This study focuses on the master of arts education in higher education institutions in Guangxi Zhuang Autonomous Region of China,explores the path of integrating Guangxi Zhuang’s intangible cultural heritage with the teaching of master of arts,and puts forward the teaching mode of“thinking guidance-autonomous judgement-program construction.”A theoretical model of innovative transformation of intangible cultural heritage is also summarized.Through the development of this study,it is expected to further enrich the practical teaching mechanism of master of arts education in Chinese universities and form a master of arts teaching model with strong local cultural characteristics.At the same time,the teaching reform based on the integration of Guangxi Zhuang’s intangible cultural heritage and master of arts education also has strong practical significance for promoting the inheritance and innovation of Chinese intangible cultural heritage,promoting the development of cultural and creative industries,and serving the economic and social development of Guangxi.

Late Oligocene fossil acorns and nuts of Quercus section Cyclobalanopsis from the Nanning Basin,Guangxi,South China

Quercus is the largest genus within the Fagaceae and has a rich fossil record.Most of the fossil material is attributed to the subgenus Quercus based on leaves,pollen or rarely acorns and nuts.Fossil records of Q.section Cyclobalanopsis characterized by ring-cupped acorns are relatively few and especially those described based on nuts are scant.In this study,we described four new species of Quercus section Cyclobalanopsis based on mummified acorns and nuts:Q.paleodisciformis X.Y.Liu et J.H.Jin sp.nov.,Q.paleohui X.Y.Liu et J.H.Jin sp.nov.,Q.nanningensis X.Y.Liu et J.H.Jin sp.nov.and Q.yongningensis X.Y.Liu et J.H.Jin sp.nov.These species closely resemble the extant species Q.disciformis,Q.hui,Q.kerrii,and Q.dinghuensis.The occurrence of Q.section Cyclobalanopsis in the Oligocene stratum of Guangxi,South China,suggests that the section has diversified within its extant distribution center since the Oligocene.By combining records from other areas,we propose that the section first appeared in the middle Eocene of East Asia(Sino-Japan),has diversified in situ with a few elements scattering into West Asia and southern Europe since the Oligocene and Pliocene,respectively,and finally became restricted in East Asia since the Pleistocene.This indicates that the section originated and diversified in East Asia,before spreading into West Asia no later than the Oligocene and into southern Europe by the Pliocene.Subsequently it disappeared from South Europe and West Asia due to the appearance of the(summer dry)Mediterranean climate and widespread cooling during the Pleistocene.

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.

A Basal Titanosauriform from the Early Cretaceous of Guangxi, China

Based on a partial postcranial skeleton collected from the Lower Cretaceous Napai Formation of Guangxi, China, we erect a new sauropod taxon, Fusuisaurus zhaoi gen. et sp. nov. The holotype specimen consists of the left ilium, left pubis, anterior caudals, most of the dorsal ribs and distal end of the left femur. Fusuisaurus zhaoi is diagnosed by a unique combination of character states among the known sauropods. It displays several synapomorphies of Titanosauriformes but lacks many derived features seen in other titanosauriforms, suggesting that the new taxon represents the basalmost known titanosauriform and providing new evidence that Titanosauriformes originated from Asia. A size comparison suggests that Fusuisaurus zhaoi is among the largest Early Cretaceous sauropods, providing an important addition to the Early Cretaceous Chinese sauropod diversity.

A New Eusauropod Dinosaur from the Lower Cretaceous of Guangxi Province,Southern China

A new sauropod dinosaur,Liubangosaurus hei gen.et sp.nov.,is erected based on a specimen represented by five articulated middle-caudal dorsal vertebrae,which was discovered in the Lower Cretaceous Napai Formation of Guangxi Province,southern China.This new taxon is diagnosed by a unique combination of derived features：prezygapophysis closely contacts with parapophysis,with the prdl and prpl absent;presence of cavity on the dorsal surface of the diapophysis;neural spine very low,with its distal end level with that of diapophysis;distal end of the neural spine strongly expanded laterally to form a platform;marked fossa formed between the infradiapophyseal lamina and the parapophysis;broad,flat area of featureless bone on lateral surface of neural arch;vertically directed infradiapophyseal lamina expands or bifurcates ventrally to form a inverted ＂Y＂;highly positioned parapophyses large and tear-drop in shape.The discovery of this new taxon increases the diversity of sauropods in China during the Early Cretaceous.

