Carbon sink service (CSS) is crucial in addressing global warming and provides theoretical support for research on human‒system coupling. CSS generation, flow, utilization the composite ecosystem of mountains, rivers, forests, farmlands, lakes, grasslands (CEMRFFLG) sustainable development. Quantifying coupled supply‒flow‒demand processes mechanisms CEMRFFLG remains a pressing issue study carbon flows (CSSFs). First, quantify supply demand situation Chongqing. Second, coupling process CSSF among water, forest, farmland, grassland subsystems explored via breakpoint model combined with metacoupling framework. Finally, multiscenario simulation was performed to reveal its flow mechanism. The results show that: (1) Net primary productivity (NPP) mainly comes from emissions (CEs) come farmland. (2) During telecoupling, forest subsystem has highest total value outflow inflow plots, accounting 35.51% 61.24% total, respectively. (3) moves areas human activities. This paper proposes optimization suggestions essential achieving complex ecosystem's

This study incorporated ecological footprint (EF) consumption into a framework to assess well-being. A model and implementation for characterizing regional net well-being were then developed. Using the Guanzhong Plain Urban Agglomeration (GPUA) as case study, land use data from 2000 2020 utilized calculate ecosystem service value (ESV), representing supply side of functions. Simultaneously, EF was assessed demand side. Taking account level economic development characteristics people’s living, evaluation constructed arrive at deficit or surplus situation. The results indicated that: (1) overall ESV GPUA follows trend initial growth followed by decline. Woodland, grassland, farmland are main contributors total ESV, with regulating supporting services accounting more than 80% value. (2) in shows significant upward trend, increasing over 70% on average. carrying capacity has slightly increased, biologically productive area that can support human activities expanding 1909.49 million hectares. Additionally, urban agglomeration cities tended stabilize since 2015. (3) Since 2010, anthropogenic continued exceed capacity, resulting an deficit. average compensation per hectare increased 35.588 CNY 187.110 CNY. offers theoretical foundation definition research providing accurate assessment multiple scales. It is expected this approach will help reduce opportunity costs associated protection, while promoting balanced preservation.

Assessing the Supply–Demand Matching and Spatial Flow of Urban Cultural Ecosystem Services: Based on Geospatial Data and User Interaction Data

Land, Год журнала: 2025, Номер 14(4), С. 773 - 773

Cultural ecosystem services (CESs) reflect the interaction between ecosystems and human well-being. Owing to constraints in data availability existing methodological limitations, deriving information from non-material attributes was inadequate. We took Yulin City, located northern Shaanxi Loess Plateau, as a case study. Based on open-source geospatial user social media, coupled multi-source model applied elucidate spatial distribution of CESs’ supply–demand flow. The Maxent LDA were utilized quantify CES supply–demand, whereas breakpoint gravity explain direction intensity results indicated following: (1) aesthetic most perceivable Yulin, with 27% high supply areas four demand topics. And perception educational least pronounced, only 2% two (2) exhibited notable mismatching matching area constituting approximately 10%. In center city, CESs displayed pattern deficit, while farther city presented surplus. (3) flow followed movement peripheral counties central less developed more counties. proposed following targeted recommendations: introducing low-perception promote enhancement (ESs); alleviating mismatches by enhancing transportation accessibility protecting ecological environment. Simultaneously, attention should be directed towards developmental disparities counties, providing differentiated guidance for Our study provided theoretical foundation understanding offered scientific insights development urban CES.
