Research on Dong Zhongshu’s Five Elements Thought

Dong Zhongshu reordered the Five Elements,that is,wood,fire,soil,gold,and water,and believed that this was the order given by heaven and could not be changed.The Five Elements are related to each other.The relationship between the two adjacent to each other is the relationship of generation and father-son;the relationship between the two separated is reciprocal.The soil is in the middle,and the soil has the noblest morality.Therefore,Dong Zhongshu’s view of“Filial piety is natural”originates from the father-son relationship between the Five Elements and the nobility of soil virtue.According to the Five Elements,the state management should set up five kinds of official posts in order to achieve the purpose of interdependence,mutual restriction,balance,and promotion.Dong Zhongshu matched the Five Elements with the four seasons,and believed that each of the Five Elements had its own virtues,and thus extended it to the virtues of the monarch.Dong Zhongshu linked the Five Elements with the five things,thinking that the five things of the king will affect the Five Elements;the five things are appearance,speech,sight,listening,thinking,which is given by heaven.To govern the country and the people the king must have five important cultivations.

Study on Tourism Development and Community Participation in Villages of the Minorities ——With the Dong Village in Zhaoxing,Southeast Guizhou Autonomous Prefecture of Miao and Dong Nationalities,China

Based on basic theories of community participation in tourism development,questionnaires were designed for the field investigation in one of the largest Dong Villages in China,the Dong village in Zhaoxing.Community participation in tourism development of the Dong Village was analyzed from the perspectives of residents' participation in decision-making and management,reception and catering services,group performance,making and selling ethnic artworks,protection of village tourist resources and environment.And meanwhile,problems were pointed out as "still maintaining in the early stage of its tourism development,fewer opportunities for its residents participating in tourism development,resource protection being divorced from tourism benefits and so on",on the basis of which corresponding solutions were offered as "expanding the field of participation,improving the level of participation,increasing benefits of local residents;insisting on the principle of "not participating intentionally is the best way of their participation,guaranteeing economic compensation for rural residents;enhancing infrastructure construction;establishing a museum of folk-custom materials;creating a favorable atmosphere of folk cultures;enhancing cooperation with its neighboring villages in tourism development,and creating a "local industrial chain";establishing a research center of cultural tourism development of the Dong Minority.

Farming Ritual and Festival Folk Custom of Dong Ethnic Minority Group

In order to pray for harvest and express gratitude, Dong ethnic arranged sacrifices of farming in accordance with periodicity of rice production and its requirements to festivals and calendar. Meanwhile, New Year, Pray in Spring and Return in Autumn not only play significant roles in agricultural production, but also evolve to farming holidays which are enriched with more social connotations. Centered on husbandry and production, some folklore that is rich in local color has been formed in Dong society. The writer introduced some farming ritual of Dong ethnic group, such as, sowing, Kai Yang Men, Rain-praying, Chang Xin, reaping and Lunar New Year, summarized their belief in the land worship, festival ritual, ancestor ritual and ceres ritual. It is concluded that sacrifice is a production-related folklore, which is formed by repeated operation and constant practice. Some taboos were also prohibited in agricultural sacrifice because people were not able to change the unfavorable reality of farming with their insufficient experience and knowledge; however, they resorted to witchcraft for the purpose of harvest. It is believed that the activity of sacrifice will also be kept in the life of Dong ethnic group due to their dependency on agriculture and the land.

HOLOCENE SALINE SEDIMENTARY RECORD IN TIBETAN DONG CO(LAKE) AND ITS SIGNIFICANCE ON PALAEOCLIMATE

Based on the sedimentary characteristics study of Holocene borax\|bearing mirabilite beds of Dong Co(lake) two sections, DZ01 and DZ02, in the center of North\|Tibetan Plateau,combined with dating of 14 C, applied theory and method of comparative salinology, it is determined that the palaeoclimate framework of Dong Co during early\|middle Holocene, and reckoned the range of the temperature variation. Furthermore, after completing regional analogue, discovered that the palaeoclimate environment is fully comparative and consistent with the synchronous lake\|water retreating trace of Zhaduixiong spits in Zabuye Lake basin, with palaeoclimate changes recorded by pollen in adjacent Zabuye Lake, with Holocene plaeoclimate environment indicated by drilling\|hole in Bangong Co,with palaeoclimate significance traced by δ 18 O value in Qinghai Lake and Siling Co and with the palaeoclimate framework during the 5th Level Arid (Salinization) Extension Period of Quaternary arid center of Western China.

Discovery of Borax-bearing Mirabilite Beds in Dong Co, Northern Tibet, and Its Palaeoclimatic Significance

The authors investigated lacustrine chemical sediments on terrace-I of DongCo-a salt lake in the interior of the northern Tibetan Plateau and firstly discovered borax and acomplete sedimentary section with five pure mirabilite beds. According to the sedimentarycharacteristics of rhythmic layering, palaeotemperatures for the formation of the cold-phasemineral-mirabilite-at the profiles and ^(14)C dating, the authors applied the theory and method ofcomparative salinology in the study of the history of the palaeoclimate and palaeoenvironment ofDong Co in the early and middle Holocene and drew the conclusion that the salt lake had experiencedthe following climatic evolution: the warm and moist stage (>8470 a HP and possibly to 10500 aHP)->cold and dry stage (8470-8170 a BP)->warm and moist stage (8170-7590 a BP)->stage of repeatedclimatic oscillations (7590-7400 a BP, alternation of three dry oscillations and three moistoscillations in a generally cold climatic background)->cold and dry stage (7400-6940 a BP)->warm andmoist stage (6940-6620 a BP)->cold and dry stage (6620-6410 a BP)->warm and moist stage (after 6410a HP).

