Terrestrial ecosystem carbon storage (TECS) could significantly affect the concentration of atmospheric CO2, which is critical for climate change prediction. Along these lines, Integrated Valuation Ecosystem Services and Trade-offs model was employed to determine TECS Hainan Island (HN) from 2015 2050 accurately. Besides, Future Land-use Simulation combined with natural anthropogenic factors used forecast land-use types 2025 in HN by considering different Shared-socioeconomic...
<title>Abstract</title> <bold>Background and Aims:</bold> Highly weathered tropical forests are widely recognized as nitrogen (N)-rich phosphorus (P)-poor, the input of nutrienteffects soil carbon (C) cycling storage in these ecosystems. In topsoil, short-term nutrient additionmay not only effect organic C (SOC) pools directly, but also impact conversion process indirectly through altering microbial use efficiency (CUE). However, effects addition on accumulation mechanisms remain unclear....
It has been widely recognized that replacing chemical fertilizers with organic (organic substitution) could significantly increase the long-term productivity of land and potentially enhance resilience to climate change. Nevertheless, there is limited information on accurate monitoring soil greenhouse gas (GHG) fluxes at different levels substitution in rubber plantations. Before estimation GHG can be made, it important investigate diurnal variations suitable sampling times. In this study,...
In this study, β-cyclodextrin (β-CD) functionalized graphene quantum dots (GQDs) was employed to augment the array of chiral recognition sites, thereby enhancing affinity GQDs/β-CD composite for imprinting molecules and realizing heightened selectivity. The incorporation into synthesis molecularly imprinted polymers (MIPs), synergizing with host-guest inclusion properties β-CD abundant carboxyl groups GQDs, enhanced capacity MIPs materials. Consequently, a novel MIPs/(GQDs/β-CD) sensor...
The intensification of global climate change has made the study greenhouse gas (GHG) emissions increasingly important. To gain a deeper understanding emission characteristics and driving factors nitrous oxide (N2O), carbon dioxide (CO2), methane (CH4) from rubber plantation soils, this conducted 16-month continuous observation in Danzhou, Hainan, employing static chamber method for monthly sampling measurement GHG while analyzing soil’s physical chemical properties. results indicated that...
As global climate change intensifies, arid land ecosystems face increasing challenges. Vegetation, a key indicator of variation, is highly responsive to meteorological factors such as temperature (Tem), precipitation (Pre), and soil moisture (SM). Understanding how fractional vegetation cover (FVC) responds in regions critical for mitigating its impacts. This study utilizes MOD13Q1-NDVI data from 2000 2022, alongside corresponding Tem, Pre, SM data, explore the dynamics underlying mechanisms...
Understanding the water use efficiency (WUE) of rubber plantations to seasonal fluctuations is critical for understanding water, energy, and carbon cycle in tropical regions. In this study, we examine exchange heat fluxes between land atmosphere plantation ecosystems during monsoon drought seasons, employing data collected from eddy covariance towers. Further attribution analysis demonstrates that drought-induced alterations are predominantly governed by changes surface resistance (positive...
Overuse of chemical nitrogen (N) fertilizers leads to N leaching and soil degradation. Replacing with organic can enhance nutrition, reduce loss, improve productivity. However, the effects combining on components transformation remain unclear. A 12-year field study included four treatments: no fertilizer (CK), alone (CF), 50% combined co-composted (CFM), composted (CFMC) fertilizer. The results showed that CFM CFMC significantly enhanced SOC, TN, LFON, DON, NH4+-N, MIN levels compared CF....
Data on particulate matter, gaseous pollutants, and AQI values from three cities (Haikou, Sanya, Danzhou) between January 2018 December 2022 were obtained in order to analyze the spatiotemporal distribution characteristics of air pollution, correlation pollutants with meteorological conditions, potential sources Hainan Island. The distribution’s demonstrated that annual mean concentrations SO2, NO2, CO, O3, PM10 PM2.5 4.34 ± 1.11 μg m−3, 9.87 1.87 0.51 0.06 mg 73.04 6.36 27.31 3.63 14.01...
Understanding the impact of long-term partial substitution chemical nitrogen fertilizer with organic fertilizers (partial substitution) on soil components, mineralization, and availability is necessary to foresee (N) dynamics. The present study was conducted a field experiment investigate effect 12 years application nutrient concentrations, enzymatic activities, N mineralization in rubber plantation. Treatments included: unfertilized as control (CK), 100% recommended dose (CF), integrated...
Abstract Background and Aims : Soil microbial carbon use efficiency (CUE) directly impacts the balance between atmosphere soil. Atmospheric N deposition may alter soil CUE due to effect of nitrogen availability on metabolism. However, how affects forest ecosystem is still not clear. Methods: This study examined responses short-term addition treatments in top (0–10 cm) deep (60–80 soils from two tropical forests Hainan, southern China. Additionally, a meta-analysis was conducted reveal global...
