THE ANLYSIS OF CLIMATIC ECOLOGICAL ADAPTABILIT OF ORANGES IN THE WARM GORGE SECTORS IN THE SOUTHWEST OF HUBEI PROVINCE

Luo Hong; Yang Zhifeng (Institute of Environmental Sciences, Beijing Normal University, 100875, Beijing, China)  
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.
