The climatic characteristics,the temporal-spatial distribution and impacts of major agro-meteorological disasters,and the main problems in the building of an agricultural disaster prevention and mitigation system in Hunan were analyzed.The results showed that agro-meteorological disasters occurred frequently in Hunan.Rainstorm floods and seasonal droughts posed the most serious hazards to agricultural production,followed by low-temperature(freezing)hazards and high-temperature hazards.The current agricultural disaster prevention and mitigation system in Hunan suffers from weak infrastructure,low-level intelligent monitoring and warning,poor emergency response guarantee,unsound disaster prevention and mitigation mechanism,and insufficient application of agricultural disaster prevention technologies.In view of these problems,this article puts forward the suggestions of establishing a comprehensive and long-term engineering defense system,a precise and effective monitoring and warning system,a smooth and efficient emergency response system,a diversified and multi-product agricultural insurance system,a stress-tolerant agricultural production system,and a joint management system.
