Speculation about Recombination of Vernacular Dwellings in the Contemporary Regional Architecture

Application of local elements in contemporary architectural creation is a process of keeping pace with the times. This paper analyzed several creations of contemporary regional architecture, and discussed the effective approach of achieving the co-existence between tradition and modernity in architectural designs. Against the background of current social cultural development, interpretation of regional architectural culture was reviewed from three perspectives of traditional construction vocabularies, specific regional problems, local cultural artistic ambience. This paper tries to further understand reconstruction of vernacular dwellings, speculate the marginalized regional architectural creation in the fast-developing and explosive construction movements.     

Study on Architectural Concept of Environmental Adaptability of Vernacular Dwellings in Guanzhong-Tianshui Area

Vernacular dwellings are organic products adaptive to local climate and other natural conditions. From the perspective of climatic and geographical features, this study analyzed spatial layouts, outer appearance, courtyard layout and material structure of vernacular dwellings in Guanzhong-Tianshui area, and refined the ecological concepts and technologies adaptive to local environment. Vernacular dwellings are expected to develop sustainably in the evolution of natural environment, and adapt to the development needs of local human settlements.     

Renovation Project of Vernacular Dwellings against the Background of Historical and Cultural Tourism

Taking the renovation project of vernacular dwellings in Chadong Village in Nanlang Town, Zhongshan City for example, historical background of historical and cultural tourism and concrete situation of the project were combined to elaborate the principles, methods and implementation measures of vernacular dwellings in such projects. Renovation projects of vernacular dwellings could protect historical buildings, coordinate regional historical images, and improve the quality of history and culture, so it could be widely applied in historical and cultural tourism of villages and towns.     

Historical Evolution of Vernacular Settlement in Tianshui City

Vernacular settlement is a sum of settlements that keep traditional landscapes in the process of urbanization, and its coverage coincides with that of urban community and rural settlement to some extent. It is a phenomenon of social development against the background of rapid urbanization. As a national famous historic and cultural city, Tianshui City should have had excellent traditional cultural genes as the driving force for its development, however, only fragments of some historic blocks have been left in the recent urbanization. This paper, on the basis of investigating the old urban district of Tianshui City, analyzing the historical phenomenon, summarized the root causes for the status quo of vernacular dwellings in the city, so as to raise the concerns on humanistic thought, and provide proper guidance for the sustainable development of vernacular settlement.     

Evolution and Review of Modern Chinese Vernacular Buildings

This paper divided the evolution of modern Chinese vernacular architecture(1949–2010) into 3 stages: early exploration,confine and confusion,and modern development,by taking time line as the clue,vernacular characteristics of modern architecture in Xi'an during different phases as the support,and combining literature research and field investigation. On this basis,it reviewed historical background,relevant context and typical features of modern vernacular architecture in Xi'an during different phases,and further concluded the evolution laws and research level of modern Chinese vernacular architecture.

Space Image of Traditional Market-Towns in Chengdu Plain from Perspective of Vernacular Culture

Traditional market-towns in Chengdu Plain are blessed with rich vernacular cultural resources. In addition to summarizing characteristics of landscape image, image of downtown street and cultural symbiosis image of the traditional market-town space, this paper, based on the discussion of the renewal design of the Ancient Luodai Town, analyzes the physical elements that constitute the space image, such as the street, interface, area, node and identifiability of landmark building, so as to explore how to create the space image of the traditional market-town with distinctive vernacular cultural characteristics in the construction of the vernacular human settlements.     

Interpretation of the Spatial Form of Chengdu Plain's Traditional Towns from the Vernacular Perspective

In recent years,with the rapid development of urbanization in our country,academic circles have paid more attentions to and made fruitful achievements on the research of vernacular settlement. On this basis,this paper took Chengdu Plain's traditional town spatial morphology as the research object to interpret its spatial form through its composition elements and characteristics which are influenced by nature,history,culture and other factors. And then,it took Jiezi ancient town as an example to analyze the renewal of its spatial form so as to inherit the vernacular culture and promote the conservation of cultural heritage and sustainable development of traditional town in the course of constructing urban cities with Chinese characteristics.

Diversity of seed cesium accumulation in soybean mini-core collections

Radiocesium is an extremely harmful radionuclide because of its long half-life; it is important to reduce its transfer from contaminated soil into crops. Here we surveyed genetic variation for seed cesium (Cs) concentration in soybean mini-core collections representing large genetic diversity. The collections grown over 3 years in rotational paddy fields exhibited varying seed Cs concentrations with significant year-to-year correlations, although the phenotypic stability of Cs concentration was lower than that of the congeners potassium (K) and rubidium (Rb). Although Cs is supposedly accumulated in plants via the K transport system, there was no apparent relationship between Cs and K concentrations, whereas a clear positive correlation was observed between Cs and Rb concentrations. Cs and K concentrations in seed showed slightly positive and negative correlations, respectively, with days to flowering. We selected several high or low Cs accumulator candidates on the basis of the 3 years of seed concentration data. These two groups showed significantly different seed Cs concentrations in another field. The differences could not be explained by flowering time alone. These results suggest that genetic variation for seed Cs concentration is present in soybean germplasm and would be useful for breeding low Cs-accumulating varieties.
