利用崇仁烟区1981要2011年烤烟生育期(3要7月)气温资料,分析了该区域烤烟生育期气温的空间特征和气候变化趋势,同时利用累计距平法和滑动t检验法进行突变检验。结果表明:整个生育期内移栽期气温的变异程度最大,而成熟期气温的变异系数最小。31年内崇仁烟区气温呈逐年上升的趋势,其趋势系数为0.3℃/10年。突变分析表明,崇仁烟区烤烟生育期的气温在1997年发生突变。
利用崇仁煙區1981要2011年烤煙生育期(3要7月)氣溫資料,分析瞭該區域烤煙生育期氣溫的空間特徵和氣候變化趨勢,同時利用纍計距平法和滑動t檢驗法進行突變檢驗。結果錶明:整箇生育期內移栽期氣溫的變異程度最大,而成熟期氣溫的變異繫數最小。31年內崇仁煙區氣溫呈逐年上升的趨勢,其趨勢繫數為0.3℃/10年。突變分析錶明,崇仁煙區烤煙生育期的氣溫在1997年髮生突變。

Using tobacco growth period(from March to July)temperature data of the years of 1981-2011 in Chongren,the spatial distribution and variation trend of temperature in Chongren tobacco-growing areas were analyzed.At the same time,adopted the methods of accumulative anomaly analysis and slide T detection methods. The results indicated that the extent of variation of temperature in transplanting period was the most remarkable during tobacco growth period,and variance coefficient of temperature in maturing stage was the minimum. The changes of temperature in Chongren had an increasing trend in last 31 years,with the trend-coefficient was 0.3℃per 10 years. Mutation analysis showed that the saltation of temperature at tobacco growth period in Chongren occurred in 1997.
