Abstract: It is of great significance for building a diversified food supply system and ensuring national ecological security to explore the spatial coordination relationship between agricultural food supply services and landscape patterns in major grain producing areas. This article took Lianyungang City, Jiangsu Province as an example and used methods such as coupled co-scheduling and geographically weighted regression to analyze the coupling and coordinated evolution characteristics of food supply services and landscape patterns from 2009 to 2022. We also explored the influencing factors and proposed zoning optimization suggestions. The results showed that: (1) The overall level of food supply services in Lianyungang City followed a spatial pattern of high levels in the central and southeastern regions, low levels in the northern, coastal, and urban areas. The level was slightly higher in the eastern region than in the western region. The overall landscape pattern index showed an increasing trend, and the spatial pattern tended to be dispersed and evenly distributed from high value clustering. (2) Food supply services and landscape patterns showed a trend of high - high distribution in the southern region, and low - low and low - high distribution in the northern region. (3) The coupling and coordination could be divided into high coordination - food supply lag zone, moderate coordination - food supply lag zone, basic coordination - food supply lag zone, moderate imbalance - food supply lag zone, and severe imbalance - food supply lag zone, which were mainly significantly affected by the distance from rivers, distance from town centers, elevation, soil type, and landscape development intensity. It was concluded that the various coordinated zoning of food supply services and landscape patterns should promote the coordinated development of the two aspects. The potential measures might include a reduction of human disturbance and an enhancement of landscape characterization. It was also important to conduct a rational planning of various land use to reduce the segmentation of various landscapes. In addition, it was necessary to improve a comprehensive land use, to monitor the use of farmland in the imbalanced areas, and to reasonable guide the concentration and connection of farmland to enhance the multifunctional properties of farmland.
