Study On The Urban Design Fornew Town Areas Of Mountainous Small Towns Based On Compact City

After having started to take shape initially, mountainous small towns will get to thestage of rapidly accumulating urban development resources such as population andindustry, and town expansion will be needed to lighten the population burden. However,during the process of urban space expansion, mountainous small towns may encounterthe phenomenon of urban sprawl, causing serious waste of land resource andenvironmental damage, inflicting irretrievable losses on mountainous small townswhich usually face inadequate land resources and vulnerable ecological environment.Therefore, the new town expansion of mountainous small towns should be based onconstructing resource-saving towns, trying to make use of urban development resourcesin a efficient and sustainable way so as to achieve intensive urban expansion instead ofurban sprawl.The theory of “Compact City” advocates an intensive use of urban resources,pointing out the direction for the new town expansion of mountainous small towns. Theprocess of urban design requires integrating multiple domains and emphasizing themeaning of dimensional thinking for three-dimensional urban space research, providingdetailed approaches to designing urban space during new town expansion. So, the urbandesign based on “Compact City” is significant for mountainous small towns in toexpand in an intensive way. However, as an urban development principle instead of adetailed urban form,“Compact City” has different spatial performances in differentregions or in different stages of urban development, which means when based on“Compact City”, urban design for mountainous small towns will not be completelythe same as urban design for mountainous large cities, they share some commonfeatures but are different from each other in many ways at the same time. Based on thisfact, the dissertation focuses on the new town expansion of mountainous small towns asthe object of study, discussing how “Compact City” should be adopted to guide theurban design for mountainous small towns in an adaptive way, so that “Compact City”can be more pertinent when it is practiced in urban design for mountainous small towns,and avoid imitating the urban design for mountainous large cities without consideration.This dissertation is mainly divided into three parts:Part one includes the first and the second chapters. By analyzing the relevantresearch areas including “Compact City”, small towns and mountainous towns, this part clarifies the significance, the objective range, the methods and frame of thisresearch topic. Then, taking the cases of Sichuan and Chongqing areas as an example,the dissertation analyzes the strengths, weaknesses, opportunities and threats of the newtown expansion of mountainous small towns, and concludes the key problem of the newtown expansion of mountainous small towns, providing bases for introducing“Compact City” and urban design in part two.Part two includes the third chapter. By analyzing the connotation of “CompactCity” and urban design, this part demonstrates that urban design based on “CompactCity” possesses important significance for the new town expansion of mountainoussmall towns, and also points out that it has certain differences from urban design formountainous large cities, and raises four performance characters of “Compact City”in the urban design for mountainous small towns.Part three includes the fourth, the fifth，the sixth and the seventh chapters. This partexplains and analyzes in detail the four characters of urban design for the new townexpansion of mountainous small towns based on “Compact City”, and thenintroduces a relevant practice project to further support the research, and summarizesthe whole research at the end of the dissertation.
