Abstract: Garden is an important type of natural resources with both production and ecological functions. The implementation of differentiated management for the intensity of production and ecological functions is an important means to effectively protect and utilize garden resources. In this study, the orchard quality and ecological product value were used to characterize the production and ecological functions of orchards in Xinfeng County, Jiangxi Province. Moreover, the spatial differentiation characteristics were described. The random forest model was used to explore the importance of factor characteristics. Pearson correlation analysis was used to explore the correlation between orchard quality and ecological product value. Based on such relationship, differentiated management modes were proposed. The results showed that: (1) The value of ecological products per unit of citrus orchards showed a trend of higher in the surrounding areas and lower in the middle areas. (2) The overall quality of citrus orchards was high, with a distribution pattern of higher in the middle areas and lower in the surrounding areas. (3) There was a negative correlation between orchard quality and unit ecological product value. (4) The patches of citrus orchards were divided into four management types: compound key type, quality potential type, ecological potential type, and transformation and upgrading type. The corresponding management measures and development suggestions were put forward. There are trade-offs between the quality of citrus orchards and the value of ecological products in Xinfeng County. Decision makers should use the existing orchard grading evaluation to control the overall development direction of orchard quality, prioritize the development of areas with good soil texture and high organic matter content, reduce human interference, and optimize road construction.
