摘　　要：宁波城市边缘带形成因为地跨市县两级行政地域等因素而具有地方性特征本文在ＧＩＳ技术的机助支持下，利用ＤＴＭ信噪度分析，对宁波城市边缘带空间范围进行界定，进而探讨边缘带景观特点、地域扩展趋向等诸多问题．Based on land-use maps and rectified aerial photographs taken from 1990 to 1996 with scale of 1:10 000 and 1:50 000, a data terrain model (DTM) and associate application cartographic models of Ningbo urban-fringe are built up. Some technical aspects of this process are firstly discusse. The spatial scope and boundary of Ningbo urban fringe by using a series of computer-assisted mapping and spatial analysis operations,such as overlying, cartography reclassification etc are outlined. The landscape features, spatial extension tendency of Ningbo urban fringe are summarized.
