    摘要:

    为明确气候变化对鄂西烟草气象灾害危险性的影响,基于已建立的干旱、低温冷害、连阴雨、暴雨、高温热害的危险性指标体系,利用鄂西18个国家气象站观测数据开展近60年来烟草高影响气象灾害的危险性指数分析,并进行前30 a和后30 a的对比。结果表明,从时间维度看,后30 a鄂西烟草种植区干旱、连阴雨和暴雨危险性总体有所减轻;而鄂西南干旱危险性加重,水分条件逐渐成为影响当地烟叶生产的主要因子之一。在气候变暖背景下,低温冷害和高温热害的危险性分别呈现出部分减轻和普遍加重的趋势。分区域来看,枣阳、南漳等地持续受干旱影响,低温冷害集中在高海拔地区,高温热害则分布于河谷地带。五峰、兴山是冰雹、大风的相对高发中心,需防范强对流天气带来的危害。鄂西地区由于地理位置不同,影响烟叶生产的主要气象灾害及气候变化有所差异。从综合气象灾害危险性分布来看,除巴东北部、建始北部局地外,后30 a恩施大部分地区气象灾害综合危险性等级仍在“中等”及以上,以鹤峰最为严重。

    Abstract:

    The observation data of 18 national meteorological stations in western Hubei Province were used to conduct risk index analysis of tobacco high impact meteorological disasters in recent 60 years based on the established risk index system of damages caused by drought, chilling, steady rain, rainstorm, high temperature and high heat, and make comparison between the previous and the last 30 years to identify the effects of climate changes on tobacco meteorological disaster risk in western Hubei. The results showed that the risk of drought, steady rain and rainstorm in tobacco growing areas in western Hubei Province reduced overall in the past 30 years in term of time dimension. But the risk of drought in southwestern Hubei Province increased, indicating that water condition had gradually become one of the main factors affecting local tobacco production. Under the background of climate warming, the risk of chilling and high temperature and heat damage had shown a trend of partial mitigation and general aggravation. Regionally, Zaoyang, Nanzhang and other places were continuously affected by drought. The chilling damage was concentrated in high altitude areas, while high temperature and heat damage was distributed in river valleys. Wufeng and Xingshan were relatively high incidence centers of hail and gale, so it was necessary to prevent the damage brought by severe convective weather. It could be seen that the main meteorological disasters and climate changes affecting tobacco production in western Hubei Province were different due to different geographical locations. From the distribution of comprehensive meteorological disaster risk, except the northeastern Badong and the northern part of Jianshi, the comprehensive risk level of meteorological disasters in most areas of Enshi in last 30 years was still “medium” or above, with Hefeng being the most serious.
