There were quite abundant prototypical ethnic cultures and plant diversity in Qiandongnan ( Southeast of Guizhou) ,where the primitive natural ecology was also perfectly conserved. It was honored by World Native Culture Fund as One of the Eighteen Ecological and Cultural Conservations in the World. The prototypical ethnic culture of Southeast of Guizhou, as a stable life-style and economic culture type of the local people, came into being in the process of the local minorities' communicating, blending and struggling against the natural environment in the long course of history. It could be seen from this research that there were our preliminary research that there are quite abundant resources in Southeast of Guizhou in terms of prototypical ethnic cultures and genetic diversity of glutinous rice. A full reflection of the culture of Glutinous Rice could be seen in the local minority people's daily life, production, custom, religious belief, etc. These showed that the formation and great vitality of the genetic diversity of glutinous rice was not only determined by the diversity of local prototypical ethnic cultures but also to its own biotic condition and its adaptation to natural ecology. It was showed that prototypical ethnic cultures had positive impact on the conservation and utilization of Glutinous Rice diversity. 展开更多

To create a graceful living environment is the core responsibility of landscape designers in the designing process of residential environment. Residential environment design should pay attention to correctly involving cultural feature and environmental and ecological elements which should be integrated in certain living environment through a good design method, so as to reflect landscape designers’ concern on the urban living space. Taking the buildings of Urban Paradise (Paradise in Chinese literature is also called Taohua Yuan, that is, Land of Peach Blossom, originated from the essay by TAO Yuan-ming in the Eastern Jin Dynasty) in Nanning City for example, the research investigated how to integrate ecology and culture in the environment creation of residential district. 展开更多

Traditional Chinese vernacular dwellings take root in farming culture with profound connotations. Through analyzing ecological thoughts and cultural ideas in traditional vernacular dwellings, this study aims to provide references for the design of modern vernacular dwellings. It is proposed in this study that ① Ecological thoughts of traditional vernacular dwellings include the simple eco-thought of 'human-nature oneness', Fengshui (traditional Chinese ideas hold that the location of a house or tomb is supposed to have an influence on the fortune of a family) theories of 'balance of yin and yang', energy-saving thought of 'making the best use of local advantages'. Traditional vernacular dwellings are mainly constructed according to local conditions, facing the sunny side and water, backing on the shady side and mountains, with local materials and suitable construction structures for local environment and climatic conditions, which enable residents to enjoy warm winter and cool summer, sufficient sunshine, excellent ventilation and heat-proof, wind and humidity proof, that is, a natural ecological living environment. ② Cultural thoughts of traditional vernacular dwellings include the strict and square philosophical ideas as well as harmonious artistic thoughts. Traditional Chinese vernacular dwellings demonstrate morals and ethics by strict and square patterns and strong sense of hierarchy, most of them have definite axes in spatial patterns to show the hierarchy and core of construction groups; abstract patterns of flower, grass, animal or human beings are also often applied in detailed designs, showing esthetic tastes. The formation of traditional Chinese vernacular dwellings has been closely linked with social and cultural factors, living habits, geographical, water and soil, environmental and climatic conditions as well as folk customs, which can provide significant references for the design and reformation of modern new-type vernacular dwellings. 展开更多

With the accelerating development of modern residential districts and the improvement of living levels, the requirement of people on environment is increasingly enhanced as well as the demand for culture. Based on people-oriented principle, this design utilized Chinese 'Fu' (blessings) culture to express people’s eager for a better life and the atmosphere of good fortune. It also produced the image of ecological environment by designing water landscapes and plant landscapes, created active space like squares for activity and active water system and developed the characteristics of residential districts by designing landscape sketches and plant landscapes. 展开更多

