摘要:

为了计算不同致灾风力对湖北省设施农业造成灾害的概率,并分析致灾风力变化特征。本研究利用湖北省1991—2020年的气象观测数据,结合灾情数据资料,用双条件约束定义了轻度、中度、重度、特重等级指标。结果表明:风速越大,设施农业致灾概率越大;四季致灾风力出现天数分布均匀,春、夏两季出现天数大于秋、冬两季;EEMD分析结果表明,湖北省设施农业致灾风力存在2~3年、6年和15年左右的准周期变化,且2008年以前一直保持稳定,2008年后表现为显著的上升趋势,未来致灾风力日数可能出现增多趋势;设施大棚风灾风险整体呈现中部地区高,东西部低的趋势,襄阳市风灾风险最大。整体来看,孝感市、恩施州、武汉市、宜昌市、黄冈市、十堰市、咸宁市处于风灾轻中度风险区,有利于设施农业发展。

Abstract:

To calculate the probability of disasters caused by different hazard winds to facility agriculture in Hubei Province, and analyze the change characteristics of disaster-causing winds, based on the meteorological datasets of each city in Hubei from 1991 to 2020, this study defined the indexes of mild, moderate, severe, and extra-heavy grade of wind disasters by double-condition constraints. The results showed that the greater the wind speed, the larger the disaster probability of facility agriculture was. The days of hazard winds were evenly distributed over the four seasons, and the days in spring and summer were greater than that in autumn and winter. The Ensemble Empirical Mode Decomposition (EEMD) analysis results showed that there were quasi-periodic changes of about 2-3 years, 6 years and 15 years in the disaster-causing wind force of facility agriculture in Hubei and the disaster-causing wind force remained stable until 2008. Since then, it showed a significant upward trend, and the number of disaster-causing wind days might increase in the future. The overall wind disaster risk in facility greenhouses was high in the central of the province and low in the east and west. The risk of wind disaster in Xiangyang was the greatest. In summary, the following cities, including Xiaogan, Enshi, Wuhan, Yichang, Huanggang, Shiyan, and Xianning, are at mild to moderate risk of wind disasters, which are suitable for the development of facility agriculture.
