摘要: 运用建立的冬小麦气候适宜度模型对全生育期气候适宜度年际变化进行了计算。结果表明,降水适宜度波动最强;温度适宜度与气候适宜度波动均较小,且20世纪80年代以来振幅明显变小。从变化倾向来看,温度、光照和气候适宜度分别以每10年0.003、0.005和0.006的速度升高,降水适宜度以每10年0.002的速率降低。

Abstract: Employing the climate suitability degree model,the annual climate suitability change was calculated.The results showed that the fluctuation of precipitation suitability was very strong while that of temperature and sunbeam is less strong,and their vibrating amplitude has become weaker and weaker since 1980s.In terms of the change trend,temperature,sunbeam and climate suitability degree in turn increased at the speed of 0.003/10yr,0.005/10yr and 0.006/10yr,while precipitation suitability degree decreased at the speed of 0.002/10yr.