A New Species of Odorrana Inhabiting Complete Darkness in a Karst Cave in Guangxi, China

A new species of the genusOdorrana is described from a completely dark karst cave of northeastern Guangxi, southern China. The new species,Odorranalipuensissp. nov., can be distinguished from its congeners by a combination of the following characters： medium size （SVL： 40.7–47.7 mm in males, 51.1–55.4 mm in females）;tips of all but ifrst ifnger expanded with circummarginal grooves; smooth, grass-green dorsum with irregular brown mottling; pineal body invisible; throat to upper abdomen with gray mottling; dorsal surfaces of limbs with brown bands; dorsolateral fold absent; tiny spinules on lateral body, temporal region, and anterior and posterior edge of tympanum;white nuptial pad present on ifnger I; males lacking vocal sacs; females having creamy yellow eggs, without black poles. Uncorrected sequence divergences betweenO.lipuensissp. nov. and all homologous 16S rRNA sequences ofOdorrana available on GenBank is equal to or greater than 4.9%. Currently, the new species is only known from the type locality.

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.

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.

Devonian Bivalve Faunas, Life-habits, and Biodiversity Changes in Guangxi, South China

Objective The Devonian bivalves are well developed, highly diversified and widely distributed in Guangxi. However, they have not been well studied previously, although several papers have dealt with it. Meanwhile, the biodiversity change of bivalves which is one of the most important benthos during Devonian in South China has not been studied yet. The aim of present project is focused on the study of systematic palaeontology, the life-habits, of Devonian bivalves of Guangxi.

Triassic Transgressive-Regressive Sequences in Guizhou-Guangxi Region, South China

Seven third-order transgressive-regressive sequences are recognized in the Early Triassic -Early Carnian stratigraghc succession of Guizhou-Guangxi region, South China. Based on currently available ages by the correlation of conodont ammonites and bivalve faunas, these sequences range approximately from 1.0 Ma to 5.6 Ma, with the average of 3 Ma. They occur largely in the Griesbachian-Dienerian, Smithian,uppermost Smithian-lowermost Anisian, Lower Anisian, Middle Anisian, Upper Anisian-Upper Ladinian and the uppermost Ladinian-Lower Carnian respectively, and can be grouped into three second-order transgressive-regressive supersequences. A relative sea level curve is established from the sequence stratigraghic analysis. Transgressive-regressive sequences,bounded by transgressive surfaces and the correlatable unconformities, are real unconformity-bounded units of lower rank. Each sequence comprises transgressive, highstand and regressive systems tracts, and can be easily correlated with the depositional sequence.

Dinoflagellate cysts in recent marine sediment from Guangxi, China

Total of 33 species of dinoflagellate cysts were discovered from surface sediment in the sea region of Guangxi, among them 12 cyst types (Diplopsalopsis sp. 1, D. sp. 2, D. sp. 3, Cochlodinium sp., Protoperidinium sp. 1, P. sp. 2, P. compressum, Scrippsiella sp. 1, S. sp. 2, Alexandrium sp. 1, A. sp. 2, A. sp. 3) were first reported from the South China Sea. And one cyst type (Cochlodinium sp.) was first reported in the world. Scrippsiella trochoidea is the dominant species in this area, accounting for 45% of all the cysts. There are 2 cysts of toxic dinoflagellate (Alexandrium tamarensis and Gymnodinium catenatum) But there is no relationship between cyst number and grain size distribution.

