查询词典 spatial change

The ethnic place was formed through the spatial dynamics of "territorialization" which includes cross-bordering and border-making of different scales. Firstly there were the transnational flows of Vietnamese contract workers, marriage immigrants, and oversea Chinese that transplanted on the Taiwanese society. At the regional level, the interstice resulted from the decline of traditional retailing market, unfavorable location, rent gap, and the stigma of low-income housing was confronted by the change of population composition and life style induced by middle-class housing development, leading towards exclusion and remaking of borders that ended the interstice, and it is a middle class "territorialization" driven by the appeal of safety and "de-stigmatization".

族裔化地方在「疆域化」的空间动态中形成，涉及不同尺度的跨界和划界行动：越南移工和婚姻移民的跨国流动，以及早期越南华侨的跨界流移和在地著根；地区尺度上，传统零售市场的萧条、区位条件和地租差、平价住宅区污名形象共同构成的「缝隙」，面对中产阶级房地产开发导致人口结构和生活形态改变，引致了排斥和重新划界的压力：一场以「去污名」和消除恐惧地景为诉求的阶级疆域化，终究消灭了这个「缝隙」。

The innovations of this paper as follows:(1)The topological relation model between complex spatial objects is brought forward, which represented by some composite basic 9I matrix and results in general signification.(2)Time and space integrated topological model is suggested to reason about spatio-temporal change types;(3)Sweep-line algorithm is improved, and a new little circles of polyline nodes overlapped with region method is proposed. As result, it's efficient to calculate line-line, line-region and region-region topological relations.
