To enhance slope stability while fulfilling ecological restoration needs, a composite ecological lattice anchoring system (CELAS) was developed, integrating a lattice structure, anchors, vegetation, and a high-performance turf reinforcement mat (HPTRM). This study, grounded in typical slope conditions along the Pinglu Canal in Guangxi, employed a custom-built recirculating flume and an intelligent rainfall simulation system to replicate diverse hydraulic and precipitation scenarios. The effects of protective materials, vegetation type and density, slope gradient, rainfall intensity, and scour duration on the anti-scour performance of CELAS were systematically investigated. Key parameters—including scour pit depth, scour volume, runoff, and sediment concentration were quantified to elucidate the system's multi-layer synergistic protection mechanism.Experimental results demonstrated that CELAS exhibited superior resistance across a wide range of scour conditions. Compared with bare slopes and conventional vegetation-covered slopes, CELAS reduced rainfall-induced scour volumes by 90.6 % and 29.5 %, respectively, with sediment concentration reductions exceeding 50 %. Under extreme rainfall events (≥80 mm/h) and steep slope conditions, CELAS showed substantially lower increases in scour metrics relative to control groups, indicating reduced sensitivity. In water scour scenarios, CELAS achieved a 78.7 % reduction in scour volume compared to bare slopes and maintained minimal scour responses even under prolonged exposure or vegetation degradation. Under 120-min scour duration, its scour pit depth and volume were 36.5 % and 34.0 % lower, respectively, than those of the vegetated-only slope. When vegetation density declined to 15 g/m<sup>2</sup>, the increase in CELAS scour volume was limited to 15.2 %, significantly less than the 34.4 % observed in the vegetation-only system, highlighting the compensatory role of engineered components.This study establishes a comprehensive multi-layer anti-scour model integrating structural and ecological elements, and systematically elucidates its underlying protection mechanism characterized by energy dissipation, flow disruption, and structural anchorage. The verified robustness of CELAS under extreme hydrological and topographic conditions provides both theoretical insights and practical guidance for the design of resilient ecological slope protection systems, with promising applicability in mountainous hydraulic projects, highway embankments, and riverbank stabilization.</div></div>","PeriodicalId":11490,"journal":{"name":"Ecological Engineering","volume":"222 ","pages":"Article 107810"},"PeriodicalIF":4.1,"publicationDate":"2025-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145097080","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

From 2001 to 2022, NPP showed a fluctuating upward trend, with 25.8 % of the area significantly increasing and only 4.0 % decreasing. Human activities contributed 31.4 % to NPP increases, especially along riverbanks and Populus euphratica restoration zones.

In contrast, during 2018–2020, their contribution reached 16.7 %, highlighting EWC's effectiveness in promoting vegetation recovery. Currently, EWC benefits are mainly concentrated in low-lying floodplains and ecological channels near rivers, while upland areas distant from water sources show limited improvement.

To investigate the seismic response and failure mode of the slope reinforced by this support structure, a large-scale shaking table test was conducted taking into consideration different seismic wave types and excitation amplitudes. The results show that the distribution and amplitude of low-frequency seismic components (<18 Hz) significantly influence slope displacement responses. The sudden change of natural frequency and damping ratio can also reflect the damage degree and deformation stage of the slope. Seismic damage of the slope mainly occurs at the slope shoulder and the slope crest, as well as at the left and right boundaries of the upper part of the shallow overburden. The failure mode is the continuous collapse and sliding of the shallow overburden along the stable surface, which is characterized by the crushing spreading of overburden soil mass. The ecological frame beam structure exhibits effective seismic resistance at peak seismic excitation ≤0.6 g. It is recommended to consider 2.1–3.6 times the elevation amplification effect in the seismic design of ecological frame beam structure.

We assessed two vegetation patches representing distinct successional stages –grassland (pioneer) and shrubland (mature)– on the same mine slope restored eleven years prior. Within each patch, 18 plots (3 transects × 6 sampling units) were established to analyse topography, plant family cover, and soil physicochemical properties.

Fabaceae and other families, typically associated with late-successional stages, were linked to low porosity and deeper soils, while Poaceae and Asteraceae, indicative of early successional stages, were associated with high porosity and shallow soils.
