Evaluation and Quantitative Attribution Analysis of Water Yield Services in the Peak-cluster Depression Basins in Southwest of Guangxi,China

Karst environmental issues have become one of the hot spots in contemporary international geological research. The same problem of water shortage is one of the hot spots of global concern. The peak-cluster depression basins in southwest of Guangxi is an important water connotation and ecological barrier areas in the Pearl River Basin of China. Thus, studying the spatial and temporal variations and the influencing factors of its water yield services is critical to achieve the sustainable development of water resources and ecological environmental protection in this region. As such, this paper uses the Integrated Valuation of Ecosystem Services and Tradeoffs(InVEST) model to assess the spatial and temporal variabilities of water yield services and its trends in the peak-cluster depression basins in southwest of Guangxi from 2000 to 2020. This work also integrates precipitation(Pre), reference evapotranspiration(ET), temperature(Tem), digital elevation model(DEM), slope, normalized difference vegetation index(NDVI), land use/land cover(LULC) and soil type to reveal the main factors that influence water yield services with the help of Geodetector. Results show that: 1) in time scale,the total annual water yield in the study area show a fluctuating and increasing trend from 2000 to 2020, with a growth rate of 7.3753 × 10^(8)m^(3)/yr, and its multi-year average water yield was 538.07 mm;2) in spatial pattern, with high yield areas mainly distributed in the south of the study area(mainly including Shangsi County, Pingxiang City, Ningming County, Longzhou County and Jingxi County), and low yield areas mainly distributed in Baise City and Nanning City;3) the dominant factor of water yield within karst and non-karst landforms is not necessarily controlled by precipitation, and the explanation degree of DEM factors in karst areas is significantly higher than that in non-karst areas;4) amongst the climatic factors, Pre, ET and Tem are dominant in the spatial pattern of region water yield capacity. among which Pre has the highest explanatory power for the spatial heterogeneity of annual water production, with q values above0.8, and each driver showed a significant interaction on the spatial distribution of water yield, with Pre exhibiting the strongest interaction with LULC.

Epidemiological Investigation and Analysis of Major Viral Diseases of Pig Farms in Guangxi from 2019 to 2022

In order to understand the epidemic characteristics of major viral infectious diseases of pig farms in Guangxi from 2019 to 2022,the PCR and RT-PCR methods were applied to detect the pathogens of 1046 samples suspected CSFV(swine fever virus),PRRSV(porcine reproductive and respiratory syndrome virus),PCV-2(porcine circovirus virus type 2),PCV-3(porcine circovirus virus type 3),PRV(pseudorabies virus),TGEV(transmissible gastroeneritis of pigs virus),PEDV(porcine epidemic diarrhea virus)and PoRV(porcine rotavirus)infections in recent four years,and epidemiological analysis was carried out.The results showed that positive rates of CSFV,PRRSV,PCV-2,PCV-3,PRV,TGEV,PEDV and PoRV were 3.91%(21/537),20.46%(143/699),29.90%(116/388),16.10%(81/503),27.75%(121/436),2.10%(8/381),28.50%(61/214)and 13.74%(18/131).The infection rates of PCV-2 and PEDV were decreasing year by year,while the infection rate of TGEV was increasing year by year.In single infection,the infection rates of PRV and PEDV were higher,with an average infection rate of 13.53%and 18.22%.In the mixed infection,the infection rate of PRRSV and PCV-2 was the highest,with an average infection rate of 11.34%.The second mixed infection rate was PEDV and PoRV,and the average infection rate was 8.05%.The infection rate of PCV-3 and PEDV was higher in spring,with 18.80%and 40.00%respectively.The infection rate of PRRSV,PCV-2,PRV,TGEV and PoRV was higher in winter,with 24.40%,40.57%,37.30%,3.23%and 19.44%respectively.The results showed that PRRSV,PCV-2,PRV and PEDV were the main viral diseases with serious damage to pig farms in Guangxi.It was necessary to strengthen pathogen monitoring and improve comprehensive prevention and control ability,in order to reduce the incidence of disease and economic losses.