Geochronology of the Dong Tso Ophiolite and the Tectonic Environment

The wedge shaped Dong Tso ophiolitic block is distributed near the transition point from the western to the middle sub-belt of the Bangong-Nujiang suture zone.The ophiolite is characterized by well-developed cumulate rocks that are mainly composed of cumulate and massive gabbros.In the cumulate gabbros,the adcumulate amphiboles are distributed extensively around the plagioclase and residual pyroxene grains; hence,the rocks are named adcumulate amphibole-gabbro.In this study,the formation age of the ophiolite has been estimated to be 166 ± 4 million years （Ma） by the sensitive high-resolution ion microprobe （SHRIMP） Ⅱ U-Pb isotopic analysis of the zircons from the adcumulate amphibole-gabbro; the 40Ar/39Ar plateau age was estimated to be 148.19 ± 1.53 Ma,which should represent the emplacement time of the ophiolite,by isotopic dating of the pure amphibole mineral from the amphibole-schist.Two different suits of volcanic lavas have been recognized in this work.The purple colored pillow basalts have high TiO2 and P2O5 contents,and are rich in light rare earth elements （LREEs）,large-ion lithospheric elements （LILEs） and high-field-strength elements （HFSEs）,the characteristics that are the typical of the oceanic island basalt （OIB）.On the other hand,other massive basaltic andesites of celadon color are poor in MgO; rich in Fe2O3,LREEs,LILEs,and HFSEs; and especially characterized by negative Nb and Ta anomalies,the properties that establish the andesites as continental arc volcanic rocks.It is concluded that hotspots had developed in the old Dong Tso basin,the oceanic basin that had been developing from middle Jurassic （166 Ma） or even before and emplaced northward in late Jurassic （about 148 Ma）.

Effects of Hypobaric Storage on Physiological and Biochemical Changes in Postharvest Dong Jujube Fruit During Cold Storage

Effects of hypobaric storage on physiological and biochemical changes in Dong jujube fruit were investigated. Hypobaric storage significantly delayed the decrease in firmness and maintained content of ascorbic acid, reduced accumulation of ethanol and acetaldehyde in pulp and respiration, inhibited activities of ascorbic acid oxidase and alcohol dehydrogenase and slowed down the rate of ethylene production, but had little effect on flesh browning of the fruit.

Changes of Precipitation Infiltration Recharge in the Circumstances of Coal Mining Subsidence in the Shen-Dong Coal Field,China

Coal mining subsidence is a universal environmental-geological problem in mining areas. By selecting the Shen-Dong coal mining subsidence area as the research field, this paper studies the changes in precipitation infiltration recharge in the circumstances of coal mining subsidence by means of field geological investigation and laboratory simulation experiments, which is expected to provide a scientific basis for eco-environmental restoration in the mining area. The results indicate that at the unstable stage of subsidence, three types of subsidence in the Shen-Dong mining area have positive effects on the precipitation infiltration recharge, and the type of full-thickness bedrock subsidence has the greatest influence. In the stable stage of subsidence, the precipitation infiltration process after long- term drought and the moisture migration in the aeration zone undergo three different stages： evaporation-infiltration before precipitation, infiltration-upward infiltration-infiltration during precipitation and evaporation-infiltration after precipitation. During a heavy rainfall infiltration process, the wetting front movement in fine sand, coarse sand and dualistic structure of fine-coarse sand consists of two stages： the stage of wetting front movement during precipitation, in which the wetting front movement distance has linear relationship with the depth, and the stage of wetting front movement after precipitation, in which the wetting front movement distance has the power function relationship with the depth. The wetting front movement velocity is influenced by the rainfall amount and the lithology in the aeration zone. However, as the depth increases, the movement velocity will decay exponentially.

Evaluating the efficiency of the Dong model in determining fire vulnerability in Iran’s Zagros forests

Recent fires in Iran’s Zagros forests have inflicted heavy,extensive losses to the environment,forests,villages,and forest inhabitants,resulting in a huge financial loss to the country.With the increasing risk of fire and the resulting losses,it has become ever more necessary to design and develop efficient fire control and prediction procedures.The present study utilizes the Dong model to develop a map of areas vulnerable to fire in the Zarivar lake forests as a representative sample of Zagros forests.The model uses as its inputs some of the most significant factors(such as vegetation,physiographic features,and the human component)that affect the fire occurrence and spread.Having assigned weights to each factor based on the model,all maps were overlapped in the ArcMap and then the region was divided into five zones.The results showed that 74%of the region was located in three classes:highly vulnerable,vulnerable,and medially vulnerable.To validate the proposed zoning map it was compared with a map based on real data obtained from previous fires.The results showed that 81%of fire incidents were located in highly vulnerable,vulnerable and medially vulnerable zones.Furthermore,the findings indicated a medium to a high degree of fire vulnerability in Zarivar Lake forests.

