Southwest China’s arid river valleys represent ecologically vulnerable areas with intense human activity. Understanding the historical changes in LULC and land cover projecting impacts of various development scenarios on future have become crucial for regional spatial information management territorial planning. This research analyzes land-use Yuanmou dry-hot valley over a 30-year span from 1990 to 2020. Building upon PLUS model, we established coupled habitat quality multi-scenario simulation model. Four were proposed: natural progression, economic development, ecological conservation, balanced development. We conducted simulations evaluations 2030 using mode, assessing sustainability under varying constraints. During simulation, three distinct RESI regions employed as restricted zones, integrating constraints four scenarios. introduced novel approach based environmental constraint, providing scientific reference sustainable areas. The results indicate that conservation high-to-low constraints, environment is superior other show following: (1) From 2020, aside continuous decrease grassland area, there was an increasing trend water bodies, forests, croplands, construction lands, unused lands valley. (2) By 2030, all scenarios, cropland area expected expand rapidly, while forested will decrease; decline but opposite trends scenarios; (3) Land-use intensity analysis indicated that, by are more likely be converted into forests croplands grasslands, grasslands lands. (4) Sustainable landscape indices reveal exhibit connectivity clustering. Thus, scenario most appropriate strategy future. These findings provide references balancing China.

Clarifying spatiotemporal changes in ecosystem services (ESs) and understanding the trade-offs synergies among different are crucial for effective ES management regional sustainable development. In karst multi-mountainous cities (KMCs), unique landscape pattern, fragile ecological environment, intense human disturbance contribute to accelerated rocky desertification degradation of ESs. Studying provides scientific guidance formulating policies, enhancing value, mitigating KMCs. Therefore, this study analyzes four ESs — habitat quality (HQ), carbon storage (CS), water production (WP), soil retention (SR) using remote sensing images from 2008, 2013, 2018 a typical KMC, aiming reveal investigate driving factors. The key findings as follows: 1) High HQ CS values were scattered patches throughout area, mainly within Urban Remnant Mountain (URM) woodland, but fragmented by construction land. SR WP initially increase then decreased, especially bareland. WP-HQ WP-SR, exhibited tradeoffs, while WP-CS CS-HQ demonstrated synergies. No significant trade-off or synergy relationships observed between HQ-SR CS-SR. 2) URMs, biological patch KMCs' built-up highest degree trade-off/synergy, accounting 32%. When considering only degree, URMs accounted 37%. To improve overall advantages KMCs, greater design consideration preservation essential. 3) Both environmental socio-economic factors influence synergies, with playing dominant role. Future green space planning should consider road layout, land use results can guide policies urban development other

Ecological carbon sinks play a crucial role in global cycling and climate mitigation, making their effective management essential. This study develops novel risk zoning multifactor analysis framework for ecological sink Yunnan Province, China, region recognized its diversity sequestration potential. Our results reveal that high-priority zones, mainly the southwest western regions, cover 20% of total area contain over 60% province's stocks. In contrast, high-risk primarily urbanized show reduction sequestration, with emissions exceeding 25.7 million kg due to urban development landscape degradation. The delineated five distinct zones; urgent intervention control priority restoration long-term conservation integrated zones. Notably, while representing just 9.6% area, are critical protecting 40% comprehensive framework, combining principal component canonical correspondence (PCA-CCA), effectively integrates indicators, socio-economic factors, natural elements. innovative, data-driven approach offers strategic insights into managing balancing integrity socioeconomic needs, providing replicable model ecosystem management.

The expansion of road networks profoundly affects ecological systems by intensifying habitat fragmentation, altering hydrological processes, and exacerbating pollution. However, our understanding the multi-scale spatiotemporal coupling between quality remains limited. Thus, taking Fuzhou City in Southeastern China as a case study (~12,000 km2), we apply bivariate spatial autocorrelation, geographical detectors (GDs), geographically weighted regression (MGWR) to explore interactions quality. Results reveal following: (1) From 2016 2021, kernel density estimation (KDE) analysis network indicates coordinated growth both urban rural areas, with an increase 0.759 km/km2. Analysis based on remote sensing-based index (RSEI) shows decrease from 2000 2016, then trend increasing gradually center area. (2) Predominant tradeoff relationships exist KDE RSEI while notable synergistic emerge ΔKDE ΔRSEI. (3) Multi-scale GD identifies principal factor influencing ΔRSEI, MGWR reveals their significant associations at optimal scale 3000 m. These findings highlight unequal impact quality, underscoring pivotal role changes its dynamics. They offer essential insights for sustainable transport planning.
