Climate Change in Shandong Province and Its Influence on Potentiality of Wheat Production

Based on the data of temperature,precipitation,sunshine from 1961 to 1998 at 27 meteorological stations,the climatic variation characteristics of Shandong Province are analyzed and the productive potentialities of the winter wheat is calculated and analyzed. The result shows that the annual and quarterly average temperature of Shandong Province has a tendency to increase the production of winter wheat,the precipitation has a tendency to reduce. The warmer climate is stable to the improvement of the productive potentialities. The total variation tendency of the climate productive potentialities of the winter wheat is to rise,but smaller than that of sunshine.
