Clarifying the issues related to supply, demand, and flow of ecosystem services is crucial for regional landscape management. This study employs equivalence factor method demand index quantification analyze supply in Zheng-Bian-Luo region 2000 2020. We used hotspot analysis tools minimum cumulative resistance model establish ecological corridors, identifying spatial paths our site. By calculating volume key corridor value through breakpoint formula field strength theory combining this with ratio regulating service value, we computed compensation amount, thereby realizing service. The results indicate that area balance between gradually decreased deficit increased 43.62% from 2020 along rapid urbanization. total by important corridors was USD 242.40 million 365.92 million, respectively. In 2020, it predicted Luanchuan County would receive totals 237.76 each area, mainly Jinshui District. Our findings support enhancing quality environment optimizing management Yellow River’s Henan section.

A Systematic Review and Meta-Analysis of the Sustainable Impact of Sewage Sludge Application on Soil Organic Matter and Nutrient Content

Sustainability, Journal Year: 2024, Volume and Issue: 16(22), P. 9865 - 9865

Published: Nov. 12, 2024

The increasing scarcity of natural resources makes the linear production model unsustainable, highlighting need for more sustainable practices under umbrella circular economic principles. Sewage sludge emerges as a promising solution to provide soil organic matter (SOM) and nutrients. This meta-analysis evaluated impacts three levels application (low, medium, high) on (OM), nitrogen (N), phosphorus (P), copper (Cu), zinc (Zn) contents, considering different areas experimental conditions worldwide. analysis included 37 studies 355 comparisons, after screening 7625 records, following 2020 PRISMA protocol. effects concentrations, continents, types experiment (field or greenhouse) were evaluated. significantly increased OM, N, Cu, Zn levels, mainly at medium high rates. largest observed in greenhouses, suggesting variation by location environment. Moderators explained part results, but residual heterogeneity test revealed that there is still unexplained variability.