Buddhism and local cultural traditions have long protected wildlife species and their habitats in Tibetan-dominated areas of western Sichuan. In Daocheng County, the White Eared-pheasant (Crossoptilon crossoptilon) has been afforded special protection by local people because it is conspicuous and white, a color with special symbolism for Buddhists. This and other cultural reasons have led to pheasants and forests benefiting in some areas. Pheasants were found during surveys between January 2003 and June 2004 in forests with varying degrees of local (non-formal) protection. However, there were significant signs that these traditional attitudes were changing in the face of three particular pressures brought to bear by better roads, improving access to and from the rest of China. The first was the development of a significant local demand for the Chinese caterpillar fungus (Cordyceps sinesis), which is much sought after throughout East Asia and mushrooms. Second, and more recent, is a dramatic increase in tourism from major Chinese cities, bringing non-Tibetan values into Daocheng County and changing the local attitudes to all animals. And then, there is a rise in income of the local population, resulting in a higher timber demand for building big houses, which impact all wildlife in the forest, but local attitudes to sacred forests have been retained so far in spite of this increased timber demand. Lessons should be learnt from the impact that unregulated tourism at Chonggu monastery, the most visited area in the county, has on the surrounding forests so that other sacred and non-sacred forests can best be protected for the long term. The alternative is that several Tibetan Plateau Galliformes, currently considered non-threatened because of their extensive distribution in a remote area, cannot be guaranteed such a healthy future. 展开更多

The fusion of urban agriculture, ecotourism and cultural innovation industry has been a necessary way for industry updating, value increase and income im- provement of farmers in suburbs. The methods available of the fusion are as fol- lows: corporation development and operation, led by government with an integrated plan; corporation management and development under guidance of market with sup- port from government; collective development under guidance of market and policies; individual development and operation with the model of "villagers participation de- pending on infrastructure provided by government". The four routes enjoy exclusive advantages and characters. Hence, different villages and towns should adopt the most suitable one according to local conditions for further development and management. 展开更多

Indigenous knowledge and adaptation are the collective information, with improvement from generation to generation. The expectation is that under community control, local expertise on biodiversity will play a significant role in natural resource management through traditional practices. This paper discusses the characteristics and application of the traditional ecological knowledge of aboriginal peoples in northeast India and its role in natural resource management. Examples are provided in two different eco-cultural landscapes, i.e., Demazong (the Buddhist eco-cultural landscape in Sikkim Himalaya) and the Apatani eco-cultural landscape in Arunachal Pradesh, which illustrate the utility value of traditional ecological knowledge in sustainable natural resource management. Both eco-cultural landscapes are indeed very complex and highly evolved systems with high levels of economic and ecological efficiencies. The paper concludes that traditional ecological knowledge systems and institutions could serve as entry points into the sustainable utilization and management of natural resources. This could be achieved through the exploration of the cultural practices of the local people and integrating useful aspects into the modern natural resource management expertise. With rapidly depleting biodiversity in the developing tropic regions, there is a greater utilization today than ever before of the value of respecting the "Sacred" as a tool towards better conservation of natural resources. 展开更多

To expand knowledge on microbial communities of various metal-rich levels of mine drainage environments in Anhui province, China, the archaeal and bacterial diversities were examined using a PCR-based cloning approach. Eight acid mine water samples were collected from five areas in Tongling. Phylogenetic analyses revealed that bacteria mainly fell into ten divisions, which were Betaproteobacteria, Gammaproteobacteria, Alphaproteobacteria, Deinococcus-Thermus, Nitrospira, Firmicutes, Actinobacteria, Deltaproteobacteria, Bacteroidetes, Chloroflexi. Archaea fell into three phylogenetic divisions, Thermoplasma, Ferroplasma and Thermogymnomonas. The unweighted pair group method with arithmetic mean(UPGMA) cluster analysis based on the microbial communities’ compositions revealed that five samples shared similarity with the dominance of Meiothermus and Thermomonas. Two samples had the preponderant existence of Acidithiobacillus and Leptospirillum. The remaining sample owned higher microbial communities’ diversity with the Shannon-Weaver H up to 2.91. Canonical correlation analysis(CCA) suggested that microbial community structures had great association with p H and the concentration of Hg2+, Pb2+, Fe3+, Cl-, SO2- 4in water. 展开更多

