Abstract In order to explore the influence of climate change on agricultural activities in Xing'an League,the characteristics of climate change during the sowing period are analyzed by using the data of April to May daily air temperature,0 cm ground temperature,5 cm ground temperature,and ≥10 ℃ active cumulative temperature in the same period from 1960 to 2020 in Xing'an League.This paper puts forward the research method,and analyzes the variation law of temperature,ground temperature of 0 cm and 5 cm in Xing'an League during planting period in detail.At the same time,the correlation analysis of 5 cm ground temperature change on maize sowing was carried out.The conclusions obtained are intended to provide a more reasonable scientific basis for the development and utilization of agricultural climate resources and the guidance of agricultural production.
