Vegetation is a crucial component of ecosystems, and understanding the drivers spatial optimization patterns its ecological quality vital for environmental management in middle reaches Yangtze River Urban Agglomeration. Traditional evaluations employing single indices may not fully capture complexity vegetation elements require evaluation through various indicators. Therefore, this study introduced Multi Criteria Ecological Quality Index (VEQI), coupled with cover function indicators, to explore driving factors identify key areas where declines or improves. By constructing Bayesian network VEQI, we identified variables that influence index. Additionally, delineated zones VEQI. The results indicate VEQI exhibits trend transitioning from low values urban centers high suburban rural areas. Over 20 years, average region ranged 10.85% 94.94%. Slope, DEM, type were as significant while precipitation, temperature, nighttime light considered secondary factors. Notably, Hunan, Jiangxi, Hubei provinces, especially western part pinpointed regions. This research only enhances vegetation’s agglomeration but also provides scientific insights protection vegetation.

Amidst the challenges posed by global climate change and accelerated urbanization, structure distribution of land use are shifting dramatically, exacerbating ecological land-use conflicts, particularly in China. Effective resource management requires accurate forecasts cover (LUCC). However, future trajectory LUCC, influenced remains uncertain. This study developed an integrated multi-scenario framework combining system dynamics patch-generating simulation models to predict LUCC high-density urban regions under various Shared Socioeconomic Pathway (SSP)–Representative Concentration (RCP) scenarios. The results showed following: (1) From 2020 2050, cultivated land, unused water projected decrease, while construction is expected increase. (2) Future patterns exhibit significant spatial heterogeneity across three Construction will expand all districts Hangzhou, main areas. Under SSP585 scenario, expansion most significant, it least SSP126 scenario. (3) Distinct factors drive different types. digital elevation model predominant factor for forest grassland, contributing 19.25% 30.76%, respectively. Night light contributes at 13.94% 20.35%, (4) average intensity (LUI) central markedly surpasses that surrounding suburban areas, with Xiacheng having highest LUI Chun’an lowest. area increased significantly smaller than SSP245 These findings offer valuable guidance sustainable planning built environment Hangzhou similarly situated centers worldwide.

Big-data mining approaches based on Artificial Intelligence models can help forecast biodiversity changes before they happen. These predict macroscopic species distribution patterns and trends that inform preventive measures to avoid the loss of ecosystem functions services. They can, therefore, study mitigate climate change implications conservation in fragile ecosystems. Wetlands are particularly ecosystems where poses severe risks has dramatically reduced their size over past century, with profound consequences Through big-data approaches, we future wetland context change. This paper proposes such predictive analysis for a specific wetland: The Massaciuccoli Lake basin Tuscany, Italy. is critical tourist attraction due its rich biodiversity, making it an area interest citizens, tourists, scientists.

The Yangtze River Delta (YRD) region, located inside the Basin, functions as a vital ecological and economic area in China, with its natural environment directly impacting human existence. This study seeks to elucidate spatial temporal evolution of rural resilience region underlying mechanisms by establishing comprehensive assessment framework for resilience, thereby offering scientific foundation policy guidance region’s sustainable development. research first established DPSIR (driving force–pressure–state–impact–response) index system. Subsequently, entropy weighting method TOPSIS were utilized assess rank levels (Shanghai, Jiangsu, Zhejiang, Anhui) from 2012 2022. Ultimately, partial least squares structural equation modeling (PLS-SEM) was employed examine intrinsic logical relationships among five dimensions extract conclusions. effectively met goals SDG 7 (clean water sanitation), 8 (decent work growth), 11 (sustainable cities communities). indicated that (1) level initially declined, then increased, eventually attained condition stabilization. Changes “driving force”, influenced “response level” environmental “pressure”, have affected areas. There is heterogeneity values ranges change provinces, “impact” component exhibiting most substantial evaluation value. findings yield recommendations implementation diverse regional governance, establishment connectivity mechanisms, customization strategies address specific deficiencies each province, systematic enhancement resilience.

With the intensification of socioeconomic activities and climate change, land use conflicts are becoming more serious, posing major obstacles to sustainable territorial space. This study conducted research on conflict zoning control with a view contributing new ideas for prevention resolution risks. By analyzing positioning drawing upon fundamental theories, novel paradigm was proposed. An empirical in Gan River Basin Jiangxi Province by applying comprehensive evaluation method geographical detector, basin divided into six types zones according intensity hierarchy ecosystem service values. The results showed that areas intense conflict, low weak accounted 1.57%, 29.16% 69.26% area, respectively. Of areas, 4.42% lower were while only 0.37% right bank middle reaches conflict. driving factor analysis precipitation, population density policy planning had greater influence likely occur interaction precipitation nighttime light index, NDVI. superimposed image revealed at junctions urban cropland forests upper basin, which mainly caused demand expansion spread agricultural production areas. this agreement actual situation Basin, proving proposed is scientific applicable.
