Abstract：The present study made a risk assessment of rice yield reduction rates in different areas of Liaoning Province.Based on the rice production data collected from 1993 to 2013 in this province,trend yields were obtained by using the linear sliding average method, rice yield reduction rates in different areas of Liaoning Province were estimated according to the risk analysis model of information diffu-sion theory.Based on the estimated average yield rates and risk indexes,Liaoning Province was divided into five area groups with differ-ent risk levels:low risk areas,relatively low risk areas,medium risk areas,relatively high risk areas,and high risk areas.As a result, Panjin area is suitable for rice cultivation due to its good climate conditions and fertile soil;by contrast,western areas of Liaoning Prov-ince are not suitable for planting rice because of local drought and heat conditions and higher rice production risks.