The Transition of Cultural Ecology in Beidong District of Guizhou–A Case Study of Tianzhu Community

Beidong minorities living together in Qingshui River valley are deeply influenced by Jing and Chu culture. Their ethnic and traditional culture was developed in the process of collision with foreign culture. In the several great social transformations,their cultural ecology was not imbalanced,but evolved and developed. Through the study on local knowledge of cultural ecology including agricultural production,ancestral hall and local- style dwelling house,full- scale drama and Yang Drama,genealogical system,marriage customs,religious belief,sacrificial rites and funeral rites,it is expected to reveal reasons and rules of transition of Beidong ethnic culture,favorable for correctly understanding cultural connotation and promote cultural and tourism development in ethnic minority areas.

Rural Survey Thoughts and Practice Activities of Dong Shijin

The rural survey movement started in China in the 1920s and 1930s provided a solid support for understanding the rural areas,solving the crisis in rural areas,and saving and revitalizing the rural areas. At that time,various forces at home and abroad devoted themselves to this movement and made remarkable valuable research achievements. Dong Shijin was committed to the prevention and treatment of water and drought disasters and the survey of ' agriculture,rural areas and farmers'. His agronomic thought not only has great academic value in the rural survey movement,but also has practical reference for the implementation of the rural revitalization strategy.

Indigenous Knowledge of Natural Resource Management and Population Control for Dong Ethnic Group in Guizhou Province

Dong ethnic people have rich indigenous knowledge in terms of their daily life and production, which plays an important role in the sustainable development of their village. This paper aims to understand traditional knowledge of Dong ethnic people in resource management and population control, including traditional resource management, traditional medicinal knowledge and village regulations in Zhanli Village in Southeast Guizhou Province. The research methods include key informant interview, group discussion, participant observation and secondary data collect- ing. The results show that Zhanli villagers try their best to utilize indigenous knowledge to manage the natural resources and keep the stable population to make themselves live in a sustainable way. Indigenous knowledge plays an important role in managing their limited natural resources and keeping the population stable under an excellent condition. Zhanli villagers employ indigenous knowledge to manage natural resources and use local herbs to control the population. Village regulation terms significantly influence villagers’ awareness in resource management and birth control. Women play the chief role in employing indigenous knowledge in weaving as well as medicinal knowledge in birth control, and these kinds of knowledge are passed down through the female line. However, the inheritance style of traditional knowledge is decreasing. Indig- enous knowledge plays an important role in the sustainable development of this village, which gives implications for development practices to involve indigenous knowledge to achieve sustainable development.

Environmental factors control and climate change impact on forest type: Dong PraYa Yen-KhaoYai world heritage in Thailand

Climate is a major determinant of global vegetation patterns and has a significant influence on the distribution and structure of forest ecosystems. Dong PraYa Yen-KhaoYai Forest Complex has been a UNESCO natural world heritage site since 2007, but little is known about its plant community. Our study aims to identify each plant community within the world heritage area and calculate its potential for carbon content. We determine both the relationship between forest type and both physio-chemical soil properties and climate change impact. We employed allometric equations to calculate aboveground biomass and both cluster analysis and canonical correspondence analysis (CCA) to examine the relationship between forest type and physiochemical soil properties. An equation for each physical parameter was used to predict the forest model. The climate scenario under A2 and B2 was applied to calculate future predominant forest types. Our results reveal that the forest ecosystems at Tab Lan (TL) have the highest species count (332 species) followed by Pang Srida (PD), KhaoYai (KY), Dong Yai (DY), and Tapraya (TY), with 293, 271, 169, and 99 species, respectively. We found KY to have the highest recorded carbon storage value at 2507.6 tC/ha followed by TL, PD, TY, and DY (1613.8, 1269.1, 844 and 810.7 tC/ha, respectively). Cluster analysis results indicated that the dominant species in each forest type is different. Moreover, CCA revealed that soil organic matter (SOM) and soil acid-base indicators are the best parameters to establish correlation for each forest type. Based on our results, future climate predictions show a negative impact on evergreen forests, but a positive one on deciduous ones.

Postmodemity of HAN Dong＇s Poetry

With the influence ofpostmodernism, ＂Third Generation＂ poetry rushes out of elite literature and makes Chinese new poetry focus on everyday life of common persons. As one of the most important representatives of ＂Third Generation＂ poets, HAN Dong has created many distinct postmodernist poems. Rejecting metaphor and symbolization, he takes an oral language of original ecology as his poetical discourse mode to affirm the everyday life of here and now, and then both deconstruct metaphoric and symbolic writing of＂Misty Poetry＂ and construct a writing mode of ＂aestheticization of life＂. HAN Dong＇s poetry can be taken as a kind of construction in deconstruction.