A Comprehensive Review Analyzing Half a Century of Wang Yangming’s Contributions to Governance in Guangxi

Wang Yangming was a prominent thinker and politician with significant national influence during the Ming Dynasty.He has been a key subject of study in the realms of China’s ideological history,academic history,and political history.His travels to various regions have been the subject of valuable research.While the contribution of Wang Yangming in Guangxi has historically been less extensive compared to his contributions in places such as Zhejiang,Guizhou,and Jiangxi,it has shown gradual improvement over the past 50 years.Particularly,there has been an expanding and deepening exploration of the wisdom and impact he left during his governance of Guangxi.

Indosinian Foreland Fold-and-Thrust Belt Bordering Yunnan and Guangxi, China

Recent discoveries of ophiolites indicate that there must be a Palaeotethyan geosuture zone bordering China and Vietnam, which separates the Vietbac block from the South China subcontinent. The Indosinian foreland fold-and-thrust belt bordering Yunnan and Guangxi provided further evidence for the palaeotethysides. The oceanic crust was subducted southwestwards while the magmatic arc migrated northeastwards, and the continent-arc collision occurred in the Late Triassic with the thrusting being extended towards the north or northeast. The features of thrust-nappe structure are discussed, which proved the continental margin of the Palaeotethyan ocean there to be a complicated one. A face-to-face collision occurred first along the NW-striking segment and then along the ENE-striking segment accompanied by transpression or oblique thrusting occurring along the NW-striking one.

Organic carbon isotope and pollen evidence for mangrove development and response to human activity in Guangxi(Southwest China) over the last 140 years

Mangrove degradation must reduce carbon sequestration in recent years, thereby aggravating global warming.Thus, short-term impacts of human activity on mangrove ecosystems are cause for concern from local governments and scientists. Mangroves sediments can provide detailed records of mangrove species variation in the last one hundred years, based on detailed 210 Pb data. The study traced the history of mangrove development and its response to environmental change over the last 140 years in two mangrove swamps of Guangxi, Southwest China. Average sedimentation rates were calculated to be 0.48 cm/a and 0.56 cm/a in the Yingluo Bay and the Maowei Sea, respectively. Chemical indicators（δ13Corg and C：N） were utilized to trace the contribution of mangrove-derived organic matter（MOM） using a ternary mixing model. Simultaneous use of mangrove pollen can help to supplement some of these limitations in diagenetic/overlap of isotopic signatures. We found that vertical distribution of MOM was consistent with mangrove pollen, which could provide similar information for tracing mangrove ecosystems. Therefore, mangrove development was reconstructed and divided into three stages： flourishing, degradation and re-flourishing/re-degradation period. The significant degradation, found in the period of 1968–1998 and 1907–2007 in the Yingluo Bay and the Maowei Sea, respectively, corresponding to a rapid increase of reclamation area and seawall length, rather than climate change as recorded in the region.

Diagnosis of a Heavy Precipitation Process in Northern Guangxi

[Objective] The aim was to analyze one strong precipitation process in Northern Guangxi from May 27 to 28 in 2010.[Method] By dint of 2.5×2.5 NCEP reanalysis data,physical quantities such as the water vapor flux,pseudo-equivalent temperature,Non-geotropic wet Q vector in one front rainstorm process in north Guangxi from May 27 to 28 in 2010 was expounded.The forecast application of Non-geotropic wet Q vector in rainstorm falling area in Guangxi during early flood period was discussed.[Result] The water vapor in Bay of Bengal transported to Guangxi and formed convergence lifting movement in north Guangxi,which provided favorable water vapor transportation condition for the generation of strong precipitation in north Guangxi.The 850 hPa pseudo-equivalent temperature front (close area) moved southward to the north part of Guangxi.North Guangxi was in pseudo-equivalent temperature area.The highly wet unstable energy of lower layer and the cold air penetrating downward from the middle layer led to potential instability in the lower level established in northern Guangxi,which thus provided certain thermal condition for the strong precipitation process;Northern Guangxi was in the overlap region of the maximum gradient region of contour Qx at 850 hPa and stronger negative areas of ▽Q,which provided favorable dynamic condition for the rainstorm process in northern Guangxi in the future.[Conclusion] The study provided reference in accordance to the forecast of rainstorm.

