The ecological problems caused by dry and wet deposition of atmospheric nitrogen have been widespread concern in the world. In this study, depositions were monitored plant growing season coastal zone Yellow River Delta (YRD) using automatic sampling equipment. results showed that<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="M1"><mml:mrow><mml:msup><mml:mrow><mml:msub><mml:mrow><mml:mtext>SO</mml:mtext></mml:mrow><mml:mrow><mml:mn...

Ecological engineering is a widely used strategy to address environmental degradation and enhance human well-being. A quantitative assessment of the impacts ecological on ecosystem services (ESs) prerequisite for designing inclusive sustainable programs. In order strengthen national security, Chinese government has implemented world’s largest project since 1999, Grain Green Program (GFGP). We professional model evaluate key ESs in Lvliang City. Scenario analysis was quantify contribution...

Forestry eco-engineering programs in China occupy 721.77 × 104 km2, among which plantations have a pivotal role protecting the fragile ecological environment. Reforestation understory is often ignored because of simple vertical structure. The importance light has been discovered. However, how other ecology factors (e.g., soil properties and geographical factors) influence composition stratification remain unclear. In this study, we investigated effects on environmental black locust...

Abstract Widespread and rapid land‐use changes have changed the ecosystem structure threatened soil functions. Soil enzymes are important driving force sensitive indicators for ecological function. However, effect of afforestation on enzyme activity relative importance influencing factors (plants, soil, structure, nutrition) still inconclusive, especially in early stage afforestation. Here, enzymatic activities five types plantations (18 years old) natural grassland topsoil (0–20 cm)...

Abstract. Soil carbon sequestration plays an essential role in mitigating CO2 increases and the subsequently global greenhouse effect. The storages dynamics of soil organic (SOC) 0–30 cm depth different landscape types including beaches, reservoir pond, reed wetland, forest bush farmland, building land, bare land (severe saline land) salt field modern Yellow River Delta (YRD), were studied based on data regional survey laboratory analysis. classified by interpretation remote sensing images...

Artemisia sacrorum communities with different growth years were selected to analyse soil nutrient characteristics, the variation in microbial properties, and their relationships loess hilly region. The results showed that an increase number of years, biomass carbon nitrogen contents as well phosphatase urease activities initially decreased then increased A. communities. organic carbon, nitrogen, total respiration rate increasing trend reached a maximum at age (a) 37. available phosphorus...

Abstract Plant diversity is an important link between forest ecosystems' structural composition and functional processes. The simple of young plantations weakening the ecological function restored ecosystems in arid regions. drivers plant dissimilarity remain unclear, especially early restoration stage. To fill gap knowledge differences species ecosystems, to reveal influencing factors similar numbers with different compositional structures, based on species' presence‐absence, abundance,...

Soil carbon and nitrogen are central to soil quality function. Changes in land use types the stability of aggregates significantly affect accumulation related C N. Enzyme activity plays an important role N utilization by participating transformation nitrogen. To explain effects on aggregates, enzyme activities N, we selected samples five northern China: natural forest (NF), artificial (AF), shrubland (SL), meadow (MD), farmland (FL). In topsoil (0-10 cm) subtopsoil (10-20 cm), particle size...

Accumulation of vegetation biomass is a crucial process for carbon fixation in the early stage afforestation and primary driving force subsequent ecological functions. Accurately assessing storage allocation elements plantations essential their management estimating sink capacity. However, current knowledge patterns within plant organs at community level limited. To clarify distribution level, we measured five typical loess hilly-gully region. We assessed main drivers element accumulation by...

We explored the distribution characteristics and influencing factors of understory species in Robinia pseudoacacia plantation Wuqi, Ansai, Mizhi, Yichuan other places, combination with niche breadth, soil, altitude environmental factors. analyzed response mechanism to factor provide a scientific basis for mana-gement R. loess hilly region. The results showed that broadly distributed were Setaria viridis, Heteropappus altaicus, Artemisia scoparia, Poa sphondylodes, leucophylla, Ixeris...

Abstract Aims In order to better understand the changes in potential carbon sequestration capacity of forest soil after invasion broad-leaved trees into pure larch plantations, effects broadleaf tree on aggregate stability and by organic active components were studied. Methods northern China, Larix principis-rupprechtii plantations invaded Betula platyphylla at various degrees with same site conditions selected ( had a mixed degree 0.2 0.4, respectively). ANOVA, correlation analysis,...

Ongoing warming and frequent extreme rainfall are endangering hydrological functioning in reforested ecologically vulnerable areas. The forest floor plays an important role water conservation; however, knowledge of under climate change remains limited, particularly with respect to retention its temperature sensitivity restored ecosystems. Here, we investigated sampled litter topsoil from three pure plantations, two mixed plantations one natural grassland on the hilly gullied Loess Plateau....

Afforestation, an important measure for ecological restoration, has been implemented all over the world, but fragile ecosystem structures and climate change endanger its functions. One major obstacle to optimizing function quantifying characterizing a complex structure. Here, structure functions of six types land - use restoration were investigated in hilly-gully region Loess Plateau, China. In total, 44 factors from canopy, understory soil determined. We constructed related network...
