ABSTRACT Carbon stock is a key element of land‐based ecosystems and serves as one the indicators for assessing SDG 15.3, which undergoes direct or indirect effects due to changes in land use. Utilizing central Yunnan urban agglomeration (CYUA) study region, we constructed Markov‐Multi‐Objective‐patch‐generating use simulation (Markov‐MOP‐PLUS) coupled model across four distinct scenarios: sustainable development scenario (SDS), economic (EDS), ecological protection (EPS), natural (NDS) year...

Investigating spatio-temporal differentiation patterns of land-use conflicts in mountainous and flatland regions provides critical insights for optimizing spatial regulation strategies advancing sustainable regional development. Using the Urban Agglomeration Central Yunnan (UACY) as a case study, production–living–ecological space (PLES) was classified through functional dominance analysis based on 2010–2020 geospatial datasets. Spatio-temporal evolution mountain–dam were analyzed using...
