However, these changes might lead to uncertainties in revegetation risks in the future because the cost-effectiveness of planting different forest species for revegetation remains unknown. Therefore, we are to evaluate the cost-effectiveness of planting economic and ecological forests in Shaanxi Province, China. Since the implementation of the SLCP, greening trends in Shaanxi Province have increased. It takes approximately four years after afforestation to maximize its ecological benefits. The main investment effect of ecological forests on revegetation is significant and positive; however, the investment return of economic forests is less pronounced. Furthermore, the remarkable crowding-out effect indicates that more economic forest investments would reduce the marginal contribution of ecological forest's to revegetation. Finally, all financial funds invested in ecological forests would bring maximum ecological returns. Hence, policy changes would result in risks of degraded vegetation and a decrease in the efficiency of fiscal investment. The government should be cautious regarding the forestry policy changes in the new round of the SLCP and encourage farmers to select appropriate forest species for afforestation aimed at ecological goals.</div></div>","PeriodicalId":11490,"journal":{"name":"Ecological Engineering","volume":"214 ","pages":"Article 107580"},"PeriodicalIF":3.9,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143488790","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}

This study presents a quantitative investigation of the impacts of deep-seated landslides, which have actively supplied sediments for more than one hundred years, on damaged trees, incorporating various factors such as distance from landslide borders, slope gradient, factor of safety (FS), Wind Exposure Index (WEI), Convergence Index, and plan curvature in four landslides in Japan (Shichimenzan, Senmai, Sarugare, and Akakuzure). The study aims to enhance our understanding of the relationship between landslides and vegetation, providing valuable insights for landslide management and ecological restoration. Using a combination of field surveys and high-resolution UAV (Unmanned Aerial Vehicle) images from 2020 and 2023, a total of 2057 damaged trees were identified across all four study landslide areas. Statistical analysis (<em>One-Way ANOVA</em>) show there is significant differences among different damaged tree types in studied variables in 99 % of confidence level. Analysis of the distance from landslide borders revealed significant differences among damaged tree types. The average distance of Fallen and Green (<em>FG</em>) trees from the landslide borders was found to be 7.3 m, indicating their proximity to the affected area. Furthermore, the density of FG trees within the expanded area of the landslide was observed to be higher. Stand and Dead (<em>SD</em>) trees, in contrast, were situated at an average distance of 68.6 m from landslide border, suggesting their vulnerability to animal-related damages. Fallen and dead (<em>FD</em>) trees were associated with steep slope gradients, averaging 40.8 degrees, and exhibited low FS values (0.87), indicating their susceptibility to slope instability. Stand and Dead partially trees (<em>SDP</em>) and <em>SD</em> trees demonstrated higher FS values suggesting their presence in areas with superior slope stability. In addition, results show, <em>FG</em>, <em>SD</em>, and <em>SDP</em> trees were predominantly located in wind-exposed higher elevation areas. <em>FD</em> trees were primarily situated in areas with negative Convergence Index values (−0.7), indicating slope convergence. <em>FG</em> and <em>SDP</em> trees were found in areas with positive values, suggesting slope divergence.

This study aimed to assess mesofauna attributes and microbial activity in a minesoil restored for 14.6 years with perennial grasses in Candiota, and to explore their relationships with soil physical, chemical, and humus properties. Our previous research showed that <em>Urochloa brizantha</em> improved soil physical and chemical attributes more effectively than other grasses, suggesting stronger links between soil biology and these properties in this treatment. After 14.6 years of revegetation with <em>Hemarthria altissima</em>, <em>Cynodon dactylon</em>, <em>Panicum maximum</em>, <em>Urochloa humidicola</em>, and <em>U. brizantha</em> a series of minesoil biological, chemical and physical attributes (0.00–0.10 m layer) were assessed. Control site consisted of minesoil with spontaneous vegetation. <em>U. brizantha</em> treatment exhibited significantly lower bulk density (1.2 Mg m⁻³) and higher macroporosity (0.16 m³ m⁻³) and total porosity (0.48 m³ m⁻³) compared to <em>C. dactylon</em> (1.4 Mg m⁻³, 0.07 and 0.40 m³ m⁻³, respectively).