A Megatheropod Tooth from the Early Cretaceous of Fusui, Guangxi, Southern China

A nearly complete right maxillary or left dentary tooth（NHMG 10858） from the Lower Cretaceous Xinlong Formation of the Napai Basin, Fusui County, Guangxi, southern China, is described. The tooth is large in size, with a CBL of 37 mm. Given the geological age and its crown morphology, including the size, it is most likely that the tooth belongs to a carcharodontosaurid. The recovered specimen represents one of the largest theropod teeth hitherto reported from the Early Cretaceous of Asia.

Buxus Leaves from the Oligocene of Guangxi, China and Their Biogeographical Significance

The present paper reports two new species of Buxus from the Oligocene Ningming Formation of Guangxi, South China, on the basis of several compressed fossil leaves.Buxus ningmingensis sp.nov.is characterized by an elliptic to ovate shape; pinnate venation with marginal secondary, long hairs on the adaxial side of the midvein base; and amphistomatic, anomocytic stomata with a prominent outer ring.All of these characteristics suggest a closest affinity to the living Buxus microphylla subsp.sinica.Another new species identified as Buxus preaustro-yunnanensis sp.nov.is characterized by the diagnostic formation of its admedially branched tertiaries, the trunks of which are often strongly thickened by sclereides.This species is most similar to the extant Buxus austroyunnanensis.The co-occurrence of Buxus ningmingensis sp.nov.and Buxus preaustro-yunnanensis sp.nov.suggests that these two Buxus lived during the Oligocene under a warm, tropical to subtropical climate, similar to the current climate of Ningming.Our findings provide the earliest fossil evidence of Buxus leaves with detailed illustrations of leaf architectural and cuticular features.The occurrence of these two species indicates that Buxus began to diversify in Guangxi no later than the Oligocene.

Preliminary Investigation on the Main Fungal Diseases of Sugarcane in Guangxi Province of China

[ Objective ] The purpose was to understand species and occurrence status of major fugal diseases in sugarcane cultivation areas of Guangxi in China, so as to provide scientific references for integrated control against sugarcane diseases. [ Method] Species and occurrence degrees of major fugal diseases in sugarcane cultivation areas of Guangxi were investigated through randomized surveys, farmer interviews, literature references and location investigations from 2009 to 2011. Diseased sugarcane samples were collected and their species were identified through pathogen isolated culture and other relevant methods. [ Result] Thirteen spe- cies of fungal diseases were identified in the survey, including pineapple disease [ Thielaviopsis paradoxa （ de Seynes ） V. Hohnel ], smut （ Ustilago scitaminea Sydow）, top rot disease （Fusarium moniliforme Sheldon）, rust （Puccinia melanocephala H. ＆ P. Syd. ）, leaf scald disease （Stagonospora sacchari Lo et Ling）, red rot disease （Colletotrichumfalcatum Went）, zonate spot disease （Phyllosticta saccharicola P. Henn. ）, leaf red spot disease [ Pellicularia sasakii （Shirai） Ito], white rash disease （Elsinoe sacchari L. ）, eye spot [Helminthosporium sacchari （Breda de Haan） Butler], yellow spot [Mycovellosiella koepkei （kruger） Deighton], brown stripe [Bipolaris stenospilum （Drechs.） Shoem. ] and brown spot （Cercospora longipes Butler）. Smut, rust, top rot, and pineapple disease were the most rampantly detrimental to quality and yield of sugarcane. [ Conclusion] Smut is the most serious sugarcane disease; it is urgent to breed sugarcane varieties with high resistance and excellent agronomic characters to replace current sugarcane varieties susceptible to diseases.

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.

