Interactions of Ecosystem Services and Management Optimization in Complex Hilly Mountainous Environments: A Case Study from Southern China

Land, Journal Year: 2025, Volume and Issue: 14(4), P. 717 - 717

Published: March 27, 2025

Hilly mountainous regions are ecologically complex, featuring diverse environmental ecosystem services (ESs) and intricate interactions. However, the variability, drivers, management of these ESs remain poorly understood, particularly in with significant topographical climatic heterogeneity. This study focuses on southern hilly mountain belt China, examining five key services: food production (FP), carbon storage (CS), water yield (WY), habitat quality (HQ), soil conservation (SC). examines across long-term, pixel, regional scales, exploring interactive relationships identifying driving factors cluster characteristics. The results indicate following: (1) Over past 23 years, although have increased, has declined. (2) From a spatial perspective, differences trade-offs synergies years relatively small. observed when considering continuous temporal change, trade-off generally prevalent. Additionally, distribution is also influenced by combination factors. (3) Climatic, vegetation, topographical, socioeconomic influencing changes ESs. For instance, climate–vegetation interactions enhance conservation. Socioeconomic factors, though less impactful, optimize through land policy. (4) We found that ecological priority region covers largest area, followed agricultural development zone, forestry integrated security zone. These findings deepen our understanding regions, providing actionable insights for enhancing sustainable complex landscapes.

Towards a Mechanistic Understanding of Legume Functioning in Natural Restoration of Degraded Ecosystem: Legume‐Specific Impacts on Nitrogen Transformation Processes

Plant Cell & Environment, Journal Year: 2025, Volume and Issue: unknown

ABSTRACT Legumes have important functions in degraded ecosystems as they can mediate atmospheric nitrogen (N) inputs and increase soil N availability. However, it remains unclear whether legumes affect availability only through biological fixation or stimulating microbial transformations. In this study, nine native four non‐legumes were collected following a 9‐year natural vegetation restoration experiment karst rocky desertification area. Leaf N/phosphorus (P) ratios various pool compositions analyzed gross transformation rates determined by 15 tracing techniques. exhibited higher leaf δ values increased contents of total N, biomass inorganic compared to non‒legumes. Legume content N/P ratio (26.7 g kg ‒1 20.7) significantly exceeded those non‒legumes (14.2 14.5). Our results indicate that decreased plant limitation after 9 years succession, with effects varying between species related processes. Species low high organic mineralization ( M Norg ) ammonium oxidation nitrate O NH4 ), both which supply (especially nitrate). This effect was more pronounced rhizosphere than bulk soil. positively correlated p < 0.01) carbon, water holding capacity, calcium well N:P ratios, indicating improve quality supply, thereby alleviating limitation. highlight the importance cycling availability, is often limiting factor for ecosystems.
