摘要: 该文分析了云南近50年气候生产力变化特征以及气候变化对农业生产的影响.重点对气温、降水与小麦、水稻产量形成的关系进行了研究, 结果表明12月至翌年2月的降水是小麦增减产的关键因子, ≥10 ℃的积温比降水更有利于水稻生产.同时针对制约农业增产的重要气象灾害发生时期进行诊断, 发现小春作物的主要气象灾害是1~2月的冬旱和2~4月的倒春寒, 大春作物的主要气象灾害是5月干旱和7~8月的低温冷害.

Abstract: The characteristics of Yunnan climatic productivity variation and the effects of climatic variation on agricultural production in the past 50 years are analyzed, and the relationships between temperature, precipitation and wheat, rice yields are mostly studied. The results show that the precipitation during Dec. to Feb. of the next year
