分析朝阳地区多种气象因子对当地大枣产量的影响，以为做好农业气象服务工作提供参考。运用气候统计学方法和回归分析法，对朝阳市1981-2005年20年间的大枣产量和气象观测资料做回归分析，结果表明：大枣产量与5-8月降雨量、6月平均相对湿度、年日照时数、1月最低气温和6月平均气温都具有明显的相关性。当5-8月降雨量≥300 mm、6月平均相对湿度≥60%、4-9月日照时数≥1450 h、1月最低气温≥-30℃、6月平均气温≥20℃时，若无病虫害、人为等因素影响，大枣产量较高。可见从抽芽到果实成熟直至休眠期，适宜的气象条件在每一个环节中都至关重要。

This paper analyzed the effects of meteorological factors on the local jujube production,in order to provide reference for agricultural meteorological service.Using climate statistical methods and regression analysis,the relevance between the Chaoyang jujube yield during 20 years(1981-2005)and meteorological observation data were analyzed.The results showed that there was significant correlation between jujube yeild and rainfall from May to August,the average relative humidity,sunshine hours,lowest temperature in January and average temperature in June if rainfall from May to August more than 300 mm,June average relative humidity greater than 60%,sunshine time from April to September more than 1 450 h,January minimum temperature above-30℃,average temperature on June above 20℃,no plant diseases and insect pests,the impact of factors such as human,jujube yield is higher.It is suggested that from shoot forth to the fruit is mature until the rest period,the suitable meteorological conditions in every link were very important.
