摘要
应用空间聚类、引力模型改进公式等空间分析方法,从宏观上对长春市城市广场空间结构特征进行研究,并分析其可达性。结果表明:1在数量上,长春市城市广场数量多,分布"北多南少、西密东疏";2在规模上,广场等级呈金字塔型,大型广场分布不均;3在类型上,长春市城市广场以交通广场居多,休闲型广场空间呈现"一核多点"式布局;4在可达性方面,城市中心地区广场可达性较高,城区西北、东北及西南部可达性值较低,中心居民享受广场服务的水平远大于城市周边居民。
The urban square, an important part of a city＇s open space, is the interrelated information hub for people and people and people and cites. It is a necessary facility to reduce city congestion and has been increasingly concerned by citizens and experts. However, the recent studies on urban squares are almost from microcosmic aspect, and the spatial structure of the squares from macroscopic angle has not been studied particularly. Changchun is the sample city in our country on urban squares construction, the development of its urban squares has a history of one hundred years. This paper uses the spatial analysis function of Arc GIS software, such as spatial clustering and the improved gravity model, to analyze the spatial structure characteristics of urban squares in Changchun from a macro perspective. The results show that：（1） In quantity, Changchun has many urban squares contacted with other cities, and the distribution of urban squares is not equispaced, with most in the north and the west of the central city.（2） In scale, there is a pyramid form in the grade of the squares, and the large squares are unevenly distributed.（3） In type, the urban squares in Changchun give priority to traffic function, and leisure squares show the layout of multiple spots with one core.（4） In accessibility, the squares in urban center districts are more accessible, and citizens in the northwest, northeast and southwest of Changchun cannot enjoy so much square service as residents do in the center.
