This paper analyses the main features of the climatic change in the past 15 years compared with that of the last 50 years, and the emphasis of the discussion is directed to the relations between climatic change, natural disasters of agriculture and grain yields in China. The conclusion arises that precipitation is the major factor to affect grain yields in China , while the effects on grain yields caused by temperature variation appear obvious in high latitude areas and high elevation areas.doi:10.2480/agrmet.52.923 fatcat:5tklv5srarebjh4b4ryf6y7q7i
