In the context of the era of carbon peaking and carbon neutrality,clarifying the emission patterns of non-CO_(2)Greenhouse Gas(GHG)from agricultural sources is of practical significance to China’s implementation of greenhouse gas emission reduction policies.The Intergovernmental Panel on Climate Change(IPCC)coefficient method was used to calculate non-CO_(2)GHG emissions from agricultural sources in 122 counties in Hunan Province,China,from 2010 to 2020,and the spatiotemporal evolution characteristics of emission intensity were analyzed.The Stochastic Impacts by Regression on Population,Affluence,and Technology(STRIPAT)model forecasted the prospective evolution of non-CO_(2)GHG emissions from agricultural sources at the county level under various scenarios from 2030 to 2050.The results demonstrated a general decline in non-CO_(2)GHG emissions from agricultural sources within the study area,with 75.41%of counties exhibiting a reduction in emissions.Geographically,emissions were higher in the Dongting Lake area and central Hengyang.The emission intensity per unit of agricultural added value and the intensity per unit of agricultural land area showed an overall downward trend.Spatially,the emission intensity per unit of farmland area in a few counties(cities,districts)in southern Hunan was still relatively high.By forecasting the non-CO_(2)GHG emissions from agricultural sources,the majority of counties(cities and districts)demonstrated a gradual decline in emissions,suggesting that agricultural production had the potential to reduce emissions in the future,while also facing certain pressure to reduce emissions.It is recommended that Hunan Province formulate agricultural carbon emission reduction policies that take regional development differences into account.This would provide a reference for future agricultural carbon emission reduction research in the whole country. 展开更多

Garnet is a primary mineral in skarn deposits and plays a significant role in recording copious mineralization and metallogenic information.This study systematically investigates the geochemistry and geochronology of garnet and zircon in the Dafang Au-Pb-Zn-Ag deposit,which represents prominent gold mineralization in southern Hunan,China.Garnet samples with distinct zoning patterns and compositional variations were identified using various analytical techniques,including Backscattered Electron(BSE)imaging,Cathodoluminescence(CL)response,textural characterization,and analysis of rare-earth elements(REE),major contents,and trace element compositions.The garnet was dated U-Pb dating,which yielded a lower intercept age of 161.06±1.93 Ma.This age is older than the underlying granodiorite porphyry,which has a concordia age of 155.13±0.95 Ma determined by zircon U-Pb dating.These results suggest that the gold mineralization may be related to the concealed granite.Two groups of garnet changed from depleted Al garnet to enriched Al garnet,and the rare earth element(REE)patterns of these groups were converted from light REE(LREE)-enriched and heavy REE(HREE)-depleted with positive europium(Eu)anomalies to medium REE(MREE)-enriched from core to rim zoning.The different REE patterns of garnet in various zones may be attributed to changes in the fluid environment and late superposition alteration.The development of distal skarn in the southern Hunan could be a significant indicator for identifying gold mineralization. 展开更多

The Yueguang gold deposit is located in Fengjia,Xinhua County,Hunan Province,South China.It represents a recently discovered small-scale gold deposit situated in the southwestern region of the Jiangnan Orogenic Belt,west of the Baimashan granitic batholith.In order to discern the characteristics of the ore-formingfluids,the underlying mineralization processes,and establish a foundation for the origin of the Yueguang gold depositfluid inclusion micro-thermometry,as well as quartz hydrogen and oxygen isotope analysis,have been carried out on samples obtained from various stages of mineralization.The hydrothermal miner-alization stages within the Yueguang gold deposit can be categorized into three stages:(i)the barren,pre-ore quartz-pyrite stage(Stage Ⅰ),the quartz-pyrite-gold stage(Stage Ⅱ),and the post-ore quartz-carbonate stage(Stage Ⅲ),with the second stage being the main mineralization stage.Thefluid inclusions identified in samples from the main min-eralization stage can predominantly be described with the NaCl–H_(2)O and CO_(2)–NaCl–H_(2)O systems.These inclusions display homogenization temperatures ranging from 158.8 to 334.9℃,and thefluid salinity ranges from 0.3%to 4.0%(wt.%NaCl equiv.).Laser Raman spectroscopy analysis of individual inclusions further reveals the presence of gas-phases such as CO_(2),CH_(4),and N_(2).Isotopic analysis indicatesδ^(18)Ofluid values ranging from 3.95 to 6.7‰ and δDH_(2)O values ranging from-71.9 to-55.7‰.These results indi-cate that the ore-formingfluid of the Yueguang gold deposit belongs to metamorphic hydrothermalfluids of middle-low temperature and low salinity.In the process of ore formation,gold is transported in the form of Au(HS)2-complexes,with gold deposition being driven byfluid immiscibility.Therefore,the Yueguang gold deposit is categorized as an orogenic gold deposit dominated by metamorphic hydrother-malfluid.It may become a new target for gold exploration in the Baimashan region,central Hunan Province. 展开更多

The literary circle in Hunan regions during the late Qing Dynasty underwent an innovative transformation,and the creation of literary works was exceptionally prosperous.The emergence of this literary phenomenon was undoubtedly inseparable from the impetus provided by the Hunan Army Group.However,upon a close examination of its origin and development,it can be discerned that since the mid-Qing Dynasty,numerous scholars in Hunan had already been engaged in the exploration and practice of the concepts of literary creation.Among them,Huang Benji’s Du wen-Bi de was a specialized literary work concentrating on literary composition.It possessed a complete system and novel viewpoints,embodying the distinctive literary perspective of Hunan scholars.Nevertheless,it has not been deeply explored.Through an analysis of the innovative aspects of the literary theory in Du wen-Bi de and its influence on Confucian classics,this study examines the guiding role of this literary work on the literary creation in the Hunan regions during the late Qing Dynasty and its theoretical value in literary thought. 展开更多
