Abstract: In order to overall analyze the change characteristics of agroclimatic resources in Jingyuan County under the background of climatic warming, providing scientific reference for reasonably utilizing climatic resources and agricultural production. The author used the observation data, including temperature, rainfall and sunlight hours over the recent 60 years and the statistical methods of linear-trend analysis, Mann-Kendall and power spectrum, the long-term changes in agroclimatic resources in Jingyuan County were analyzed. The results showed that: (1) in the context of global warming, the heat resources of Jingyuan County significantly increased tendency of the annual average temperature change rate of 0.17°C/10 a, there were 9 a and 4 a significant periods and mutations of warming in 1994. The active accumulated temperature for daily mean temperature steadily through 0℃ and 10℃ showed increasing trends, with rates of 25.5 ℃.d/10 a and 34.3 ℃.d/10 a, respectively. (2) The annual precipitation of Jingyuan County showed a trend of weak reduction and change tendency rate was -5.3 mm/10 a, the precipitation mainly concentrated in the summer, with a large inter-annual change, and prone to droughts and flood disasters. Changes in precipitation showed 7.6 a and 3 a significant periods. (3) The annual amount sunshine duration was 2706.4 h in Jingyuan County, with regard to summer crop growing season (April to July) and autumn crop growing season (May to September), the total sunshine duration are about 1010 h and 1233.6 h, respectively. The annual amount sunshine duration transformed reduction into increase from the 1970s and showed 4.5 a significant changes periods.
