| 英文摘要 | Eutrophication severely degrades coastal ecosystems, prompting extensive restoration initiatives worldwide. However, current coastal management strategies in semi-enclosed bays often fail to adequately assess ecosystem recovery because they rely predominantly on superficial water-quality indicators or the return of select taxa. These conventional metrics overlook deeper impairments in ecosystem functioning that ultimately dictate longterm restoration success. To address this critical management gap, we evaluated the ecosystem functioning and energy dynamics of two eutrophic bays (Sanmen and Yueqing Bays) in the East China Sea that share similar restoration histories but differ in geomorphology. Using Ecopath models as a diagnostic tool, we found that despite ongoing restoration, both systems exhibit imbalanced communities with bottom-heavy biomass and severely underutilized primary production due to bottlenecks in grazing and detrital pathways. Furthermore, departures in maturity indicators (total primary production-biomass ratios, connectance, and system omnivory) demonstrate that these food webs remain simplified and functionally constrained. Crucially for future management planning, our analysis identified differing regulatory mechanisms: Sanmen Bay is driven by top-down control, while Yueqing Bay exhibits greater bottom-up influence. Collectively, these findings highlight that relying solely on conventional metrics leaves coastal managers blind to hidden functional degradation. By integrating trophic network analyses, coastal managers can move beyond water-quality targets to tailor site-specific, multi-trophic interventions and design more adaptive, ecosystem-based restoration strategies. |
