摘要
通过收集大同市2000-2012年的气象数据及同期农业数据,采用趋势分析法等对气候的年季变化对农作物亩产量的影响进行分析。结果表明:降水量变化与农作物亩产量变化关系较为密切,降水量的多少是影响农作物产量的主要因素。
By collecting the meteorological data of Datong City between 2000 and 2012 and the agricultural data in the same period,this paper has analyzed the influences on the crop yield per mu exerted by the inter-annual variation of climate by means of trend analysis method. Results show that： the variation of precipitation is closely related with the variation of crop yield per mu. The amount of precipitation is a major factor that influences the crop yield.