The Silurian A-Type Granites in Northeastern Guangxi,South China Block:New Evidence of Transition from Compression to Post-orogenic Extension of the Kwangsian Orogen

Objective More and more evidence suggests that the Kwangsian orogen is probably an intraplate orogen, which is one of the few examples of intraplate orogenesis worldwide. However, the initiation time, size and scope of the Kwangsian orogeny have not been determined yet. This study analyzed the Silurian A-type granites in northeastern Guangxi, South China Block, which may provide new evidence for the transition from compression to post- orogenic extension of the Kwangsian orogen.

Timing of the Early Paleozoic Yangtze and Cathysian Convergence： Constraint from U-Pb Geochronology of Hydrothermal Zircons from Mafic Mylonite within the Shoucheng-Piaoli Ductile Shear Zone, Northern Guangxi

Objective The northern Guangxi region is in the southwestern part of the Southern China continent,which is located at the junction of the southwest section of the Early Paleozoic Yangtze block and Cathaysian block.A series of NNE-trending ductile shear zones are developed in this region,and these ductile shear zones are mostly previously suggested boundary faults of the Early Paleozoic Yangtze block and Cathaysian block,such as the Shoucheng–Piaoli ductile shear zone in Northern Guangxi （Meng Yuanku et al., 2016; Zhang Xuefeng et al., 2015）.

New Discovery and Zircon Hf Isotopic Composition of the Early Yanshannian Monzogranite in the Yingyangguan Group of Eastern Guangxi, China

Objective The Yingyangguan Group is widely exposed in the southwestern segment of boundary belt between Yangtze and Cathaysian blocks and is mainly composed of a suit of lower-grade metamorphic marine volcanoclastic- sedimentary rocks （Zhou Hanwen et al., 2002）. Its forming age and petrogenesis are critical for better understanding the orogenic process and relationship of the Yangtze and Cathaysian blocks since the Neoproterozoic. However, few zircon U-Pb ages of samples from the Yingyangguan Group have been reported, which are much debated, such as the metamorphic spilite （819±11 Ma）, keratophyre （415.1±2.1 Ma） and ignimbrite （821.3±3.9 Ma） （Tian Yang et al., 2015 and references in）. In this study, we focus on the new discovered Early Yanshannian monzogranite and its mafic enclaves from the Yingyangguan Group, and conducted zircon U-Pb dating and in-situ Hf isotopic analyses to constrain their petrogenesis.

The proprotein convertase subtilisin/kexin type 9 geneE670G polymorphism and serum lipid levels in the Guangxi Bai Ku Yao and Han populations

