The evaluation of the service value of Integrated rice-crayfish ecosystem can provide a reliable theoretical basis for the promotion of the integrated planting and breeding mode,sustainable development and ecological compensation.This paper evaluates the service value evaluation index system of rice and shrimp ecosystem,using the market value method,the alternative value method,and the equivalent factor method.According to the research results,from 2012 to 2022,the ecological value of integrated rice-crayfish ecosystem in Jiangsu province increased from 3.734 billion yuan to 27.327 billion yuan,showing a trend of decreasing first and then increasing.the value of product supply dominates in all individual service values,accounting for 89% by 2022;soil organic matter accumulation and carbon decrease and then increase.
