Understanding of the ecosystem services (ESs) supply–demand balance, coupling, and coordination are vital for sustainable development in society. To reveal changing pattern underlying mechanisms matching, ESs, this study, we used InVEST model to quantify supply following three ESs Hunan Province central China from 2000 2018: soil conservation (SC), water yield (WY), carbon retention (CR). Using socioeconomic data, capacity demand food (FS) other were quantitatively evaluated. The Z-score standardized data divide quadrants clarify matching situation. Additionally, elasticity coefficient coupling degree (CCD) evaluate relationship level. Our results indicate following: (1) CR FS increased by 12.67% 19.48%, respectively, while that SC WY decreased 2.57% 22.83%, respectively; SC, WY, CR, 0.329%, 9.43%, 142.05%, 6.23%, respectively. is less than demand, showing a clear contradiction; exceeded demand; both had notable spatial heterogeneity. (2) area high supply–high (HS–HD) supply–low (HS–LD) types decreased, whereas low (LS–LD) (LS–HD) increased. Changsha–Zhuzhou–Xiangtan urban agglomeration (CZX) selected districts northern face shortage ESs. (3) was primarily positive negative. (4) CCD four an unbalanced state demonstrated different trends. This study provides novel insights decision-making regarding optimisation land use Province.

Long-term, daily, and gap-free Normalized Difference Vegetation Index (NDVI) is of great significance for a better Earth system observation. However, gaps contamination are quite severe in current daily NDVI datasets. This study developed 0.05° dataset from 1981-2023 China by combining valid data identification spatiotemporal sequence gap-filling techniques based on the National Oceanic Atmospheric Administration dataset. The generated more than 99.91% area showed an absolute percent bias (|PB|) smaller 1% compared with original data, overall R2 root mean square error (RMSE) 0.79 0.05, respectively. PB RMSE between our MODIS gap-filled (MCD19A3CMG) during 2000 to 2023 7.54% 0.1, three monthly datasets (i.e., GIMMS3g, MOD13C2, SPOT/PROBA) only -5.79%, 4.82%, 2.66%, To best knowledge, this first long-term far.

Microplastic (MP) pollution is a prevalent and global threat to fish. MP contamination was investigated in Harpadon nehereus collected from the principal fishing harbors of India’s northwest coast. A total 213 specimens were major Gujarat state (Jakhau, Okha, Jaffrabad) Maharashtra (Mumbai). In laboratory, morphometric parameters specimens, such as length body weight, measured. The analyzed for isolation using previously documented protocol. MPs quantified under stereomicroscope, physical recorded. All examined found be contaminated with MPs, an abundance 6.98 ± 6.73 MPs/g. maximum recorded at study site Jaffrabad, followed by Jakhau, Mumbai, Okha. Morphometric analysis revealed threads most dominant shape. Black blue 1–2 mm size predominant types. chemical composition extracted polyethylene (PE), polystyrene (PS), polyurethane (PU) polymer compositions. Conclusively, findings highlighted greater menace seafood safety due trophic transfer, which causes hazardous effect on human health.

Fragile ecological regions are the key zones for conducting engineering construction. Exploring intrinsic linkage between vegetation dynamics and climate change human activities is important government to formulate reasonable effective environmental protection policies in different types of ecologically fragile regions. This study used Net Primary Productivity (NPP) as an indicator, based on multitemporal land use data, separate anthropogenic climatic disturbance areas. We revealed dynamics, explored roles temperature precipitation, assessed relative contributions four China from 2001 2019. The indicated that NPP showed increasing trends degrees arid region northwest (AN), Loess Plateau (LP), Tibetan (TP) karst southwest (KS) early 21st century. correlation precipitation was higher than In northern zone, cause increase NPP. drought resistance largely symbolized its ability resist risk degradation. Climate has played a positive role growth Except TP, have contributed construction other regions, with strongest contribution LP (2.10 gC m−2 yr−1), which some progress this region. Due degradation forests grasslands caused by overgrazing farmland reclamation departments should give timely attention security avoid causing future, we suggest natural humanitarian characteristics be considered before formulating measures reasonably taken achieve effectiveness standardization management.

Abstract In light of the recent pressure from global warming, extreme drought events, and deleterious human activity, strength long‐term change trends vegetation in karst regions—in terms their resistance to external disturbances—have not been studied systematically. Therefore, herein, we quantified resilience its nonlinear south China under different environmental gradients by measuring lag‐1 autocorrelation time‐series Normalized Difference Vegetation Index (1990–2018), clarifying driving forces changes. It was shown that monotonous. first stage (pre‐2002), precipitation warming promoted increase regional ( slope = −0.045, p < 0.0001). second (during 2002–2010), increasing trend obvious difficult keep up with productivity, indicating time‐lagged effect ecological restoration projects resilience. third (post‐2010), due continuous advancement projects, increased significantly had largest amplitude −0.128, Simultaneously, gradients, showed significant differentiation characteristics. comparison non‐karst regions, increases were more regions especially post‐2010. With soil depth, exhibited an trend, dependence on soil. At slopes >25°, most obviously meadows largest, which can be preferred type for projects. This research provides another perspective understand ecosystem results will facilitate protection ecosystems.

Identifying the impacts of climatic factors on runoff change has become a central topic in climate and hydrology research. This issue, however, received minimal attention karst watersheds worldwide. Multi-resolution analysis (MRA), continuous wavelet transform (CWT), cross (XWT) coherence (WTC) are used to study teleconnection time frequency between hydrological processes typical watershed at different scales. The main results are: (1) All exhibit cycle 12-month scales with changes, but periodic bandwidth rainfall changes is much wider than that temperature evaporation, indicating factor affecting changes. (2) In other cycles, impact interlacing phenomena positive negative, evaporation mainly negative. (3) response high-energy region low-energy significant-correlation shown correlation smaller phase angle, it slightly lagged 16-month Moreover, lags behind for 1–2 months those regions. (4) It been found there strong effect over runoff, lesser runoff. sheds light teleconnections rainfall, evapotranspiration surface which turn might help attain better management water resources watersheds.
