Paper Abstract

Chinese government has proposed a strategic development thought named as "Harmonious Society", which contains the requirements to apply Chinese traditional theory to nowadays construction. However, the available theoretical achievement almost all stems from the western, and entirely not suitable for the real situation in China. Meanwhile the research method is fairly traditional. The appearance of the concepts of yin-region, yang-region and yin-yang structure changes the situation of the dominance by a series of westerners' concepts of describing the urban and regional space and theories of spatial structures. Based on the primary achievement of the theory, this article tries to apply GIS methods into the new theory, which makes it more consummate and scientific. This paper will put emphases on discussing the quantitative definition with GIS, evaluate effect and harmonious mechanism about urban yin-yang spatial structure based on existing primary researches of the author's mentor. By means of reasonable division, the yin region and yang region can be defined, and which makes the new definition be quantified and the theory more scientific. First, considering the aspect of economy, social progress and environment, 11 indexes composed of 24 factors are elected as the appraisal foundation. Then, decide the importance of each factor by gifting them different scores(hundred mark system is adopted, that is to say 100 stands for the strongest affection, while 0 stands for having no affection, the score between them from low to high represents the importance variety). Furthermore, rely on AHP (Analytic Hierarchy Process) synthesizing experts' marking methods, the final point is determined. In this way, the scale of the appraisal units scold be fixed. Then we could construct the effect of the factors. By doing this, the factors' entirety affection on every units can be reflected. Accumulating the factors' scores of each unit, the ultimate affection score could be determined by ArcGIS Analysis. Finally, we could divide the units into three groups according to their final score, from high to low they respectively standing for the yin-region, the transition region and the yang region. The research on yin-yang-regions and yin-yang structure will help stimulate the coordinated development of the whole society and make all the people reach an agreement that we should launch positive and effective strategies and measures to improve the development environment of yin-region, promote its transition to yang-region.
