摘 要:近56年来,前郭县农业气候资源发生了显著变化,对前郭县的玉米产量产生了显著影响。研究发现,玉米的产量变化与生长季内的降水量、日照时数、积温和平均气温的相关性较好,其中,玉米产量与降水量的正相关性最高,即玉米产量越高,所需要的水分就越多;玉米产量与日照时数的负相关性最高。In the past 56 years,the agricultural climate resources in Qianguo County have changed significantly,which has had a significant impact on the corn yield in Qianguo County.It was found that the change of corn yield was well correlated with precipitation,sunshine hours,accumulated temperature and average temperature in the growing season,among them,the positive correlation between corn yield and precipitation was the highest,that was,the higher the corn yield,the more water was needed;the negative correlation between corn yield and sunshine time.