Geochemistry of Permian Mafic Igneous Rocks from the Napo-Qinzhou Tectonic Belt in Southwest Guangxi, Southwest China: Implications for Arc-Back Arc Basin Magmatic Evolution

The Napo-Qinzhou Tectonic Belt （NQTB） lies at the junction of the Yangtze, Cathaysia and Indochina （North Vietnam） Blocks, which is composed of five major lithotectonic subunits： the Qinzhou-Fangcheng Suture Zone （QFSZ）, the Shiwandashan Basin （SB）, the Pingxiang-Nanning Suture Zone （PNSZ）, the Damingshan Block （DB） and the Babu-Lingma Suture Zone （BLSZ）. On the basis of geochemical compositions, the Permian mafic igneous rocks can be divided into three distinct groups： （1） mafic igneous rocks （Group 1） from the Longjing region in the PNSZ and Hurun region in the BLSZ, which are characterized by intermediate Ti, P and Zr with low Ni and Cr contents; （2） mafic igneous rocks （Group 2） from the Naxiao and Chongzuo region in the DB, characterized by low-intermediate Ti, P and Zr with high Ni and Cr concentrations; and （3） mafic igneous rocks （Group 3） from the Siming region in the Jingxi carbonate platform of the northwestern margin of the NQTB, with intermediate-high Ti, P and Zr and low Ni and Cr contents. The Group 1 rocks yield a weighted mean 206 Pb/ 238 U age of 250.5±2.8 Ma and are geochemically similar to basalts occurring in back-arc basin settings. The Group 2 rocks exhibit geochemical features to those basalts in island arcs, whereas the Group 3 rocks show geochemical similarity to that of ocean island basalts. All three groups are characterized by relatively low ε Nd （t） values （-2.61 to ＋1.10） and high initial 87 Sr/ 86 Sr isotopic ratios （0.705309-0.707434）, indicating that they were derived from a subduction-modified lithospheric mantle and experienced assimilation, fractional crystallization, and crustal contamination or mixing during magmatic evolution. Accordingly, we propose the existence of an arc-back arc basin system that developed along the NQTB at the border of SW Guangxi Province （SW China） and northern Vietnam, and it was formed by continued northwestward subduction of the Cathaysian （or Yunkai） Block under the Yangtze Block, and northeastward subduction of the Indochina Block beneath the Yangtze Block during Permian time.

Analysis on construction of the Supply Chain and Brand of Guangxi Characteristic Economic Agricultural Products——A Case Study of Guilin,China

Firstly,it is briefly introduced that Guangxi characteristic economic agricultural products are currently characterized by typical regional features and strong competitiveness.Then,Guilin is taken as an example,the problems existing in constructing the supply chain and brand of Guilin characteristic economic agricultural products are pointed out after the analysis of its current situations,the problems include weak agricultural production infrastructure,weak deep products processing capacity,low modernization level of storage and transportation as well as short of fixed marketing channels;meanwhile,brand construction faces the problems of little top brands and few differentiated products.Finally,some measures are proposed to solve these problems from the perspectives of establishing the management idea of agricultural products supply chain and enhancing the awareness to protect agricultural products brand,it is also suggested that these measures be extended to the whole Guangxi autonomous region in order to explore the way of the development of Guangxi characteristic agriculture.

A new species of Leptobrachella(Anura:Megophryidae)from central Guangxi,China

A new species of the genus Leptobrachella,Leptobrachella damingshanensis sp.nov.is described from central Guangxi,China,based on morphological,molecular,and acoustic data.Phylogenetic analyses using a 16S rRNA gene fragment indicated that the new species formed an independent clade close to L.nahangensis and L.nyx.However,the new species differs from all known congeners based on a combination of the following characters:medium size(snout-vent length(SVL)33.6–34.4 mm in males);pair of distinct jacinth humeral glands on proximal thigh area;rough dorsal skin with sparse jacinth tubercles and several short longitudinal ridges;creamy white ventral surface with small,creamy white glands on throat,chest,belly,and ventral surfaces of thighs,becoming more concentrated near lateral margin;webbing and lateral fringes absent on fingers,toes with rudimentary webbing and narrow lateral fringes;flanks with small irregular black spots;iris bicolored,upper half copper,fading to silver in lower half.Uncorrected p-distances were greater than 4.7%between Leptobrachella damingshanensis sp.nov.and all homologous DNA sequences available for the 16S rRNA gene.The new species is only known to occur in the Damingshan National Nature Reserve,where it inhabits montane evergreen forests between 1000–1200 m a.s.l.
