Oil crops, as one of the most important crops in China, is significantly sensitive to climate change. In China, the self- sufficiency in edible oil is relative low at present, which results in a severe imbalance between supply and demand. Consequently, edible oil production is dramatically important to food security in China. Observations have shown that climate change have considerable impact on the oil crops production. Therefore, climate change impact estimation on oil crops is becoming more and more important in terms of increasing the self- sufficiency of edible oil and safeguarding the food security. In this study, based on literature review, we summarized climate change impact on Chinese three major oil crops, such as peanut, soybean and rape, including the major methodologies and impacts on the growth and development and yield, the quality and the cropping system of oil crops. Finally, we discussed the deficiencies and the future expectations.
