以渝东地区13个烤烟主产区的气候资料,运用模糊数学隶属度函数模型对该地区烤烟气候适宜度时空变化特征进行了分析,结果表明:1)渝东烟区全生育期气候适宜度在0.50~0.63之间,其中温度隶属度最高,波动性较小,日照隶隶属度较大,波动性大,降水隶属度最小;2)各生育期气候因子隶属度中,旺长期温度隶属度最大,伸根期次之,成熟期最小;旺长期降水隶属度最大,成熟期次之,伸根期最小;伸根期日照隶属度较大,成熟期次之,旺长期最小;3)气候适宜度、日照隶属度均呈弱的增加趋势,而降水、温度隶属度呈弱下降趋势.
Based on the climatic data of 13 flue-cured tobacco main producing areas in eastern Chongqing, the spatio-temporal variations of climate suitability of flue-cured tobacco in this area were analyzed using the fuzzy mathematics membership function model. The results showed that: 1) Between 0.50 and 0.63, the temperature membership degree is the highest, the volatility is small, the sunshine subordinate degree is large, the fluctuation degree is large, and the rainfall subordinate degree is the smallest; 2) In the growth factor climate subordinate degree, The largest, the second is the rooting period, the least is the maturity stage; the largest and lowest precipitation in Wang-long period, the second is the maturity period, the smallest is in rooting stage, the second is in sub-rooting stage and the second is in maturity stage; Degree of suitability and sunshine subordinate degree showed a weak increasing trend, while precipitation and temperature subordinate degree showed a weak downward trend.
