北京城市边缘区空间扩展特征及驱动机制

在Landsat TM数据支持下,利用突变点方法获取北京市1994、1999、2004年城市边缘区范围,从扩展总量、扩展类型、扩展方向、扩展区域以及扩展强度等方面分析城市边缘区空间扩展特征,探讨扩展驱动机制。结果表明:(1)北京城市边缘区扩展速率逐渐加快;扩展方向主要是东、北,类型以向外扩张为主;(2)边缘区空间扩展受自然地理条件限制的同时,受经济发展、工业增长、城市基础设施等社会经济因素影响较大,城市规划等政治因素也对边缘区空间扩展具有一定影响。

Urban fringe is a special area with interaction of urban and rural areas.The study of relative research shows that the authoritative theory and methods for demarcating urban fringe have not formed yet,but they are developing gradually from mere qualitative analysis into the combination of the qualitative and the quantitative studies.And maintaining the integrity of administrative units was considered.This article tries to break down barriers of administrative units and gives more precise boundaries by extra...