This paper studies the impact of handicrafts on the promotion of cultural and economic development for students of art education in higher education through handicrafts based on local customs and traditions. Descriptive, analytical, and experimental methods are used in this research. The results of the study are expected to benefit from the results of this study to provide planners handicrafts in the Ministry of Education. An effective strategy can affect the teaching and learning of handicrafts, the protection of its features and its presence and identity. The study sample consists of 45 students of the third level, batch 2012-2013, from the faculty of Education at the University of Khartoum, Republic of the Sudan. The researchers to prepare topics for handicrafts depend on the use of local materials and units which are derived from the environment and represent the Artistic heritage that is shown through handicrafts (pottery, ceramics, calligraphy, decoration, carpet weaving and textile, sewing, embroidery, sculpture and engraving on wood, metal works, and printing works). The researchers focuse that the students learn the value of handicrafts in terms of economic and method of production and take advantage of it to increase the income of the individual product. The results confLrms the existence of a difference in the quality and value of handicrafts for students in both groups: the experimental and control group, which confirms that the handcrafts lead to the promotion of cultural and economic development for students of art education in higher education. The researchers are recommended to consider of this topic as a main component which enables an area for further studies to develop different strategies in the field of handicrafts, for students to recognize the importance of the handicrafts value in terms of economic and method of production and take advantage of it to increase the income of the individual product. 展开更多

Nitrogen (4, 10, 20 and 40g/m2) and phosphorus (1.2, 4.8 and 9.6g/m2) were applied to tanks to evaluating the effects of N and P additions on plant tissue nutrition and the biomass of two freshwater wetland plants in the Sanjiang Plain of Northeast China, namely Carex lasiocarpa and Carex meyeriana. For C. lasiocarpa, the total N concentration (TN) of plant tissues under the treatment of 10g/m2 was lower compared with the other N treatments. Initially, C. lasiocarpa exhibited a significant increase of biomass as compared with the control value, reaching the maximum of 31.20±4.01g/tank under the treatment of 10g/m2, and then dropped to 18.02±1.53g/tank under the treatment of 40g/m2. For C. meyeriana, TN generally increased with increasing amount of N applied. High N applied produced more aboveground biomass than low N applied. C. meyeriana, as the accompanying species, can adapt itself to the wetland enriched by N, and it may replace C. lasiocarpa as the dominant species of wetland. The total P concentration (TP) in tissues of C. lasiocarpa increased with P addition. The aboveground biomass of C. lasiocarpa increased with P addition, and it changed from 18.77±3.29g/tank to 46.03±3.95g/tank. However, TP of tissue may accelerate the C. meyeriana development under the treatment of 1.2g/m2. P accumulation contributes to the dominance of C. lasiocarpa but limits the production of C. meyeriana, and the latter may disappear gradually from the wetland enriched by P. Increased input of N and P might have an influence on wetland plant community composition and structure, so the effects of nutrient inputs and accumulation should be considered to protect the freshwater wetland. 展开更多

The current study investigates a group of Chinese undergraduates’perceptions of Chinese culture.It examines the discourses that the students drew on to assign meaning to Chinese culture and how the students used these discourses in constructing their Chinese cultural identity.A qualitative study was conducted collecting written self-reflective reports on critical intercultural incidents from 39 Chinese undergraduates at a university in Beijing.Questions designed to evoke reports from the students had them describe incidents in their past intercultural experiences that made them acutely aware of themselves“being Chinese”and specify aspects of Chinese culture that they felt such awareness could be attributed to.A discourse analysis reveals the multiplicity and contextuality of the students’notions of Chinese culture.The findings raise important considerations for contemporary Chinese undergraduates’cultural identity and their much debated“identity crisis.” 展开更多

