摘　　要：运用城市流强度模型和交通等时圈划定方法,分别对延边朝鲜族自治州各城市的外向功能量和城市经济区范围进行了定量分析与空间可视化表达.结果表明:延边朝鲜族自治州自西向东包括敦化经济区、延吉经济区和珲春经济区;区间引力差别较大,其中延吉经济区引力最强;区间互补性相对较弱,在发挥地区优势的同时应加大经济联系,加快协调发展.By using urban flow intensity model and traffic circle demarcating method, making quantitative analysis for the cities＇ outward function, and spatial visualization for city economic zone of Yanbian. The results show that：from west to east, the state of Yanbian including Dunhua economic zone,Yanji economic zone and the Hunchun economic zone; interval gravity varies greatly, and the strongest gravitational is Yanji economic zone;interval complementary is relatively weak, playing area advantage should have the equal level with strengthening economic ties, to accelerate the coordinated development.
