RDLS macroscopic indicator topographic features that are closely linked local climate, vegetation, biodiversity, use/cover, human activities. These factors significantly influence patterns, processes, functions, which fundamental provision services. Therefore, revealing RDLS's effects has great implications for improving Previous studies have examined distribution pattern, value, temporal spatial evolution services based on regional gradients. However, process their trade-off/synergistic relationship with remains unclear. To address this gap, we conducted study focused Jiuquxi watershed, core Wuyishan National Park. And explored key services, bundles relationships from 2009 2016, using model, InVEST K-mean clustering analysis, ecological index (ESCI), trade-off (ESTD). The results showed (1) including carbon sequestration, water yield purification increased increase during 2009-2016, as did gain area. (2) In can be categorized into three types bundles:eco-fragile bundles, where all four low; eco-regulating high sequestration being dominant; eco-conservation biodiversity dominant. eco-fragile clustered regions low value area value. While had no typically pattern ESCI. From 19% areas region were transformed 18% region. (3) trade-offs/synergies was identified:an inverted U-shape curve secondary or quaternary at its peak (e.g., between synergistic yield) N-type inflection point purification, yield, biodiversity).
