Risk Zoning of Apple Policy Based Agricultural Insurance in Northwest of Yan'an City

  • 摘要:

    为了发展陕西省延安市西北部苹果产业,提高果农收入,实现精准赔付,达到农民与保险公司双赢,采用实地调查、数理统计、随机森林回归和自然断点法对吴起县、志丹县苹果园进行政策性农业保险风险区划分。利用吴起县、志丹县2022年3—5月日最低气温及近12年冰雹日数,基于GIS划分延安市西北部苹果政策性农业保险轻重风险区。结果表明,延安市西北部果园海拔越高,日最低气温越高,冻害程度越轻。河谷地由于冷空气堆积,温度低,为高风险区,不适合种植苹果;志丹县东部为冰雹多发地,为重、中风险区。结合冻害及雹灾影响,延安市西北部苹果政策性农业保险轻风险区占50.5%,中风险地区占21.9%,重风险地区占27.6%。建议对重风险区果园进行种植结构调整,在冰雹多发区域建设防雹网和防雹人工作业点,降低灾害影响,减少冻害高风险区苹果种植面积;中风险区应加大保险政策宣传和财政投入力度,做到应保尽保,减少果农的损失,实现苹果产业的可持续发展。
