摘要： 基于1976、1992、2001、2008年的遥感影像,利用“等扇分析法”和基于不等时距的灰色系统方法,分析了延吉市近32年的城市空间扩展过程。在自然、经济、政治、交通等四个主要因素作用下,延吉市城市形态已由团块状转变为星状,城市空间扩展主要沿“布尔哈通河”东西两向、“烟集河”向北三个条带扩展,且这三个条带扩展强度较高;2001~2008年间,城市空间在各方向的扩展差异减小,改变了以往过分集中于少数几个方向的状况。从不等时距的灰色预测结果看,2015、2020年延吉市城市建成区的面积将分别达到106.621和149.516km2,仍将保持快速扩展趋势,且扩展数量较大,而目前延吉市除农业、生态保护用地外,周围可供城市化的土地资源较少,因此建议积极进行规划管理,集约利用土地,实现科学发展,避免城市过分膨胀。

Abstract: In this article,it has been analyzed the characteristics of the expansion trend of the Yanji urban form from 1976-2008, by the methods of "equal fan-analysis" and different time-distance of gray system, mainly based on remote sensing image data in 1976,1992, 2001, 2008.Yanji urban form has changed from mass into a star;the three expansion bands of urban form, expand along the east-west Buerhatong River and the northward Yanji River, the strength of extend of the three bands is highest,by four factors of natural, economic, political, transportation;from the forecast results of different time-distance methods, Yanji urban form will maintain a trend of rapid expansion.But Yanji City has limited available land resources for the urbanization.So it is proposed to take measures early to cope with.

Key words: urban space expansion, measure, estimating, Yanji