Comprehensive study on land-use change of spatial pattern and temporal process is the key component in LUCC study nowadays. Based on the theories and methods of Geo-information Tupu (Carto-methodology in Geo-information, CMGI), integration of spatial pattern and temporal processes of land-use change in the Yellow River Delta (YRD) are studied in the paper, which is supported by ERDAS and ARC/INFO software. The main contents include: (1) concept models of Tupu by spatial-temporal integration on land-use change, whose Tupu unit is synthesized by "Spatial·Attribute·Process" features and composed of relatively homogeneous geographical unit and temporal unit; (2) data sources and handling process, where four stages of spatial features in 1956, 1984, 1991, and 1996 are acquired; (3) integration of series of temporal-spatial Tupu, reconstruction series of "Arising" Tupu, spatial-temporal Process Tupu and the spatial temporal Pattern Tupu on land-use change by remap tables; (4) Pattern Tupu analysis on land-use change in YRD during 1956-1996; and (5) spatial difference of the Pattern Tupu analysis by dynamic Tupu units. The various landform units and seven sub-deltas generated by the Yellow River since 1855 are different. The Tupu analysis on land-use in the paper is a promising try on the comprehensive research of "spatial pattern of dynamic process" and "temporal process of spatial pattern" in LUCC research. The Tupu methodology would be a powerful and efficient tool on integrated studies of spatial pattern and temporal process in Geo-science. 展开更多

The objectives of this study were to analyze the biodiversity of the Traditional Gudeuljang Irrigated Rice Terraces in Cheongsando, South Korea's representative GIAHS(Globally Important Agricultural Heritage System) site, with reference to position and land-use features, and to develop a plan to promote agricultural biodiversity in the region. We confirmed approximately 54,000 m2 of Gudeuljang paddy fields by an on-site survey. Of the Traditional Gudeuljang Irrigated Rice Terraces confirmed by onsite inspection, our survey showed that approximately 24,000 m2 are currently being used as paddy fields, approximately 15,000 m2 are being used as dry fields, and approximately 14,000 m2 are fallow. In terms of other non-agricultural land use, there was grassland, including graveyards; artificial arboreal land, such as orchards, rivers and wetlands, and man-made facilities, such as roads and residences. We also confirmed that the Traditional Gudeuljang Irrigated Rice Terraces had higher plant species diversity than conventional terraced rice paddies, and there was a difference in life form characteristics between the two types. Although the superficial topsoil structure is thesame for the Traditional Gudeuljang Irrigated Rice Terraces(TGIRTs) and conventional terraced rice paddies, it is thought that the differences in the subsurface structure of the TGIRTs contribute greatly to species and habitat diversity. However, the TGIRTs in Cheongsando are facing degeneration, due to damage and reduction in agricultural activity. The main cause is the reduction in the number of farming households due to an aging population in Cheongsando. In order to address this problem, we proposed a management plan, related to fallow paddy fields in South Korea, to initiate voluntary activities in the TGIRTs. 展开更多

Seasonal variations in the biochemical composition and the reproductive cycle of pen shell Atrina pectinata in Bohai Sea were investigated from May 2013 to April 2014. Histological analysis indicated that the reproductive cycle of A. pectinata can be divided into two phases, inactive stage and gametogenesis, which were equally and significantly influenced by seawater temperature and food availability. Gametogenesis began in late autumn(October), and completed in June and July. Spawning took place in August, coinciding with the highest water temperature and the richest phytoplankton. The significantly high glycogen content in adductor muscles sustained throughout the late active and ripeness stages, but plummeted during spawning and inactive stages. The protein content in female gonads exhibited a synchronous increase along with oocyte diameter and lipid content, suggesting that the female gonads could accumulate protein and lipid for vitelline in A. pectinata. Furthermore, the RNA/DNA ratio was found to be a useful index to indicate the level of gonad maturation in both males and females. The findings of the present study provided a foundation for the fishery resource administration and the aquaculture development of this species. 展开更多
