中文摘要：

首先运用UNA测度长春市中心城区交通网络中心性；然后运用KDE法对交通网络中心性与商业网点进行空间插值，将二者转换为同一空间单位，测算二者相关系数，分析各类商业网点与交通网络中心性的空间相关性及二者关系的统计学特征；最后根据商业网点空间分布与交通网络中心性非协调性提出优化措施。究结果表明：交通网络中心性对商业网点空间分布具有决定性影响；除生产资料市场外，其余商业网点空间分布与交通网络中心性均有较强关联性；邻近度对大型商场和专业店分布影响较大，大型超市和家居建材商店倾向分布于中间性较高的区域，直达性则是影响消费品市场分布较为重要的因素；其中，大型商场、专业店、消费品市场和生产资料市场空间分布与交通网络中心性存在非协调性。

英文摘要：

Street centrality is calibrated in a multiple centrality assessment model（MCA）composed of multiple measures such as closeness, betweenness, and straightness. The paper examines the geography of three street centrality indices and their correlations with various types of commercial networks in ChangChun. The focus is on what type of street centrality （closeness, betweenness, and straightness） is more closely associated with which type of commercial network. And then the KDE method is applied to both street centralities and commercial networks so that the correlations between them can be examined. Results indicate that street centralities are correlated with the spatial distribution of commercial networks in ChangChun, except production material market. Department stores and specializing shops correlate highly with the closeness of street network. The betweenness of street network, however, has a higher impact on the spatial distribution of supermarkets, and building-material shops. Besides, the spatial distribution of consumer markets is more affected by the straightness of street network. There exists non-conformity between the spatial distribution of department stores, specializing shops, building-material shops, consumer markets, production material market, and street network centralities.
