紧凑理念下的米脂城市空间增长边界划定

摘要

城市空间增长边界的划定对于土地资源的集约利用和城市的可持续发展至关重要.文章以紧凑理念为引导,借助ArcGIS平台,通过边界基准模拟、边界比较择优和现实发展校验三个步骤进行空间增长边界的划定,并以米脂城市空间增长边界划定为例进行实证分析,得出划定的空间增长边界将有助于指导米脂城市的空间建设和可持续发展.%Delimitation of UGB (urban growth boundary) is crucial for compact land use and sustainable urban development.With compact urban development concept,the paper introduces the method of UGB delimitation through basic simulation,comparison and choice,and practical verification with ArcGIS platform.The method is practiced in UGB delimitation of Mizhi city.
