[Objective] The aims of this study are to reveal the spatiotemporal pattern changes of ecological land that arise from the combination of basic ecological land and productive ecological land, and to provide the support for the exploration of practical ecological significance of fruit production to the area with limited forest resources. [Methods] The quantitative changes, transfer processes, and spatial hot and cold spots of ecological land were analyzed by using data from the second and third land resources survey. [Results] The total ecological land in Luochuan County increased by 4 703.87 hm2 between 2009 and 2019, with forest land and orchard land having the most significant gains of 23 103.4 hm2 and 9 025.31 hm2, respectively. Additionally, the county's stable ecological land area reached up to 108 583.1 hm2, with woodland comprising the main stable ecological land in the northern low hilly area, accounting for 90.04% of the region. The central and southern tablelands contained a significant proportion of stable ecological land, with productive ecological land accounting for 44.35% and 45.7% of the total stable ecological land, respectively. The proportion of ecological land was analyzed by using local spatial autocorrelation, revealing that the aggregation pattern of basic ecological land remained consistent between 2009 and 2019. However, the spatial aggregation pattern of productive ecological land changed considerably during this period. Specifically, the high-high aggregation area and low-low aggregation area increased by 6 079.64 hm2 and 10 792.11 hm2, respectively, while the statistically insignificant area decreased by 18 309.15 hm2. The change in productive ecological land primarily represented by garden land, significantly impacted the county's ecological land pattern. This change led to the decrease in the high-high and low-low aggregation areas by 18 262.62 hm2 and 8 373.14 hm2, respectively, and the increase in the statistically insignificant area by 27 725.61 hm2. Notably, the improved income level of rural farmers and played a crucial role in promoting the sustainable development of the regional environment. [Conclusions] The productive ecological land represented by orchards had a great impact on the stability of ecological land in Luochuan County, and the ecological research on fruit production in areas with limited forest land resources should be strengthened in the future.
