Local vernacular dwellings can be classified in the following 3 ways on the basis of their own regional features:First, classifying by the origin and development history:stilt building, courtyard and non-courtyard building, western-style building; Second, by building materials:bamboo-wood building, stone building, adobe building, earth-stone building, brick-wood building, building of mixed materials; Third, by architectural form:stilt building, courtyard building, non-courtyard building. Stilt wooden building in northern Guangxi is a representative of traditional vernacular dwellings in the study area. By giving mature consideration to inheritance and development of cultures of traditional vernacular dwellings, this study proposes that proper renovation plans should be made according to actual conditions of the planning site; form renovation of vernacular dwellings should be taken as the new trend of renovation; traditional cultures should be further explored, demonstrated and protected. These suggestions are of great instructive significance for improving the cultural taste of townscapes.展开更多

Significance of protecting and developing natural environment in the present town planning was discussed. Overall planning of Queshan County of Henan Province (China) and planning of new district in Paris (France) were taken for examples to analyze natural environment protection and development pattern of towns in terms of the overall town planning and overall form control. Meanwhile, the destruction of public welfare eco-forest caused by too many water conservancy projects in Zixi County of Jiangxi Province (China) was analyzed to propose a natural environment protection and development pattern from the perspective of ecological engineering construction. Finally, it was stressed that natural environment should be respected in the planning, human-nature harmony integrated into the planning concepts, conflicts between town construction, protection and renovation of natural environment resources coordinated, and instructive measures adopted to settle problems in town planning.展开更多
