Abstract: The referenced period was selected and the temperature-affecting coefficient was built to analyze the contribution of climate change to food yield. The results showed that warming occurs mainly in the crop growth season in the 1990s. The contribution rate of the climate warming to food yield increasing in 1990s was 12.6%~17.4%,and 12.3%~20.0% in 2000s.

Key words: climate change, climate yield, climate influence coefficient, climate contribution rate, Yellow River-Huangshui River Valley
