Abstract: | The urban fringe, which can be seen as a special form of regional ecosystem with a spatial transition from urban to rural
areas, has strong heterogeneity and is a typical ecologically sensitive area. The expansion of cities and the landscape effect
of the changes have attracted wide attention. The primary aim of this study is to obtain an understanding of the spatial patterns
of landscape conversion and the corresponding environmental sustainability. With the help of GIS and Fragstats software, the
changes of landscape patterns before and after town planning were compared in An-Ding town of Beijing, of which the sustainability
was also revealed based on the ecological footprint using social and economic statistic data. The results showed that the
landscape pattern changed greatly during its conversion from several villages to a small town and the landscape fragmentation
increased due to road construction. Meanwhile, human disturbance increased with the constructed land extension. For the gap
between the ecological footprint and the biological capacity, An-Ding town ran an ecological deficit at that period, which
means it was unsustainable. However, the environmental sustainability decreased after planning due to the degraded green land
and forest. The results suggested that ecological management should be strengthened during the town planning period. |
