摘要： High-standard farmland construction is critical for sustainable land use and food security in China. Currently, scientific siting delineation for high-standard farmland at the county level is lacking. Delineation through evaluation and zoning is essential to improve land productivity. This study focuses on Dali County in Shaanxi Province, Fenwei Plain. It analyzes cultivated land changes using the land use transfer matrix and the PLUS. By integrating macro "township-parcel-grid" and micro "farmer" perspective, it establishes a comprehensive evaluation system for high-standard farmland delineation. We delineate construction zones and evaluate potential effect of high-standard farmland. The results reveal that: (1) From 2000 to 2020, the cultivated land area generally decreased. The permanent basic farmland positively contributes to the increase of cultivated land. Land use simulation in 2030 results show that the urgency for land consolidation. (2) The delineated high-standard farmland area in Dali is 85,081 hm(2), with comprehensive evaluation index values ranging from 0.2229 to 0.5970, indicating that Dali has the potential for continuous construction of high-standard farmland. (3) This study zones high-standard farmland construction according to the difficulty and time sequence. Delineated high-standard farmland can play potential effect of agglomeration and demonstration, sustainable and coordinated development and grain production capacity increasing. We offer a scientific method for delineating zones of high-standard farmland within county, providing recommendations for sustainable high-standard farmland construction. It serves as a reference for the gradual conversion of all permanent basic farmland to high-standard farmland in China.
