目前国内外许多学者都在关心气候转暖问题。有人认为候气转暖将使极冰融化、海平面上升,沿海城市淹没;经向温度梯度减小纬向环流减弱,内陆地区降水减少,干旱频率增加,对农业生产将产生不利的影响等。本文分析了安徽省冬季气候转暖对农业生产的影响。1 安徽省逐年最低气温的变化图1是本区几个测站历年极端最低气温三年滑动平均曲线。该图清楚地显示,本区历年最低气温,在30多年中是在波动状态中缓慢上升的,特别是自1970年以后上升明显,而且北部比南部上升更显著。 At present, many scholars at home and abroad are concerned about climate warming. Some people think that the warm-up of draft will cause the melting of polar ice, rising of sea level and inundation in coastal cities; decreasing the latitudinal circulation by decreasing the temperature gradient, reducing the precipitation in inland areas and increasing the frequency of drought will have an adverse impact on agricultural production . This article analyzes the impact of winter warming in Anhui Province on agricultural production. 1 ANNUAL CHANGE OF ANNUAL TEMPERATURE IN ANHUI PROVINCE Figure 1 shows the three-year moving average curve of extreme minimum temperature over several years in several stations in this area. The chart clearly shows that the lowest temperatures in the calendar year over the past 30 years have been rising slowly in a fluctuating state over the past 30 years, especially since 1970, with a marked increase in the northern part over the south.
