Recreation Service Supply–Demand Relationship and Driving Mechanism Analysis in the Three Gorges Reservoir Area, China
Clarifying the relationship between the supply and demand of recreation service not only enhances our comprehension of how cultural ecosystem services impact human well‐being, but also offers a theoretical foundation and scientific basis for developing regional landscape management strategies. However, previous studies have predominantly focused on static or short‐term spatial heterogeneity analyses of recreation service, or have evaluated recrea…
Impacts of Urbanization on Economic Development and Ecological Protection of the Wuhan City Circle, China
The conflict between economic development and ecological protection in land use (LU) has been a significant and widely discussed topic. The city circle concept has been proposed to promote economic growth through its strong agglomeration effect. It contains the core city and its surrounding area, and economic activities and ecosystems are highly intertwined within this geographic unit. Meanwhile, population, industry, and infrastructure are often…
Impacts of environmental and socioeconomic factors on gross ecosystem product of the Three Gorges reservoir area, China
Environmental and socioeconomic drivers would alter landscapes, bringing various effects with different directions and magnitudes. Demonstrating these driving effects is key to relieving the conflicts between territorial vegetation restoration and regional economic growth. However, the relationship between ecological protection and economic development due to landscape dynamics has not been systematically demonstrated as environment is difficult …
Critical needs to close monitoring gaps in pan-tropical wetland CH 4 emissions
Global wetlands are the largest and most uncertain natural source of atmospheric methane (CH 4 ). The FLUXNET-CH 4 synthesis initiative has established a global network of flux tower infrastructure, offering valuable data products and fostering a dedicated community for the measurement and analysis of methane flux data. Existing studies using the FLUXNET-CH 4 Community Product v1.0 have provided invaluable insights into the drivers of ecosystem-t…
Effects of vegetation restoration on soil nutrients, plant diversity, and its spatiotemporal heterogeneity in a desert–oasis ecotone
Vegetation restoration has been proposed as an effective measure for rehabilitating degraded land and slowing desertification in arid regions. However, the spatial variation in soil quality and plant diversity following vegetation restoration remains unclear. This study was designed to explore soil nutrient dynamics and how soil nutrients affect plant diversity and spatial heterogeneity after shrub restoration. We assessed the effect of Haloxylon…

Nitrogen -addition accelerates phosphorus cycling and changes phosphorus use strategy in a subtropical Moso bamboo forest
Ecosystem-level effects of increasing atmospheric nitrogen (N) deposition on the phosphorus (P) cycle and P use strategy are poorly understood. Here, we conducted a seven year N-addition experiment to comprehensively evaluate the effects of N deposition on P limitation, cycling, and use strategy in a subtropical Moso bamboo forest. N addition significantly increased foliar litterfall by 4.7%–21.7% and subsequent P return to the soil by 49.0%–70.1…
The Global Methane Budget 2000–2017
Understanding and quantifying the global methane (CH4) budget is important for assessing realistic pathways to mitigate climate change. Atmospheric emissions and concentrations of CH4 continue to increase, making CH4 the second most important human-influenced greenhouse gas in terms of climate forcing, after carbon dioxide (CO2). The relative importance of CH4 compared to CO2 depends on its shorter atmospheric lifetime, stronger warming potential…
Biochar amendment decreases soil microbial biomass and increases bacterial diversity in Moso bamboo ( Phyllostachys edulis ) plantations under simulated nitrogen deposition
Biochar amendment has been proposed as a strategy to improve acidic soils after overuse of nitrogen fertilizers. However, little is known of the role of biochar in soil microbial biomass carbon (MBC) and bacterial community structure and diversity after soil acidification induced by nitrogen (N) deposition. Using high-throughput sequencing of the 16S rRNA gene, we determined the effects of biochar amendment (BC0, 0 t bamboo biochar ha ^−1 ; BC20,…
Global wetland contribution to 2000–2012 atmospheric methane growth rate dynamics
Increasing atmospheric methane (CH 4 ) concentrations have contributed to approximately 20% of anthropogenic climate change. Despite the importance of CH 4 as a greenhouse gas, its atmospheric growth rate and dynamics over the past two decades, which include a stabilization period (1999–2006), followed by renewed growth starting in 2007, remain poorly understood. We provide an updated estimate of CH 4 emissions from wetlands, the largest natural …

Past and future carbon sequestration benefits of China’s grain for green program
Biomass offsets little or none of permafrost carbon release from soils, streams, and wildfire
As the permafrost region warms, its large organic carbon pool will be increasingly vulnerable to decomposition, combustion, and hydrologic export. Models predict that some portion of this release will be offset by increased production of Arctic and boreal biomass; however, the lack of robust estimates of net carbon balance increases the risk of further overshooting international emissions targets. Precise empirical or model-based assessments of t…
Disentangling climatic and anthropogenic controls on global terrestrial evapotranspiration trends
We examined natural and anthropogenic controls on terrestrial evapotranspiration (ET) changes from 1982 to 2010 using multiple estimates from remote sensing-based datasets and process-oriented land surface models. A significant increasing trend of ET in each hemisphere was consistently revealed by observationally-constrained data and multi-model ensembles that considered historic natural and anthropogenic drivers. The climate impacts were simulat…

Poverty and Gender Oriented Vulnerabilities to Food and Water Scarcity in Touroua, Cameroon
This paper analyses the vulnerability of different income groups and gender to food and water shortages caused by deforestation and based on population perceptions. Data was obtained through the random administration of 200 questionnaires in the study site. Data was analyzed using the Statistical Package for the Social Sciences (SPSS) version 19 in which Pearson correlation was used. The results show that there is an inverse relationship between …
The role of technology and policy in mitigating regional nitrogen pollution
Human activity greatly influences nitrogen (N) pollution in urbanized and adjacent areas. We comprehensively studied the N cycling in an urban-rural complex system, the Greater Hangzhou Area (GHA) in southeastern China. Our results indicated that subsurface N accumulation doubled, riverine N export tripled and atmospheric N pollutants increased 2.5 times within the GHA from 1980-2004. Agriculture was the largest N pollution source to air and wate…

Changes in Forest Biomass Carbon Storage in China Between 1949 and 1998
The location and mechanisms responsible for the carbon sink in northern mid-latitude lands are uncertain. Here, we used an improved estimation method of forest biomass and a 50-year national forest resource inventory in China to estimate changes in the storage of living biomass between 1949 and 1998. Our results suggest that Chinese forests released about 0.68 petagram of carbon between 1949 and 1980, for an annual emission rate of 0.022 petagram…