Background The association of E670G polymorphism in the proprotein convertase subtilisin/kexin type 9 (PCSK9) gene and serum lipid profiles is inconsistent in dif- ferent ethnic groups.Bai Ku Yao is a special subgroup of the Yao minority in China.The present study was undertaken association of PCSK9 E670G polymorphism and several environmental factors with serum lipid levels in the Guangxi Bai Ku Yao and Han populations.Methods A total of 649 subjects of Bai Ku Yao and 646 participants of Han Chinese were randomly selected from our previous stratified randomized cluster samples.Genotyping of the PCSK9 E670G polymorphism was performed by polymerase chain reaction and restriction fragment length polymorphism combined with gel electrophoresis,and then confirmed by direct sequencing. Results The levels of serum total cholesterol(TC),high-density lipoprotein cholesterol(HDL-C),low-density lipoprotein cholesterol(LDL-C) and apolipoprotein(Apo) AI were lower in Bai Ku Yao than in Han(P【0.01 for all).The frequency of A and G alleles was 98.00%and 2.00%in Bai Ku Yao,and 95.20%and 4.80%in Han(P【0.01);respectively. The frequency of AA,AG and GG genotypes was 95.99%,4.01%and 0%in Bai Ku Yao,and 91.02%, 8.36%and 0.62%in Han(P【0.01);respectively.There were also significant differences in the genotypic and allelic frequencies between n and the ratio of ApoAI to ApoB in Han Chinese but not in Bai Ku Yao were different between the AA and AG/GG genotypes(P【0.05 for all).The G allele carriers had higher serum HDL-C and higher ApoAI to ApoB ratio than the G allele noncarriers.When serum lipid parameters in Han were analyzed according to sex,the G allele carriers had higher serum HDL and ApoAI levels in males (P【0.05),and lower ApoB level and higher ApoAI to ApoB ratio in females(P【0.05 for all).Multiple linear regression analysis showed that serum HDL-C levels were correlated with genotypes in both ethnic groups(P【0.05 each).Serum lipid parameters were also correlated with sex,age,body massindex,alcohol consumption,cigarette smoking,and blood pressure in both ethnic groups(P【0.05-0.001).Conclusions These results suggest that the PCSK9 E670G polymorphism is mainly associated with some serum lipid parameters in the Han population,both gender show different relations to different serum lipid parameters.The G allele carriers might have higher serum lipid profiles than the G allele noncarriers. ormal LDL-C(≤3.20 mmol/L) and high LDL-C subgroups (】 3.20 mmol/L,P【0.01;respectively) in Bai Ku Yao, and between normal ApoB(≤1.14 g/L) and high ApoB subgroups(】 1.14 g/L,P 【 0.01;respectively) in Han.

Association of methylenetetrahydrofolate reductase C677T polymorphism and serum lipid levels in the Guangxi Bai Ku Yao and Han populations

Objectives The association of methylenetetrahy-drofolate reductase(MTHFR) gene polymorphism and serum lipid profiles is still controversial in diverse ethnics.Bai Ku Yao is an isolated subgroup of the Yao minority in China. The aim of the present study was to eveluate the association of MTHFR C677Tpolymorphism and several environmental factors with serum lipid levels in the Guangxi Bai Ku Yao and Han populations.Methods A total of 780 subjects of Bai Ku Yao and 686 participants of Han Chinese were randomly selected from our previous stratified randomized cluster samples.Genotyping of the MTHFR C677T was performed by polymerase chain reaction and restriction fragment length polymorphism combined with gel electrophoresis,and then confirmed by direct sequencing.Results The levels of serum total cholesterol(TC),high-density lipoprotein cholesterol (HDL-C),low-density lipoprotein cholesterol(LDL-C), apolipoprotein(Apo) AI and ApoB were lower in Bai Ku Yao than in Han(P【0.05-0.001).The frequency of C and T alleles was 77.4%and 22.6%in Bai Ku Yao,and 60.9%and 39.1%in Han(P【0.001);respectively.The frequency of CC,CT and TT genotypes was 58.7%,37.3%and 4.0%in Bai Ku Yao,and 32.6%,56.4%and 11.0%in Han(P【 0.001);respectively.The levels of TC and LDL-C in both ethnic groups were significant differences among the three genotypes(P【0.05-0.01).The T allele carriers had higher serum TC and LDL-C levels than the T allele noncarriers. The levels of ApoB in Han were significant differences among the three genotypes(P【0.05).The T allele carriers had higher serum ApoB levels as compared with the T allele noncarriers. The levels of TC,TG and LDL-C in Bai Ku Yao were correlated with genotypes(P【0.05-0.001),whereas the levels of LDL-C in Han were associated with genotypes(P【 0.001).Serum lipid parameters were also correlated with sex, age,body massindex,alcohol consumption,cigarette smoking, and blood pressure in the both ethnic groups.Conclusions The differences in serum TC,TG,LDL-C and ApoB levels between the two ethnic groups might partly result from different genotypic and allelic frequencies of the MTHFR C677Tor differentMTHFR gene-enviromental interactions.

