Study on design of Linxia brick carving products based on shape grammar
No full textIn view of the problems such as the single type of cultural derivative products of Linxia brick carving and the weak cultural attraction, we carried out the application research of Linxia brick carving culture by using shape grammar. Firstly, we collected and combed the materials of brick carving culture in Linxia by means of literature research and field investigation. Then, we determined the target product, analyzed the product form and emotional demand, construct the reference product form database, screen the brick carving pattern through the matching of the product emotional demand, obtained the characteristic lines of the brick carving pattern by the way of the type spectrum analysis, and established the typical form factor database of brick carving; Finally, taking some lines in the typical form factor database as the initial shape, we combined them with the lines in the reference product form database. According to the shape grammar deduction rules, the scheme was generated, the best scheme was selected and further refined. Studies have shown that the use of shape grammar for product design can enhance the cultural connotation of products, promote cultural heritage, and effectively guide the design of Linxia brick carving products

DataSheet1_Lacustrine Sediments Bacterial Community Structure Vertical Succession of the Linxia Basin, NE Tibetan Plateau: Significance for Paleoenvironment Reconstruction.docx
No full textThe study on sediments in the marginal basins of the Tibetan Plateau is of great significance for global climate change. The geological information of the Linxia Basin has been intensely investigated; however, the profiles of the microbial communities in this basin remain largely unknown. Here, based on the 16S rRNA high-throughput sequencing method, the bacterial community structure vertical succession is studied with different thicknesses of sedimentary samples. The bacterial community with a total of 1,729,658 paired reads distributed within 1,042 phylogenetic amplicon sequence variants (ASVs) from twenty sediments, and three surrounding soil samples were sequenced. First, high-throughput sequencing results highlight the surrounding soil sample bacterial community structures were significantly different from those recovered from the sediment samples. In addition, as observed in the PCoA and PERMANOVA, there is a dramatic change shift event of the community structure at M311. Our data suggest that shifts in relative abundances of the abundant taxa (˃1%) and the significant variations in the diversity of bacterial community implied community structure responses to changes in different sedimentary layers. Predicted community function changes demonstrate that the sediment bacterial community aerobic chemoheterotrophy has been significantly increased, and we believe that the possible influence of the lithofacies changes from the anaerobic system to the aerobic environment, possibly accompanied by the significant uplift of the plateau that has previously been associated with enhanced aridity in Central Asia at ∼8 Ma. Taken together, these results illustrate the potential for the microbial community as a biological indicator in sediment ecosystems to reconstruct paleoenvironments.</p

Descriptive grammar of the Bao'an language - comparative perspectives in the Gansu-Qinghai linguistic area
No full textLa complexité et la diversité des langues de l’aire linguistique du Gansu-Qinghai suscitent de plus en plus l’intérêt de linguistes. Les langues de cette zone géographique appartiennent typologiquement aux trois domaines qui sont “altaïque”, bodique et sinitique. Le bao’an, une des langues minoritaires de cette zone, est parlé par les locuteurs du Tongren de la province du Qinghai et par les locuteurs du Jishishan de la province du Gansu. Il est en contact étroit avec les langues qui l’environnent : le bao’an du Qinghai est particulièrement en lien avec le tibétain du Tongren, alors que le bao’an du Gansu se retrouve plus en contact avec le mandarin local. Dans cette étude, nous avons proposé une description de la langue bao'an du Gansu, sous une perspective comparative dans l'aire linguistique du Gansu-Qinghai. Le problème du contact entre le bao'an et le parler du Linxia est également abordé dans notre description, du fait d'un grand nombre d'emprunts ainsi que de caractéristiques syntaxiques partagées entre les deux langues. Par rapport aux autres langues mongoliques de l'aire linguistique du Gansu-Qinghai, le bao'an du Gansu n'a pas fait l'objet de recherches suffisantes. L'un des objectifs de ce travail est de compléter les