摘　　要：Quantitative studies on the climatic ecology of Citrus L. are carried out in the warm gorge sectors in southwestern Hubei Province.The recurrence period of low-temperature freezing injury in the regions is estimated as at least every 25 year by the alternative method on simplified extreme value of Gumbel distribution.Fuzzy comprehensive judgement is used based on gray system theory and fuzzy mathematics.The paper points out that the superiority of the climate should be used effectively in the regions,and that a large-scale Citrus L. production base should be established,so that resource superiority can be transformed into economic superiority as soon as possible.Quantitative studies on the climatic ecology of Citrus L. are carried out in the warm gorge sectors in southwestern Hubei Province.The recurrence period of low-temperature freezing injury in the regions is estimated as at least every 25 year by the alternative method on simplified extreme value of Gumbel distribution.Fuzzy comprehensive judgement is used based on gray system theory and fuzzy mathematics.The paper points out that the superiority of the climate should be used effectively in the regions,and that a large-scale Citrus L. production base should be established,so that resource superiority can be transformed into economic superiority as soon as possible.