Experimental Study on the Mechanism for the Formation of Sn- bearing Granite in Northern Guangxi

Experimental results have proved that the Xuefengian Sn-bearing biotite granites were formed by remelting and recrystallization of the Proterozoic metamorphic rocks of the Sibao Group at 500× 105-2000× 105 Pa and 750-570℃ and further testified that the F- and B-bear-ing aqueous solution played an important part in decreasing the formation temperature of the rocks. The results tally with the reality of the field geology. The authors have thus brought to light the mechanism for the formation of the Sn-bearing biotite granites and expounded the significance of their formation in the crust dynamics of South China.

Analysis of Karst Tufa from Guangxi, China

The paper presents an analysis of characteristic karst tufa from Guangxi, China, which has not been studied before. A comparison with tufa from Dinaric Karst of Croatia is discussed in view of the C-type climate. The major mineral is calcite. Minor minerals are quartz and dolomite, depending on location. The content of calcium carbonate varies from 65% to 92%, and that of magnesium carbonate from 0.03% to 1.77%. Among other elements, the most abundant are Fe, from 0.02% to 1.50%, and Ti, from 0.15% to 0.27%. Many other trace elements (V, Cr, Mn, Ni, Cu, Zn, As, Se, Br, Rb, Sr, Y, Zr, Hg and Pb) are also present. Specific activity of radionuclides 40K, 232Th, 137Cs, 226Ra and 238U varies from sample to sample. Concentration of U in tufa is close to that reported for sedimentary carbonate. Low concentration of 137Cs indicates that this part of the world was not exposed to nuclear explosions. The concentration of 226Ra is the highest in Mashan County. The ratio 238U/226Ra (0.21-0.71) in tufa from Mashan County is significantly lower than the theoretical value of 1. In 5 of the 11 studied samples, stable isotopes δ13C and δ18O were analyzed. They were dated by means of the 14C method. One tufa sample originated in the Pleistocene and the others in the Holocene. Because all of the tufa samples contain traces of Na and K, and K < Na, the tufa from Guangxi belong to the CO2-outgassing 'N' type according to the classification of Liu and He (1994).

Bio-organic Geochemical Characteristics of Gold Deposits in Northwestern Guangxi and Their Metallogenetic Significance

The gold deposits of Triassic period in the northwestern Guangxi are all located in the marine, fine -grained ,fragmental rock series containing organic matter ,i.e .the distribution districts of black rock series . The fine-grained gold deposits occur in organic matter -bearing C, D,E,or D,E divisions of the classical Bouma sequences. The evolution degree of organic matters through oil window stage reached the over -mature degree. Both the bio-sources of the organic matters and the distribution of gold in the organic matters disclose the close association between gold , living beings and organic matters . The thermal evolution of organic matters led to the gold to be activized . migrated and enriched , and finally formed gold deposits in the fault belt and crushed zone of black rock series .

Study on Design Rainstorm Profile in Liuzhou City Based on Pilgrim &Cordery Method

Liuzhou City is located in Guangxi Zhuang Autonomous Region of China. It has a warm and rainy climate and belongs to the middle subtropical monsoon climate. It is a rainstorm and flood-prone area. The work of flood drainage and waterlogging prevention is very important. The “minute to minute” rainfall process data of Liuzhou National Meteorological Observation Station from 1975 to 2014 and the Pilgrim & Cordery method were used to estimate the short-time design rainstorm profile of Liuzhou City, and the profiles of the rainfall lasting for 30, 60, 90, 120, 150, and 180 min were obtained. The research shows that the same rain duration and different recurrence period conditions are consistent with the rainstorm profile. The rainfall duration of 30, 60, 90, 120, and 180 min generally shows single-peak rainstorm profile, and the rainfall duration of 150 min shows double-peak rainstorm profile. Most peaks of each short-time design rainstorm profile are at or ahead of the 1/3 part of the entire rainfall process. During the same recurrence period, the rainfall in peak period fluctuated with the increase of the duration, and the intensity of rainfall increased with the prolonging of the recurrence period.
