| 摘 要： | 就鄂西南峡谷暖区柑桔气候生态的适应性进行了分析．首先利用极值分布理论，求得峡谷暖区的极端最低气温重现期至少为25a以上；其次是借助灰色系统理论和模糊数学手段进行了柑桔气候资源的模糊综合评判．根据评判结果推之，海拔600m以下适合种植温州蜜桔等宽皮桔，400以下适合种植甜橙，热量条件特好的区域可以种植夏橙．

| Abstract: | The recurrence period of low-tempereture freeze injury in the warm gorge sectors is thought at least every 25 years by the alternative method on simplified extreme value of Gumbel distribution. Fuzzy comprehensive judgement is used by relying on grey system theory and fuzzy mathernatics. It must be pointal out that the best use should be made of the superiority of the climate in the region, and that a large-scale orange production base should be extablished so that resource superiority can be transformed into economic superiority as soon as possible. |
