Nature-based solutions are critical for ecological restoration in reclaimed areas, especially in promoting vegetation recovery. However, current vegetation restoration in reclaimed areas mainly relies on artificial greening, without deep insights on the restoration of natural vegetation. This study assessed aboveground plant communities and soil seed banks (SSBs) over 8–14 years of natural ecological succession in the reclamation area, using field surveys and remote sensing analyses. Soil and seed characteristics were evaluated, and a plant-soil-seed bank quality index (QI) was calculated. Structural equation modeling (SEM) was used to explore relationships between vegetation, soil properties, seed bank, and QI. The results show that after 8–14 years of natural recovery, the diversity of aboveground plant species remained stable, indicating that woody plants play a key role in stabilizing community composition. However, the species richness of the SSBs decreased after 12 years, with wind and self-reproduction as dominant modes of seed dispersal. Moreover, the potential for natural vegetation recovery increased over time. Soil total salinity (TS), available nitrogen (AN), and available phosphorus (AP) were identified as the main drivers affecting the natural succession of SSBs and aboveground vegetation. Therefore, the potential for natural vegetation recovery in reclamation areas increases over time, remains stable in space, and was mainly driven by soil factors. This study can provide a typical case for the natural restoration of vegetation in sea reclamation areas.</div></div>","PeriodicalId":11490,"journal":{"name":"Ecological Engineering","volume":"220 ","pages":"Article 107730"},"PeriodicalIF":3.9,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144653004","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}

The results showed that the POM mass percentage and Cd mass load in POM increased as POM size decreased, with 56.93 % of Cd (on average) concentrated in the smallest fraction (0.053–0.25 mm). Manure application increased the absolute mass of all POM sizes (−3.53 % to 45.14 %), although their mass percentages remained stable.

However, higher recalcification (50 % and 100 %) diminished manure-induced enrichment. The combination of 5 % manure with low recalcification (25 %) resulted in the lowest Cd content in wheat grains. Soil carbon component and redundancy analyses indicated that Cd enrichment in POM was favored by an organic carbon content >20 g kg<sup>−1</sup> and an inorganic/organic carbon ratio < 1.

Grain for green project (GGP) and low-efficiency forest renovation project (LFRP) accounted for the largest areas in both periods, together exceeding 70 %. Significant spatial heterogeneity in ESs variation and CCERP distribution was observed across terrain gradients: ESs in Rank3 exhibited continuous improvement, while those in Rank1 showed high fluctuation. Over 80 % of construction land reclamation project (CLRP), dryland-to-paddy conversion project (DCP), and water restoration project (WRP) were concentrated in Rank1 and Rank2, while more than 70 % of GGP and LFRP were distributed in Rank2 and Rank3. CLRP significantly improved carbon storage (CS), habitat quality (HQ), and net primary productivity (NPP) in Rank1; DCP enhanced soil retention (SR) and water retention (WR) in Rank1 and Rank2; GGP and LFRP had positive effects on all ESs, with the most pronounced impact on CS and HQ in Rank2 and Rank3. CS and HQ in Rank1 and Rank2 were more sensitive to construction land expansion, while NPP, SR, and WR in Rank2 and Rank3 were more influenced by precipitation and temperature change.

Here, we assessed the biogeochemical recovery of ancient, previously buried, hydric soil on a restored floodplain surface and its potential for providing denitrification ecosystem services. Relict hydric soil along with contemporary wetland soils were evaluated for three years at the Gramies Run restoration site in Maryland. Porewater sampling was conducted monthly, and soil samples were collected every six months, both of which were evaluated for total carbon (C) and nitrogen (N), nitrate and ammonium-N, N process rates (denitrification and net nitrification and mineralization) and living microbial biomass. Oxidation of hydric soils released inorganic N, but the dissolved N concentrations were low (≤ 1 mg/L). Denitrification rates in the hydric soil were low in year 1 (1–4 μg kg<sup>−1</sup> h<sup>−1</sup>) but slowly increased to higher values by year 3 (10–47 μg kg<sup>−1</sup> h<sup>−1</sup>). Our observations suggest that relict hydric soils will require three or more years to provide restoration ecosystem services like improved denitrification and slow gains must be considered in water quality expectations from restoration.