données sur le bao'an du Gansu en fournissant des analyses en termes de phonologie, de morphologie (nominale et verbale) ainsi que de syntaxe.The complexity and diversity of the languages of the Gansu-Qinghai linguistic area are increasingly attracting the interest of linguists. The languages of this geographical area belong typologically to the three domains: Altaic, Bodic, and Sinitic. Bao'an, one of the minority languages of this area, is spoken by Tongren speakers in Qinghai province and Jishishan speakers in Gansu province. It is in close contact with the surrounding languages: Qinghai Bao'an is particularly related to Tongren Tibetan, while Gansu Bao'an is more in contact with local Mandarin. In this study, we have proposed a description of the Gansu Bao'an language from a comparative perspective within the Gansu-Qinghai linguistic area. The problem of contact between Bao'an and Linxia dialect is also addressed in our description, due to a large number of borrowings as well as syntactic features shared between the two languages. Compared to other Mongolian languages in the Gansu-Qinghai linguistic area, Gansu Bao'an has not been sufficiently researched. One of the aims of this work is to complete the data on Gansu Bao'an by providing analyses in terms of phonology, morphology (nominal and verbal), and syntax
Quality suitability regionalization analysis of Angelica sinensis in Gansu, China.
No full textThe genus Angelica encompasses 80 species worldwide. Among them, only Angelica sinensis is widely used in China and Japan. To explore the quality and geographical distribution of A. sinensis, we collected 1,530 plants from Gansu Province and analyzed them for their contents of chlorogenic acid (CA), ferulic acid (FA), senkyunolide I(SI), senkyunolide A(SA), senkyunolide H (SH), coniferyl ferulate (CF), ligustilide (LI), and butenyl phthalide (BP) using UPLC. We also assessed the relationship between the ecological environment and quality of A. sinensis through maximum entropy modeling and a geographical information system. The habitat suitability distribution demonstrated that the most influential ecological factors for the growth of A. sinensis were altitude, precipitation during March, May, and December, precipitation during the wettest month, and the soil pH. The most suitable areas for cultivation are concentrated to the south of Gansu Province, including Linxia Hui Autonomous Prefecture, Dingxi City, Tianshui City, south of Wuwei City, east of Gannan Tibetan Autonomous Prefecture, north of Longnan City, and northwest of Pingliang City. The quality suitability regionalization analysis divulged that the most influential ecological factors for the index components of A. sinensis were the altitude, sunshine, rainfall, temperature, and soil pH. The highest quality A. sinensis grow in Dingxi City, Tangchang, Lixian, and Wen counties in Longnan City, Wushan County in Tianshui City, Lintan, Zhouqu, and Zhuoni counties in Gannan Tibetan Autonomous Prefecture, Kangle and Linxia counties in Linxia Hui Autonomous Prefecture. The experiment yielded highly accurate results (accuracy of 0.955), suggesting that the results were consistent with the actual distribution of A. sinensis in Gansu. The inferences of this research will naturally draw the attention of the authorities in the fields of natural resources and agriculture departments and provide a scientific basis for the rational selection of A. sinensis cultivation areas
Intertwined model of syntactic borrowing in the Gansu-Qinghai linguistic area
No full textThis paper studies two grammatical cases in the Gansu-Qinghai linguistic area. Accusative-dative, a syncretic case largely attested in Sinitic languages, is also found in Bao’an and Tu, even if in a very limited use. The Sinitic languages have acquired this syncretic case marking through pattern reduplication due to language contact, while Bao’an and Tu have this innovation owing to the internal mechanisms of their language. The second phenomenon concerns possessor constructions in which the subject-possessor must be marked by a dative case. This marking is seen in all non-Sinitic languages in the Gansu-Qinghai linguistic area and has begun to appear in Sinitic languages. Multiple paths for borrowing between and inside languages in this area present an intertwined model of language borrowing. Linxia City and its closest counties should be the spreading center of these new syntactic devices, and Muslim populations speaking different languages may form a spreading net
The Variation Characteristics of Mesoscale Convection System in a Severe Convective Torrential Rain over the Northeast Slope of the Qinghai-Xizang Plateau
