摘要
采用和田市1964-2003年实际出现的初、终霜(地面0cm最低温度≤-1℃,最低气温<4℃)及无霜期的时间序列,初步分析了变化趋势,5年滑动变化、分布频率及累计距平。结果表明:初霜期推迟、终霜期提前、无霜期增长的趋势,而这种变化趋势与气候变暖理论相一致。
Based on the time series date with actual emergence of first frost , last frost (Lowest ground temperature ≤- 1℃, simultaneously lowest air temperature < 4℃), and frost - free period from 1963 to 2003, their variance tendency, 5 years glide variety, distribution frequency, and accumulated anomaly were preliminarily analyzed. Result indicated: first frost came to a later date, last frost came to an earlier date, and the frost - free period extended. This tendency was consistent with global warming.
