Abstract: In order to analyze change trend and abrupt change characteristics of growing season temperature, surface temperature and the maximum frozen soil depth of facility agriculture during frost season of this district based on the data of daily temperature, surface temperature and frozen soil depth from 1961 to 2012 of climate monitoring station of Jianchang County adopting modern climate statistical diagnosis technique. The results showed that: average temperature and average surface temperature of growing season of Jianchang County facility agriculture during frost season rose obviously. The inclination rate was 0.30℃/10 a, 0.29℃/10 a respectively. Air temperature rose with mutability in 1982, followed by average temperature rise of 1.2℃; surface temperature rose with mutability in 1989, followed by average temperature rise of 1.1℃; the maximum frozen soil depth became obvious shallow. The inclination rate was -4.63 cm/10 a. In 1985, it became abruptly shallow and then the maximum frozen soil depth became shallow for 18.3 cm meters on average. When the temperature increased by 1°C, the maximum depth of permafrost would decrease by 9.6 cm. Temperature rising in frost season meant increase of heat resources, which was beneficial for facility agriculture development. Frozen soil depth becoming shallow could reduce freeze injury of greenhouse plants. The study result could provide climate evidence for rapid development of solar greenhouse of facility agriculture.
