Abstract: According to the QX/T 152-2012 division standard of four seasons in climate issued by the China Meteorological Administration in 2012, the authors divided climate seasons in Qingyang based on the daily average temperature data of 8 stations in Qingyang from 1981 to 2016, finding that the annual climate of this region was divided into no summer zone and four distinctive seasons zone. The results showed that: the beginning date of spring time was between the end of mid-April to the early late-April, earlier in southwestern region than that in northeastern region; the beginning date of summer time was between the end of June to late- July, earlier in northwestern region than that in south-central region; the beginning date of autumn time was between the end of mid-July to mid-August, earlier in eastern region than that in western region; the beginning date of winter time was between mid-October to early late-October, earlier in northeastern region than that in southwestern region. The authors analyzed the beginning date of each season in four distinctive seasons zone by the methods of linear correlation analysis. The results showed that the beginning date of spring and summer had an advanced trend, the beginning date of winter had a postponed trend; the duration of autumn showed an extended trend, and the duration of winter showed a shortened trend. In response to climate change, this region has adjusted the planting structure in recent years, introduced hardy and drought-resistant quinoa, expanded alfalfa cultivation, developed animal husbandry, and increased the input to facility agriculture.
