[Objective]The aim was to study the effect of climate change on tobacco production in Pinkdingshan. [Method]Based on the data of temperature, precipitation and extreme climate events from five reprssntative meteorological stations in Pingdingshan from 196l to 2008,the characteristics of climate change in Pingdigshan City in recent 48 vears were analyzed by means of one variant linear regression analysis.[ Reslt] In recent 48 years, annual average temperature in Pingdingshan City showed increase trend, while there was no obvious variation in annual average precipitation on the whole; due to climate warming, drought, flood, strong wind and hail occurred more frequently, and diseases and pests of tobacco appeared in large area, which affected tobacco production greatly. [ Conclusion ] The study could provide theoretical foundation for the rational utilization of climate resources and defending the effects of nature disaster on tobacco production.%[目的]研究气候变化对平顶山烟叶生产的影响.[方法]利用1961～2008年平顶山市5个气象代表站的气温、降水以及极端气候事件资料,采用一元线性回归分析法分析近48年平顶山市气候变化特征.[结果]近48年来,平顶山市年平均气温呈波动上升趋势,年平均降水量总体变化趋势不明显;气候变暖导致早涝、大风、冰雹等极端气候事件频发,烟叶病虫害的大面积发生,对烟叶生产造成较大影响.[结论]该研究为合理利用气候资源、防御自然灾害对烟叶生产的不利影响提供了理论依据.
