The development of green agriculture is an effective way to realize the sustainable agriculture, which great significance for guaranteeing national food security, improving supply ability agricultural products, promoting healthy cultivated land, and realizing development. Since 18th National Congress Communist Party China, China has proposed establishment a green-development-oriented support system, intends reverse worsening ecological environment; however, in 2019, input chemical fertilizer...

The practice of straw returning to agricultural fields (SRF) affects crop yields and greenhouse gas (GHG) emissions. However, the responses GHG emissions vary significantly due diverse climatic conditions, soil field management practices. In this study, we conducted a meta-analysis assess effects SRF on yield from staple crops in China. Our results indicate that average increment three is 13.00% with SRF. Moreover, decreased N2O compared those without regions 800–1200 mm MAP, SOC > 20 g...

This study examines the health resource networks across China’s 31 provinces and cities (excluding Hong Kong, Macao, Taiwan) between 2012 2021. We construct an evaluation system for resources using entropy weight method analyze structural evolution of network through a complex perspective. Furthermore, spatial econometric model is employed to investigate impact positions on resident health. Our findings show that communication nodes in increased initially then decreased, with core regions...

Exploring the spatiotemporal evolution and driving forces for green transition of cultivated land (GTCL) has become an important part deepening research on use transition, significant implications addressing environmental issues agriculture development. This study took cities in Henan province, main grain-producing area central China, as objects, established evaluation system GTCL based subsystems spatial, functional, mode transition. The entropy weight method spatial autocorrelation model...

Land resources are essential natural and strategic economic for human survival development. However, improper use has brought unprecedented pressure challenges to the ecosystem. Therefore, assessment analysis of land ecological security status identification diagnosis obstacles affecting helpful avoid problems caused by at source provide a theoretical basis sustainable construction civilization in China. Based on data from 2006 2020, this study constructed risk-evaluation index system...

Abstract Many plant leaves appear red in the autumn, and many papers have focused on environmental factors role of anthocyanin this process. However few examined substances that are induced during We hypothesised excess sugar accumulation directly induces under autumn conditions. Using two methods (restricting phloem movement exogenous sucrose feeding), we found both surplus photosynthate could induce biosynthesis, corresponding to up‐regulation several enzymes involved biosynthesis...

Urban form plays a critical role in shaping the spatial differentiation of land surface temperature (LST). However, limited research has investigated underlying driving forces and interactions multidimensional urban form, specifically considering two-dimensional (2D) use three-dimensional (3D) buildings, on LST. Furthermore, their multi-scale outcomes remain unclear. Taking main area Wuhan City as an example, total nine indicators—the proportion administration (PA), commercial (PB),...

Cycloalkanes pose a tremendous environmental risk due to their high concentration in petroleum hydrocarbons and hazardous effects organisms. Numerous studies have documented the biodegradation of acyclic alkanes aromatic hydrocarbons. However, insufficient attention has been paid on microbial degradation cycloalkanes, which might be closely linked psychrophilic microbes derived from low-temperature habitats. Here we show that endemic methylcyclohexane (MCH, an abundant cycloalkane species...

Abstract The phylogeography of common and widespread species helps to elucidate the history local flora vegetation. In this study, we selected C otinus coggygria , a widely distributed in China's warm‐temperate zone. One chloroplast DNA (cp ) region ecological niche modelling were used examine phylogeographic pattern C. . cp data revealed two groups (Southern Northern) corresponding geographic regions. Divergence time analyses that divergence occurred at approximately 147,000 years before...

It is vital to conduct urban ecosystem service evaluations and demarcate ecological management zoning preserve regional security the spatial optimization of functions. This study assessed examined distribution characteristics supply demand five typical services in Zhengzhou their matching pattern. Based on Maslow’s hierarchy needs, was demarcated guide The results showed that most goods were generally provided west south city. High-value areas mainly found center. There a definite circle...

Cyclic alkanes (c-alkanes) are toxic compounds that abundant in subsurface oil reservoirs and spilled condensate; hence, their environmental risk is significant. Although numerous studies have focused on the decomposition of other compound classes, e.g., acyclic aromatic hydrocarbons, very little known about biodegradation c-alkanes marine environment. Here, we enriched methylcyclohexane (MCH)-degrading bacteria derived from cold bottom water (10–20 °C) China's marginal seas summer...

With the rapid development of urbanization, China is facing problems, such as uncoordinated regional development, imbalanced land space and ecological environment pollution. This poses a huge threat to sustainable China’s economy society. Therefore, there an urgent need determine how coordinate relationship between exploitation, economic (SEE) urban areas. In this study, taking Henan Province example, long time-series data (2000–2020) were used, at city scale. Then, we developed logical...

In order to reuse waste wool, two transition metal ions, Fe 3+ and Cu 2+ , were coordinated with it prepare a series of metal–wool complexes as new heterogeneous Fenton photocatalysts for the degradation typical azo dye, CI Reactive Red 195, in aqueous solution. The effect initial ion concentration temperature on reaction was investigated. Furthermore, catalytic performance resulting evaluated respect dye decoloration efficiency at different pH levels under visible irradiation. results...

The original intention of the tripartite rural land entitlement system was to activate farmland management rights and improve efficiency element allocation. However, information asymmetry is prevalent in a market with imperfect competition. We analyzed key factors affecting transfer transactions structural equation model using survey data from farmers five major grain-producing counties Henan province, China. purpose our study investigate how these contribute avoidance “lemon market”...

Increasing pollution has significantly threatened the Antarctic ecosystem. The contamination of hydrocarbons drawn a considerable amount attention owing to their toxicity, recalcitrance, and persistence. Considering Treaty, only indigenous species are allowed bioremediate contaminated environment. However, knowledge ecological role, physiology, function, genomics endemic hydrocarbon consumers is still limited. Here, we investigated dynamics phenanthrene-consuming communities derived from...

SummaryAs the major colour pigments in plants, anthocyanins play a positive photoprotective role plant resistance to abiotic stress. In this work, variations anthocyanin concentration were determined leaves of Begonia semperflorens growing under high light (HL; 900 ?mol m-2 s-1) or low temperature (LT; 15°C day/6°C night) conditions. Partial cDNA sequences four structural genes associated with biosynthesis isolated from leaves. These encoded phenylalanine ammonia-lyase (BsPAL), chalcone...

Scientific quantitative measurement of the coupling relationship between urban population (UP) and land (UL) is conducive to promoting intensive use, coordinated human–land development, new urbanization development. This research proposed an improved model polar coordinates study spatiotemporal characteristics UP UL at prefecture-level city scale in China from 2010 2020. The results include following: (1) growth rate China’s cities was higher than that UP. per capita (PUL) always within...
