自1986年开始实施“Doi Moi”政策以来，河内的城市地区发生了重大变化。利用陆地卫星和先进星载热发射和反射辐射计（ASTER）场景对河内市建成区进行了识别，并利用空间指标对1975年至2003年的城市变化格局进行了表征。首先，采用“相似邻接百分比”空间度量来识别城市增长模式，将城市增长模式划分为3个子模式：扩张增长、填充增长和外围增长。其次，使用空间度量分析程序（FRAGSTATS）调查了1975-1984年、1984-1992年、1992-2001年和2001-2003年期间城市城市化的驱动力。20世纪80年代后期沿着主要交通路线扩展城市区域被确定为河内城市化的主要形式。本文展示了空间度量作为辅助信息来源的潜在应用，以支持遥感数据及其用于表征城市增长模式。
Since the beginning of the ‘Doi Moi’ policy in 1986, Hanoi has witnessed significant changes in its urban areas. Landsat and Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) scenes were used to identify built-up areas in Hanoi, and spatial metrics were used to characterize urban change patterns from 1975 to 2003. Firstly, a spatial metric called the ‘percentage of like adjacency’ was used to discern urban growth patterns, which were classified into three sub-patterns: expansion growth, infill growth and outlying growth. Secondly, the driving force underlying the urbanization of the city for the 1975–1984, 1984–1992, 1992–2001, 2001–2003 periods was investigated using a spatial metric analysis programme (FRAGSTATS). The expansion of urban areas along major transportation routes in the latter 1980s was identified as the main form of urbanization in Hanoi. This paper shows the potential application of spatial metrics as secondary sources of information for supporting remotely sensed data and their use to characterize urban growth patterns.
