“…However, the microbial community structures in these two sections were distinct ( Figure 3 b). The Yongding River watershed has been divided into the water conservation zone, plain urban zone, and plain suburban zone [ 21 ]. Our sampling sites in the upstream section are located in the water conservation zone, which is slightly disturbed by human activities.…”

“…The Yongding River has received ecological water replenishment through the Yellow River Diversion Project, and the Guanting Reservoir is a key water body within this interbasin project [ 21 , 22 ]. In our study, the Guanting Reservoir was regarded as the starting point in the Beijing section of the Yongding River ( Figure S1 ).…”

Ecological water replenishment via interbasin water diversion projects provides opportunities for ecological river restoration. Untangling water quality changes, microbiota dynamics, and community functions is necessary for sustainable ecological management. Using the Yongding River as a case study, we monitored the water quality and applied genomic sequencing to investigate microbial communities of the river in different stages after ecological water replenishment. Our results showed that river water quality represented by chemical oxygen demand (COD), total nitrogen (TN), and chlorophyll-a (Chl-a) did not change significantly during months after water replenishment. The bacterial community composition varied in different months and river subsections. The Cyanobium_PCC-6307, CL500-29 marine group, and Pseudomonas were dominant in the later stages after water replenishment. Water temperature, pH, and nutrient levels significantly affected the microbial community composition, and ecological restoration may have the potential to influence nitrogen cycling in the river. Our results can provide ecological insights into sustainable water quality maintenance and river management following ecological restoration enabled by ecological water replenishment.

“…Indicators used to quantify ecosystem restoration are influenced by the complexity and dynamics of urban ecosystems, which makes it difficult to establish quantitative criteria for evaluating the success of ecological restoration. However, there is a lack of monitoring efforts at the regional scale to assess the overall effectiveness of ecological restoration projects (Wortley et al, 2013; Zhai et al, 2022). By considering the direct and indirect effects of ecological restoration and its long-term dynamics, we can gain a better understanding of the effectiveness and sustainability of ecological restoration projects (Kong et al, 2018).…”

Ecosystem restoration is a huge task for ecosystem management in the context of rapid urbanization processes from regional governance to global ecosystem restoration in the new era. Significant ecological restoration efforts are underway to improve the ecological quality in highly urbanized areas. However, the path forward is far from clear for those who wish to apply these approaches to manage the urban ecosystem. In this study, we present five core dimensions to guide a landscape-scale management approach to restore ecosystems, with the objective of integrating restoration targets, spatial identification, planning and projects, monitoring and evaluation across the whole ecological restoration. We illustrate some key steps of our approach to landscape-scale ecosystem management through case tudies from Shenzhen City in China. We propose that a landscape ecology pathway is best implemented at regional scale for ecosystem restoration.

“…Despite abundant research on river ecological restoration, most methods have predominantly focused on ecological response analyses under single-factor influences, overlooking the intricate coupling of multiple factors [13][14][15][16][17][18][19]. Furthermore, traditional methodologies have often lacked in-depth exploration of microbial activity and bio-regulation, both of which play central roles in ecosystem thermal equilibrium status [20][21][22][23]. Consequently, current research methodologies may encounter limitations when addressing complex ecological issues.…”

With intensifying global climate change and human activities, small-to-medium river ecosystems in the northern area of China are confronted with unparalleled thermal stress challenges. These rivers play a pivotal role in regional ecological balance, water resource provision, and biodiversity conservation. Although extant studies have addressed ecological restoration of rivers, most methodologies have predominantly focused on ecological responses under single-factor influences, overlooking the intricate coupling of multiple factors. Furthermore, exploration concerning the central role of biological activity and bio-regulation in thermal adaptability remains inadequate. This study aims to meticulously analyze the thermal equilibrium status of river ecosystems in northern China and proposes an optimized ecological restoration decision-making approach that considers multi-factor coupling. By assessing microbial activity indicators, conducting thermal equilibrium and bio-regulation analyses, and introducing a comprehensive decisionmaking framework, this research offers a scientific, systematic, and feasible strategy for the ecological restoration of small-to-medium rivers in northern China, serving also as a reference for parameter determination in wheat-corn Subsurface Drip Irrigation (SDI) in the North China Plain and for water-fertilizer management and decision-making.
