Ecological restoration projects (ERPs) are an indispensable component of natural climate solutions and have proven to be very important for reversing environmental degradation in vulnerable regions enhancing ecosystem services. However, the level enhancement would inevitably influenced by global drought rising CO2 , which remain less investigated. In this study, we took Beijing-Tianjin sand source region (which has experienced long-term ERPs), China, as example combined process-based...

The tradeoffs and synergies of ecosystem services are widely discussed recognized. However, explicit information for understanding managing the complex relationships multiple at regional scales is still lacking, which often leads to degradation important due one service being enhanced over another. We assessed biodiversity production nine ESs (ecosystem services) across 779 counties in Yangtze River Basin, largest basin China. Then, we mapped distribution ES each county used correlations...

To improve the precision of water quality forecasting, variational mode decomposition (VMD) method was used to denoise total nitrogen (TN) and phosphorus (TP) time series obtained several high- low-frequency components at four online surface monitoring stations in Poyang Lake. For each aforementioned high-frequency components, a long short-term memory (LSTM) network introduced achieve excellent prediction results. Meanwhile, novel metaheuristic optimization algorithm, called chaos sparrow...

Ecological compensation is a crucial policy instrument that realigns the benefits of stakeholders to ecosystem service provision. However, spatial disconnections between locations where services produced and used are common. The supply demand for calculated reflect status districts or counties based on flows. replacement cost methods provide necessary technical supports calculation funds. realigning funds service-benefiting areas service-providing not only identifies beneficiaries suppliers...

Abstract Given the increasing attention to climate change and rising CO 2 (CCRC) in global carbon cycle, we remain unclear about how China's unprecedented land use/cover (LUCC) budget has been affected by CCRC recent decades. Here, combined remotely sensed (LUC) datasets Biome‐BGCMuSo model address this issue setting different scenarios. We found that LUCC led sink increase approximately 104.24 ± 46.52 Tg C without considering during 1990–2020. Carbon sinks contributed afforestation (374.97...

Abstract The development of sequence decomposition techniques in recent years has facilitated the wide use decomposition-based prediction models hydrological forecasting. However, usually overall (OD) sampling technique to extract samples. Some studies have shown that OD causes abnormally “high” performance owing utilization future information, and this cannot be applied practice. Several researchers also proposed novel techniques, such as semi-stepwise (SSD), fully stepwise (FSD),...

The relative contributions of different factors to the variation in surface runoff have been broadly quantified. However, little attention has paid how these changed over time. We analyzed changes during 1980–2010 six subbasins mountainous region Haihe River Basin, one most serious water shortage regions China, and identified climate (precipitation temperature) land-use decrease. There was a decreasing tendency all subbasins, four which had an abrupt change point around 1998. Comparing...

Dynamic monitoring of forest ecosystem quality is necessary for restoration program evaluation but remains challenging very large-scale programs. Current methods employ regional indicators that compare the status targeted forests with benchmarks from remnant old-growth communities, however data availability usually limits application available to small scales. We constructed an improved framework, integrating site classification selection and local community delimitation, quantify map using...

Abstract The impact of climate change, rising CO 2 , land-use/land-cover change and land management on the carbon cycle in terrestrial ecosystems has been widely reported. However, only rarely have studies conducted to clarify sink contributed by ecological restoration projects (ERPs). To better understand ERPs, we took Beijing–Tianjin Sand Source Control Project zone as an example set up different scenarios distinguish confounding effects these factors regional budget based a remote sensing...

Maintaining or increasing water retention in ecosystems (WRE) can reduce floods and increase resource provision. However, few studies have taken the effect of spatial information vegetation structure into consideration when assessing effects land use/land cover (LULC) change on WRE. In this study, we integrated remotely sensed leaf area index (LAI) ecosystem process-based Biome-BGC model to analyse impact LULC WRE Beijing between 2000 2015. Our results show that volume increased by...

Runoff is the key driving factor of Ganjiang River ecosystem. Human activities such as reservoir construction have greatly changed state runoff. In order to analyze influence Reservoir on hydrological regime, following paper based daily precipitation data 53 rainfall stations in Basin from 1959 2016, and runoff three Dongbei, Ji’an, Waizhou 2016. The Mann–Kendall test (MK) was used trend Basin. Sliding t-Test (ST) determine abrupt change time flood season within typical cross-sections upper,...

Landscape change is an important aspect of coastal ecological conservation and has essential influence on the sustainable development economy. With remoting-sensing (RS) images between 2000, 2005, 2010, 2015, using geographic information system (GIS) technologies, we examined ecosystem spatial changes in Bohai zone. Results showed that wetlands, mainly constituted by reservoirs/ponds, were dominant landscape types. The urban largest area increment fastest growth rate from 2000 to 2015....

Ecological benefits provided by ecosystem assets play an important role in improving human wellbeing. However, there are few feasible methods to combine data on the quantity and quality of describe their state trend. Here, we developed a new remote-sensing-based indicator synthesizing asset for effective assessment at regional or national scale. The includes typological index (TEAI) (e.g., forest index) integrated (IEAI). TEAI IEAI can be used assess trend specific set ecosystems,...

Previous research rarely identified the synergistic effects of climate change and human activities on hydrological regimes, thus leading to an incomplete attribution regime changes. To address this issue, paper presents a complete approach for accurately quantifying these impacts. The framework integrates various methodologies, including runoff abrupt point judgment method distinguishing pre- post-impact periods, Soil Water Assessment Tool (SWAT) is used isolate processes influenced solely...

Roads have diverse influences on surrounding biodiversity, especially birds. Here, we evaluated the ecological of a highway avian diversity in Erka Wetland Reserve (Inner Mongolia, China) to guide future road construction projects. and plant surveys were conducted along 51 strips spread over nine transects with different habitat matrixes (including degraded grassland habitat). Nineteen bird species identified, which 84% breeding. Alaudidae was dominant genus, is typical, guild. Bayesian...

The intermittent ozone (O3) exposure of crops to alternating high and low concentrations is common in fields, but its impact on crop production has not been thoroughly investigated. In this study, two widely planted O3-sensitive crops, winter wheat soybean, were intermittently exposed elevated O3 open-top chambers. results showed that the soybean yields significantly decreased with (AOT40, cumulative hourly concentration above 40 ppb) (p < 0.001). relative yield losses 0.99% per AOT40 for...

Soil loss prevention is an important ecosystem service for protecting human and environmental health. Using spatiotemporal climate data of the Eastern Gobi Steppe, a region missing from previous studies Mongolian wind-based soil erosion, we implemented Revised Wind Erosion Equation (RWEQ) model to estimate loss. A replicable pipeline was developed perform these computations, made available openly. estimated on monthly basis analyze seasonal variations. The results show that annual total 61 ×...
