The middle reaches of the Yangtze River is an important rice production base in China，which has made great contributions to the national food security and ecosystem safety and health.Scientific and reasonable evaluation of the service function value of paddy field ecosystem can provide an important basis for the evolution，improvement and promotion of its service function value and the promotion of the green sustainable development model of paddy field.On the basis of sorting out the connotation of paddy field ecosystem service function and the evaluation system and methods of service function value，this paper classified and compared the methods of evaluating the ecosystem service function of different paddy fields in the middle reaches of the Yangtze River，and summarized the research framework and research ideas of the evaluation of paddy field ecosystem service function value in this region.Due to the differences in types，distribution areas and value evaluation index systems of paddy fields，there are some differences in the evaluation methods of ecosystem service function value and the value of service function per unit area. It is suggested that future research should constantly modify the evaluation index system of different paddy ecosystem services value，improve the evaluation method，and raise the evaluation accuracy.At the same time，this paper also analyzed the service function of some paddy fields in the middle reaches of the Yangtze River，and found that the research perspectives mainly focused on the micro experiment of paddy fields and the macro measurement of provinces，cities and counties. The static evaluation of the service function value of a certain part of the paddy ecosystem or the overall service function value of the system was carried out，but the long-term dynamic tracking research on its value evaluation was insufficient. The research on the net value of paddy field ecosystem services also needs to be further studied.
