Abstract:Based on the meteorological data from 17 stations of Shijiazhuang from 1960 to 2012,〓by using methods of the trend analysis, MannKendall test, and Morlet wavelet analysis, the variation characteristics of agricultural climate resources of temperature being ≥10 ℃ are analyzed. The results show that in recent 53 years, the beginning date with the temperature being ≥10 ℃ stably advanced at a trend rate of 1.4 days per 10 years; the ending date lagged at a trend rate of 1.1 days per 10 years; the durations were extended at a trend rate of 2.5 days per 10 years; the increased trend rate of accumulated temperature was 64.5 ℃·d per 10 years; precipitation change was not obvious, and the sunshine durations decreased obviously at a trend rate of 53.4 hours per 10 years. All the meteorological elements had sudden changes but precipitation. The changes of ending date, durations, accumulated temperature. and sunshine durations are relatively obvious. The ending date lagged obviously in 2007; the durations increased obviously after 1998; the accumulated temperature increased obviously after 2000; sunshine durations decreased obviously after 1993. The Morlet wavelet analysis of the meteorological elements indicates that there existed periodic changes in the recent 53 years. The beginning date and accumulated temperature had 2 to 4year quasiperiodic oscillation; the ending date had 2 to 3year periodic oscillation; the durations had 2year quasiperiodic oscillation; the precipitation had 3year quasiperiodic and 3 to 7year quasiperiodic oscillations; sunshine durations had 2 to 3year quasiperiodic oscillation. The changes of agricultural climate resources of temperature being ≥10 ℃ in Shijiazhuang made the crop growth earlier and the growth cycle shorter. The reduced sunshine duration had negative impacts on crops.