No full textA rare torrential rain occurred in the northern Linxia and western Lanzhou on the northeast side of the Qinghai-Xizang Plateau from 20:00 （Beijing Time， the same as after） on 22 to 08:00 on 23 July， 2018， with the maximum total rainfall of 176.8 mm and the maximum hourly rainfall of 61.6 mm.Based on the data of satellite， CINRAD， automatic weather stations and reanalysis data， the occurrence and development characteristics of the mesoscale convective system （MCS） causing severe convective rainstorm and its trigger mechanisms were analyzed.The results show that： （1） Severe convective rainstorms occurred under the favorable configuration of a warm and humid air flow of the periphery of Western Pacific subtropical high combined with multiple zonal fluctuations driving cold air eastward.The environment of high temperature and humidity created favorable conditions for the occurrence of severe convective rainstorm.（2） Two MCS developed successively caused severe convective rainstorms in the northern Linxia and western Lanzhou.The isolated convective cloud clusters strengthened and merged into the first stage of MCS.The MCS spreading to the southwest and the clouds moving from the Gannan plateau to the northeast gradually merged into the MCS of the second stage in the heavy rain area.Heavy rainfall over 10 mm·（10min）-1 occurred at the edge of cloud cluster in the upwind direction， and the heavy rainfall is closely related to the development of convective cloud clusters.（3） During the severe convective rainstorm， the strong echo in the first stage had obvious backward propagation characteristics.The strong convective cell had a high frequency of impact on the heavy rainstorm area， and the significant "Train Effect" moving from south to north caused intermittent heavy rainfall lasting more than 6 hours.（4） Mesoscale wind speed pulsations in the boundary layer， surface convergence line and special terrain are the main factors that triggered the occurrence and development of mesoscale convective systems.The formation， maintenance and movement of the surface mesoscale convergence line had a good correspondence with the location of heavy rainfall
Spatiotemporal Heterogeneity of Temperature and Precipitation in Complex Terrain along the Northeastern Margin of the Tibetan Plateau
No full textThe study of climate element distribution models under complex terrain conditions is a popular topic in the field of GIS application in climatology, especially in plateau areas with a complex topography and scarce meteorological station information. In this paper, the spatial and temporal heterogeneity of temperature and precipitation at the northeastern edge of the Tibetan Plateau was analyzed by taking the northeastern edge of the plateau as the study area and constructing a topographic spatial statistical model using 47 meteorological stations and digital elevation models from 1981 to 2010. The following conclusions were drawn from the study: (1) The ME of the temperature distribution model for each month is below 0.9 °C; the maximum ME of the precipitation distribution model for each month is −5.808 mm in July, and the precipitation distribution model has similar error characteristics with the temperature distribution model, which can reflect the horizontal zone distribution pattern of meteorological data and can clearly show the changes of temperature and precipitation as the altitude increases. (2) The spatial distribution pattern of temperature is as follows: the temperature in the study area gradually increases from the southwest to the northeast, with Zhouqu County in Linxia Prefecture and Gannan Prefecture as the main high-temperature areas; the spatial distribution of precipitation is as follows: the precipitation in the southwest of the study area is significantly higher than that in the north, and the precipitation in Linxia Prefecture is significantly lower than that in Gannan Prefecture. (3) The temporal distribution pattern of the temperature distribution model is as follows: the overall temperature in the study area is at its lowest level in January, and the maximum temperature is only 2.6 °C, until July, when the maximum temperature rises to 24.2 °C and then gradually starts to decline; the spatial distribution of precipitation is as follows: the precipitation in the study area gradually rises from January, and the maximum precipitation rises to July and then starts to decline, and in December the precipitation falls to the lowest level. The temporal distribution characteristics of the precipitation distribution model are similar to those of the air temperature model, with obvious hydrothermal synchronization characteristics
