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

Comparisons of advantages and disadvantages among the plans of SWSS renovations provided solid foundation for selecting the most appro-priate plan for engineering projects. In addition,a mathematical model of the optimal combination of renovation plans has been set up and software Lingo was used to solve the model. As a case study,the paper analyzed 15 buildings in Tianjin City. After simulation of the SWSS renovation system,an optimal scheme was obtained,the result of which indicates that 10 out of those 15 buildings need be renovated in priority. The renovation plans selected for each building are the ones ranked higher in the com-prehensive analysis. The analysis revealed that the optimal scheme,compared with two other randomly calculated ones,increased the percentage of service population by 19.6% and 13.6% respectively,which significantly improved social and economical benefits.展开更多
