[Purpose]: Based on the multi-period cross-section data from 2003 to 2023, this paper takes the Yangtze River Economic Belt as the research area to analyze the temporal and spatial changes of the service value of grain ecosystem in the Yangtze River Economic Belt, so as to point out the direction of agricultural green development in the Yangtze River Economic Belt and provide reference for the development of ecosystems in other regions. [Results]: (1) In terms of time, from 2003 to 2023, the total ecosystem service value of grain production in the Yangtze River Economic Belt showed a trend of first increase and then decrease. During the 20 years, the total ecosystem service value of grain production in the Yangtze River Economic Belt increased from 854.584 billion yuan to 1185.349 billion yuan, an increase of 330.765 billion yuan, with an average annual increase of 16.538 billion yuan. The total annual service value of rice, wheat and corn in the Yangtze River Economic Belt is 668.058 billion yuan, 190.577 billion yuan and 190.728 billion yuan respectively. (2) From the perspective of space, from 2003 to 2023, the total ecosystem service value of grain production in the Yangtze River Economic Belt showed the characteristics of “middle reaches > upstream > downstream”. The total value of Anhui, Jiangsu, Hunan, Sichuan and Hubei is at the forefront of the Yangtze River Economic Belt, with an average annual value of 209.770, 169.273, 148.159, 144.897 and 125.506 billion yuan, respectively. The total value of Guizhou, Chongqing, Zhejiang and Shanghai is at the end, with an average annual value of 43.899, 42.308, 32.470 and 5.382 billion yuan respectively. [Conclusion]: The Yangtze River Economic Belt should accelerate the construction of agricultural infrastructure and improve the ecological environment, at the same time, promote agricultural green production, and
