| Abstract: |
| The temperature attribute,sunlight attribute,precipitation attribute model and climatic suitability model of winter wheat are set up by using Fuzzy mathematics theory and referring to former study,and the temperature attribute, sunlight attribute,precipitation attribute and climatic suitability of different growing periods have been calculated separately with the model and related data during 1960～2005 of Hebei Province.The results show that temperature attribute and sunlight attribute are relatively big,and precipitation attribute is small in Hebei Province.So light and heat resources can meet the demands of winter wheat growing,and precipitation becomes the limited factor.Climatic suitability of winter wheat has decreasing trend,and the decade decreasing rate is 0.012.Among climatic suitability of the tillering stage,turning green date and jointing stage during winter wheat growth have a great change range,which is in accord with the climate character of Hebei Province. |
