1三种情景下,2011-2050年我国北方地区干旱状况的时空变化趋势。结果表明:中国北方地区未来40 a呈现干旱化倾向,其中轻度和中度季节性干旱发生频率降低,重度和极端季节性干旱发生频率增加,增温引起的地表蒸发增加是极端干旱频发的主要原因。A1B、B1和A2情景下,2040s整个北方地区极端干旱频率增加、强度增强、影响范围明显扩大。极端干旱的增加可能给农业生产带来风险,采取有效应对措施,将有利于区域农业的可持续发展。

掌握辽宁中部农作物生长季降水量变化与干旱风险度,为辽宁中部农业产业结构调整、规避干旱风险和农业生产管理提供参考。利用沈阳区域气象中心1961—2020年的降水和气温数据,采用气候诊断分析方法,选用积分湿润指数及其干湿指数研究降水量对农作物生长季的满足程度、干旱变化特征及干旱风险程度。结果表明:1961—2020年辽宁中部农作物生长季降水量呈减少趋势,线性减少40.5 mm;降水满足度和干湿指数呈下降趋势,分别线性下降14.5%和0.13;干旱风险度呈显著上升趋势,最大干旱风险度上升17.3%,2000—2020年平均上升11.0个百分点。播种苗期中旱+大旱约3 a一次;旺长期中旱+大旱概率约20 a一次;成熟期中旱+大旱约4 a一次。研究结果为掌握降水变化状态,干旱变化特征,认知干旱的严重程度,规避干旱风险,为“三农”及粮食生产安全以及农业结构调整和防旱减灾提供参考。
