摘要：

为预测未来气候变化对烤烟产量的影响趋势,借助作物生长模型,结合《排放情景特别报告》(Special Report on Emissions Scenarios,SRES)的2种排放情景A2（强调经济发展）和B2（强调可持续发展）预估的未来气候情景,定量地模拟分析了重庆地区烤烟种植对气候变化的响应与适应。结果表明,种植当前烤烟品种,到2020年,A2情景下,各地烤烟单产波动范围-4.7%~5.7%,增减产幅度不大。巫山、黔江、酉阳、南川等烤烟区仍以轻微增产为主,其余烤烟区为轻度减产区;B2情景下,各地烤烟单产波动范围-35.3%~8.1%,巫山、巫溪、黔江、南川大部等烤烟区以轻微增产为主,其余烤烟区为减产区,其中奉节、武隆烤烟区减产幅度较大,在15%以上。到2040年,A2情景下,各地烤烟区产量波动范围-15.85%~1.93%,除万州烟区轻微增产外,其余烤烟区均为减产区,其中酉阳中部、武隆南部减产幅度较大,在10%以上;B2情景下,各地烤烟区波动范围-14.45%~8.18%,其中,酉阳、彭水与黔江南部为增产区,其余地区烤烟均为减产区。无论是A2情景还是B2情景,重庆大部烤烟区可能会出现不同幅度的减产趋势,且局部减产幅度较大。如果引入适应气候变暖的新品种（模型中只延长烤烟生育后期即开花到顶叶成熟的积温）,A2情景下增产105~170 kg/hm2,增幅6.9%~10.6%;B2情景下增产40~78 kg/hm2,增幅2.5%~5.12%。受气候变暖的影响,由于积温的增加,未来10年内重庆大部地区烤烟会出现不同程度的减产,局地减产严重。如果提前移栽期,通过一些适应对策,如引入适应气候变暖的新品种,可达到很好的增产效果。

Abstract:

The paper aims to forecast the impact of future climate change on the yields of tobacco. Based on the crop growth model, and combined with the climate change scenario A2 (concentration on the economic development) and B2 (concentration on the sustainable development) of SRES, the response and adaption of flue-cured tobacco planting in Chongqing to climate change are quantitatively simulated. The results show that: the flue-cured tobacco yield will change from -4.7% to 5.7% in 2020 under the A2 scenario with current varieties, with little increase and decrease. There will be a slight increase of flue-cured tobacco yield in Wushan, Qianjiang, Youyang, Nanchuan etc. and a slight decrease in the other regions. Under the B2 scenario, the flue-cured tobacco yield will change from -35.3% to 8.1% in 2020. There will be a slight increase in tobacco growing areas of Wushan, Wuxi, Qianjiang, most parts of Nanchuan and so on, but the other regions will have a diminished output, and Fengjie and Wulong will have a yield decrease above 15%. In 2040, the flue-cured tobacco yield will change from -15.85% to 1.93% under A2 scenario, except for a slight increase in Wanzhou tobacco growing areas, the yield of the rest areas will reduce, and the central part of Youyang and southern Wulong will have a higher reduction rate over 10%. Under the B2 scenario, the flue-cured tobacco yield will change from -14.45% to 8.18%, Youyang, Pengshui and southern Qianjiang will have a yield increase, and the rest areas will have a yield reduction. Either under A2 scenario or B2 scenario, most tobacco growing areas of Chongqing will show different reduction trends, some areas will have a higher reduction rate. If new varieties adapting to climate warming could be introduced in Chongqing (only prolonging the accumulated temperature of the late growth of flue-cured tobacco in the model from flowering to parietal maturity), under the A2 scenario, the flue-cured tobacco yield will increase by 105-170 kg/hm2, with an increase rate of 6.9%-10.6%, under the B2 scenario, the flue-cured tobacco yield will increase by 40-78 kg/hm2, with an increase rate of 2.5%-5.12%.
