Abstract: The implementation of high-standard basic farmland construction projects has promoted the sustainable development of regional economic, social and land productivity to a certain extent. Six high-standard basic farmland project areas in Heyuan city were selected as research units. Based on the field survey, 17 index construction index systems were established based on the four dimensions of “process logic” frame. Analytic Hierarchy Process to determine the weight, on this basis, the weight obtained by the entropy weight method is modified to obtain the final weight, and the matter-element extension model is used to calculate the degree of correlation to obtain the evaluation result. The results show that the performance of high-standard basic farmland projects in Heyuan city is generally at a “good” level, four of the projects have “good” performance levels, one approaching a “good” level and one at an “excellent” level with no major differences between the projects. However, the evaluation index of land use improvement rate, labor employment improvement rate and project yield rate of project area, as well as the construction and maintenance of farmland infrastructure in the project area are the main factors restricting the improvement of the project's performance level.
