中文摘要:
      气象灾害影响春播期农业生产,监测青海主要农作物气象灾害并对其进行预估对作物生长至关重要。基于气象观测,利用归一化法、克里金插值法和层次分析模型,综合评价了青海省春播期气候特征、主要气象灾害影响区域及农作物生长情况。青海省春播期主要集中在3月中下旬—5月上旬,青稞在3月易遭受冻害,春小麦、油菜、豆类在4月上中旬易遭受冻害,玉米、马铃薯、蕨麻在4月下旬易遭受冻害。受极端气候事件影响,河湟和祁连山地区易发生旱灾,西宁市、果洛州、海北州、海南州、黄南州易发生涝灾。2021年春播期,青海省气温总体偏高,降水呈“北少南多”的趋势,春播期小麦、马铃薯、油菜、蕨麻种植区主要受干旱和冻害影响,易发生在4月,建议推迟播种、及时灌溉;青稞种植区主要受冻害或暴雨洪涝影响,冻害和暴雨洪涝分别发生3月和5月,建议关注土壤墒情、做好农田排水。青海省春播期主要气象灾害影响预估有助于有关部门及早分析研判、部署,做好播种和出苗关键期的气象保障工作。
英文摘要:
      Meteorological disasters significantly impact agricultural production during the spring sowing period, making the monitoring and prediction of such disasters for major crops in Qinghai crucial for crop growth. Based on meteorological observations, this study comprehensively analyzes the climate characteristics, major meteorological disaster\|prone areas, and crop growth in Qinghai province during the spring sowing period using normalization methods, a hierarchical analysis model, and kriging interpolation. The findings indicate that the spring sowing period in Qinghai province primarily occurs from mid\|to\|late March to early May. Barley sown in March is highly susceptible to frost damage, while spring wheat, oilseed rape, and beans planted in early to mid\|April are also vulnerable to frost. Additionally, maize, potatoes, and ferns sown in late April face a high risk of frost damage. The Hehuang and Qilianshan regions are prone to drought due to extreme weather events, while Xining, Guoluo, Haibei, Hainan, and Huangnan are more susceptible to flooding. During the 2021 spring sowing period in Qinghai province, overall temperatures were high, and precipitation followed a “less in the north and south” trend. The cultivation of wheat, potatoes, oilseed rape, and ferns was primarily affected by drought and frost damage. These adverse conditions, most likely to occur in April, necessitate delaying sowing and ensuring timely irrigation. Barley\|growing areas, on the other hand, were mainly impacted by freezing temperatures, torrential rainfall, and flooding. These events occurred in March and May, respectively, making it essential to monitor soil moisture and implement effective farmland drainage measures. The meteorological disaster impact forecast for Qinghai province’s spring sowing period provides a crucial basis for early analysis, research, and planning. It supports key agricultural activities, ensuring effective meteorological protection during sowing and seeding periods for the relevant departments.
