Regional integration is a development strategy that synergizes various components as a whole to maximize overall benefits. The natural heterogeneity and fluidity of ecosystem service (ES) make it a promising target for regional integration. However, the current focus on regional integration was more on the socio-economic factors rather than ecological resources, and the understanding of the supply-demand relationship and potential flow of ecosystem services was still limited. Therefore, we attempted to interpret ecological integration management by linking ES budgets, bundles, and flows in this study. The results showed that the spatial mismatches of ESs supply-demand were observed in all six selected ES types. Most of the ESs deficit regions were concentrated in urban centers, while ES surplus regions were scattered in surrounding rural areas. Multiple heterogeneous ES resources could ideally benefit an additional 0.13-4.84 million people in 9-70 townships through potential ES flows under ecological integration management. Therefore, we connected the service provisioning areas (SPAs) and service beneficiary areas (SBAs) with three types of ES flows and drew the potential provider-beneficiary relationship networks at the townships/bundles scale, demonstrating the interactive relationship of ecological integration within the region. On this basis, we also proposed the applicability matrix of governance tools for the first time according to the type of ES flows, and then put forward the corresponding governance opinions around the two aspects of "improving ES budges within clusters" and "strengthening ES flow among clusters". This study provided an ecological perspective for understanding regional integration, and relevant conclusions can inform environmental policy priorities for sustainable decision-making in urbanized areas.
区域一体化是一种发展战略，它将各个组成部分作为一个整体进行协同，以实现整体效益最大化。生态系统服务（ES）的自然异质性和流动性使其成为区域一体化的一个有前景的目标。然而，当前对区域一体化的关注更多集中在社会经济因素而非生态资源上，对生态系统服务的供需关系和潜在流动的理解仍然有限。因此，在本研究中，我们试图通过将生态系统服务预算、束和流动联系起来，来阐释生态一体化管理。结果表明，在所选择的六种生态系统服务类型中均观察到了生态系统服务供需的空间不匹配。大多数生态系统服务赤字区域集中在城市中心，而生态系统服务盈余区域则分散在周边农村地区。在生态一体化管理下，多种异质的生态系统服务资源理论上可通过潜在的生态系统服务流动，使9至70个乡镇中的另外13万至484万人受益。因此，我们用三种类型的生态系统服务流动连接了服务提供区（SPA）和服务受益区（SBA），并绘制了乡镇/束尺度上潜在的提供者-受益者关系网络，展示了区域内生态一体化的互动关系。在此基础上，我们还首次根据生态系统服务流动类型提出了治理工具的适用性矩阵，然后围绕“改善集群内的生态系统服务预算”和“加强集群间的生态系统服务流动”这两个方面提出了相应的治理意见。本研究为理解区域一体化提供了一个生态视角，相关结论可为城市化地区可持续决策的环境政策重点提供参考。
