After analyzing the climate change trend in Jiayu County, Hubei Province, based on the date of the main meteorological factors observed during the period of 1957-2012, the response of climate productivity to climate change is calculated and predicted by using the Thomthwaite Memoria model. The results show: (1) in the last 56 years, the climate tendency has changed from cold-dry to cold-wet, end with warm-wet. The annual average temperature and rainfall are 17.22℃ and 1399.9mm, respectively increased with the rate of 0.221℃ /10a and 10.961mm/10a. (2) Seasonal temperature rise at different rates, but seasonal precipitation trend is not uniform. It has witnessed decreased trend in spring and autumn while it appears increasing trend in summer and winter with the speed of 19.333 mm /10a and 6.810mm/10a. Overall, the warming-drying climate tendency is obvious. (3)The warm-wet climate environment was the most advantageous to the agricultural production of Jiayu County whose production number was 5.34%-15.68%, while the cold-dry climate was the most disadvantageous to the agricultural production whose production scope was 5.48% -17.05%. Nowadays, the warming-wetting climate tendency of Jiayu County is benefit to climate productivity.
