吉林省气候变化及其对粮食生产的影响

The climate observation data,reanalysis data,and grain/soybean yields per unit area were used to analyze and interpret the impact of climate change on grain production.The results show that Jilin Province was located in a remarkable increase area of temperature during the growing season(May-September)from 1948 in the middle latitudes of the Northern Hemisphere.The mid-west and south of Jilin Province and Liaoning Province were located in a clear linear decrease tendency area of annual precipitation,wherein a warm/dry tendency of climate change dominated,while the east of Jilin Province lay in a clear linear decrease tendency area of annual precipitation.The climate warming played an important role in continuous increase in the grain yield per unit area since the 1980's in the main grain production areas of Jilin Province,however,from the end of the 20th century to the beginning of the 21st century,the beneficial effect seemed to be not obvious any longer,the grain yield per unit area fluctuated with annual precipitation.
