摘　　要：本文利用南溪区2011~2023年的气象观测资料和油菜生产数据,分析和研究南溪区油菜籽产量与气象因子的相关关系,进而探究南溪区油菜籽产量对当地气象因子的反应。研究表明:1) 在油菜生长全阶段,南溪区油菜籽产量与平均气温、相对湿度以及累计日照时数呈正相关关系,与累计降水量呈负相关关系,相关性系数−0.1. 2) 油菜生长的各阶段时期,年际累计日照时数与平均气温与油菜籽产量相关性不强,但南溪区的气候条件能够满足油菜生长的基本需求。3) 油菜生长的各阶段时期,年际累计降水量和相对湿度与南溪区油菜籽产量相关性较强。特别是相对湿度条件,非常适合油菜的生长。由此可以得出,南溪区气象条件适宜油菜的生长,同时气象因子对油菜籽产量总体上贡献是积极的。This article analyzes and studies the correlation between rapeseed yield and meteorological factors in Nanxi District using meteorological observation data and rapeseed production data from 2011 to 2023, and further explores the response of rapeseed yield to local meteorological factors in Nanxi District. Research has shown that: 1) Throughout the entire growth stage of rapeseed, the rapeseed yield in Nanxi District is positively correlated with average temperature, relative humidity, and cumulative sunshine hours, and negatively correlated with cumulative precipitation, with a correlation coefficient of −0.1. 2) During each stage of rapeseed growth, the correlation between annual cumulative sunshine hours and average temperature with rapeseed yield is not strong, but the climate conditions in Nanxi District can meet the basic needs of rapeseed growth. 3) There is a strong correlation between the annual cumulative precipitation and relative humidity during the various stages of rapeseed growth and the rapeseed yield in Nanxi District. Especially under relative humidity conditions, it is very suitable for the growth of rapeseed. From this, it can be concluded that the meteorological conditions in Nanxi District are suitable for the growth of rapeseed, and at the same time, meteorological factors contribute positively to the overall rapeseed yield.
