[Objective] The aim of this study is to analyze the potential productivity of temperature, precipitation and climate according to the 40 years meteorological data at 13 weather stations in Jiangsu Province between 1971 and 2010, in order to provide theoretical basis for agricultural industry.[Methods] Based on meteorological data from 13 weather stations, the Miami and Thornthwaite Memorial models were used to calculate the potential productivity of temperature, precipitation and climate. The factors affecting the utilization rate of climate resources and the climatic potential productivity in Jiangsu Province were analyzed by using climate resource utilization formula, correlation analysis and regression analysis.[Results] ① In the past 40 years, the annual average temperature in Jiangsu Province showed an upward trend, and the annual precipitation did not show a regular change. The potential productivity of temperature and precipitation showed a similar trend as the annual mean temperature and annual precipitation. ② The climatic potential productivity showed a slight increase trend, and the climatic resource utilization rate showed a fluctuated rising trend.[Conclusion] Temperature is the main factor that influences climatic potential productivity in Jiangsu Province.
