In this paper,the effects of rice and shrimp farming on rice yield,water quality and farmer income were analyzed.An econometric model based on simplified form of crop yield was used to compare the differences and impact degree of rice and shrimp farming data in Jingzhou city from 2018 to 2020.The results showed that rice shrimp culture could significantly improve rice yield and farmers'income,but had some effects on water quality,and the degree of impact increased with the increase of crayfish density.It is suggested that the government should strengthen the technical guidance and supervision of rice and shrimp farming,and promote the optimized cultivation mode of rice and shrimp ro-tational cultivation.
