以1991年、2000年、2010年3个时相LandsatTM／ETM。影像为数据源，采用监督分类提取了研究区建设用地信息，从规模和强度、方向、梯度与格局等5方面分析了浙北山地平原过渡区建设用地扩展的特征。研究表明：1991--2010年建地设用规模大幅度增加，扩展强度总体呈上升趋势，市中心的上城区和下城区变缓，拱墅区较为稳定，而其他县（区）上升趋势较为明显。建设用地扩展具有明显的方向性，东面各个方向的扩展强度明显高于西面各个方向的扩展强度。建设用地扩展格局存在高（低）值集聚现象，且中心极化和集聚现象在不断增强，空间扩展热点区整体上表现出由“一核五星”演变成“两核三星多点”的建设用地扩展格局。

With the Landsat TM/ETM＋ images of 1991, 2000 and 2010 as data source, this paper analyzes the expansion characteristics of the construction land in the transition zone in between mountains and the plain of Northern Zhejiang Province in terms of scale, intensity, direction, gradient and pattern based on the information of construction land area in the transition zone collected by means of supervised classification. The study indicates that the scale of construction land increased dramatically from 1991 to 2010, the expansion intensity being continuously rising, and that in the downtown areas, the expansion intensity slowed down in Shangcheng District and Xiacheng District and it remained relatively stable in Gongshu District, while the expansion intensity of other counties （districts） increased obviously. The expansion of the construction land assumed obvious directionality, with the expanding intensity of the eastern direction much higher than that of the western direction. The expansion of construction land had a pattern of spatial agglomeration, with the polarization and agglomeration around centers and sub centers continually increasing, resulting in the expansion pattern of construction land turning from ＂one core and five stars＂ to two cores and three stars plus many points
