摘要:

为揭示淄博市农业气象灾害风险,保障粮食安全生产,根据1983—2020年淄博市农业气象灾情资料和粮食产量数据,运用趋势分析、灰色关联法和Hurst指数等方法,分析了淄博主要农业气象灾害时空分布,并对灾害发展趋势及与粮食产量的关联度进行了探讨。结果表明:(1)淄博市农业气象灾害频发,从发生频率排序依次为干旱、大风、冰雹、暴雨洪涝、台风、冷冻灾害,灾害比重年际差异大。(2)4类主要农业气象灾害受灾率均以下降趋势为主,空间分布不均:干旱灾害高青、沂源受灾最重;暴雨洪涝灾害高青最为严重;大风灾害桓台和周村受灾最为严重;冰雹灾害高青受灾最为严重。(3)受灾率未来变化趋势为反持续性上升趋势;与粮食产量关联分析显示,干旱关联度最大,大风、暴雨洪涝灾害次之。未来淄博市农业气象灾害风险严峻,干旱是影响粮食产量的主要气象灾害,应加强防治。

Abstract:

To reveal the risk of agrometeorological disasters in Zibo City and ensure food safety production, based on the agrometeorological disaster data and grain yield data of Zibo from 1983 to 2020, the temporal and spatial distribution of main agrometeorological disasters in Zibo, the development trend of disasters and the correlation degree of grain yield were analyzed by using the methods of trend analysis, grey correlation method and Hurst index. The results showed that: (1) the agrometeorological disasters occurred frequently in Zibo. The order of occurrence frequency was drought, gale, hail, flood, typhoon and freezing disaster. The proportion of disasters varied greatly from year to year. (2) The disaster rate of the four types of meteorological disasters showed a downward trend, with uneven spatial distribution: drought disaster was most serious in Gaoqing and Yiyuan; flood disaster was most serious in Gaoqing; gale disaster was most serious in Huantai and Zhoucun; hail disaster in Gaoqing was the most serious. (3) The future change trend of disaster rate was anti sustainable upward. The correlation analysis with grain output showed that drought was the most closely related, followed by gale, flood disasters. In the future, the risk of agricultural meteorological disasters in Zibo City will be severe, the main meteorological disaster affecting grain production is drought, and prevention and control should be strengthened.

Key words: Zibo area, grain yield, meteorological disasters, disaster rate, grey correlation method
