Ecosystem Service Trade-Offs and Synergies in a Temperate Agricultural Region in Northeast China

Remote Sensing, Journal Year: 2025, Volume and Issue: 17(5), P. 852 - 852

Ecosystem services (ESs) are essential for balancing environmental sustainability and socio-economic development. However, the of ESs their relationships increasingly threatened by global climate change intensifying human activities, particularly in ecologically sensitive agriculturally-intensive regions. The Songnen Plain, a crucial agricultural region Northeast China, faces considerable challenges sustaining its due to overexploitation land, degradation, variability. This study assessed five key Plain from 2000 2020 across multiple scales: habitat quality (HQ), soil conservation (SC), water yield (WY), food production (FP), windbreaking sand fixing (WS). We evaluated trade-offs synergies between these ESs, as well driving factors main ES trade-offs. Our findings indicate that provisioning (WY FP) regulating (SC WS) improved over time, with FP exhibiting most significant increase at 203.90%, while supporting (HQ) declined 32.61%. primary ecosystem service multifunctionality areas were those provided FP, SC, WY, accounting 58% total. varied spatial scales, stronger being observed pixel scale more pronounced county scale. Climate factors, precipitation temperature, played role shaping than anthropogenic factors. provides valuable insights into restoration sustainable management temperate regions, implications protection northeastern black safeguarding national security.

The Impact of Nature Reserves on the Ecological Network of Urban Agglomerations—A Case Study of the Urban Agglomeration in the Middle Reaches of the Yangtze River

Land, Journal Year: 2025, Volume and Issue: 14(5), P. 1054 - 1054

Published: May 13, 2025

The accelerated development of urban agglomerations in China has resulted the significant regional expansion infrastructure and spaces, which led to fragmentation habitats degradation ecosystem function. Ecological networks have been shown reconnect isolated habitat patches within by identifying ecological sources constructing corridors, could enhance security. Nature reserves, as critical areas for protection key species ecosystems, play a vital role this process. Investigating influence nature reserves on helps integrate resources, optimize network structures, cross-departmental coordination reserve management environment protection. Using agglomeration middle reaches Yangtze River case study, research analyzes impact agglomerations. Initially, source are identified using “Quality-Morphology-Connectivity” evaluation model. Different types then superimposed create four distinct schemes. Subsequently, resistance surface is constructed through comprehensive method assess barriers. Then, corridors generated circuit theory tools. Finally, comparison effectiveness conducted 12 landscape pattern metrics. results indicate several points. Firstly, inclusion supplement increase corridor numbers, thereby enhancing optimization effect agglomerations’ threefold. Secondly, closely related spatial scale patches, patch consistency should be considered prevent functionality loss. Thirdly, establishing cross-regional collaborative mechanism recommended organically with networks. These provide data-driven foundation inform effective strategies promote construction civilization

Multi-Scale Gross Ecosystem Product (GEP) Valuation for Wetland Ecosystems: A Case Study of Lishui City

Water, Journal Year: 2024, Volume and Issue: 16(24), P. 3554 - 3554

Published: Dec. 10, 2024

Traditional gross ecosystem product (GEP) accounting methods often operate at macro scales, failing to reflect the localized and nuanced values of wetland ecosystems. This study addresses these challenges by introducing a fine-grained classification system based on adaptation international standards. The framework integrates high-precision national land surveys remote sensing quantitative analysis while incorporating fisheries resource models, climate regulation beneficiary mapping, visitor interpolation address data scarcity related human activities. approach refines spatial calculation for functional quantity fine scales. results demonstrate that refined maintains consistency with traditional in total value adapting multi-scale accounting, filling gaps small medium scales providing more accurate representation characteristics. Additionally, highlights dominance cultural services GEP, emphasizing need balance regulatory ensure fairness decision-making. Finally, village-scale decision-support model is proposed, offering actionable guidance management sustainable development planning.
