摘要

城市蔓延是一个全球性的问题,然而,发展中国家未能有效地克服这一问题。例如,在巴基斯坦,城市发展政策是脆弱的,城市地区仍然没有明确的边界。这一失败主要导致了该国主要城市的不受约束的扩张。一个令人担忧的事实是,大多数城市扩张一直发生在城市边缘肥沃的农业用地上。研究人员通过文献和卫星图像的监督分类验证了这个问题,具体验证了白沙瓦市的增长。这项研究有助于揭示巴基斯坦无限制城市扩张的根本原因及其后果。最后提出了抑制城市跨越式低密度无序增长的改革措施和技术措施。

Drivers of Unfettered Urban Sprawl in Pakistan
Urban sprawl is a global concern, however, developing countries are failing to effectively overcome this problem. For instance, in Pakistan, urban development policies are tenuous and urban areas remained without certified boundaries. This failure is mainly causing an unfettered sprawl in major cities of the country. An alarming fact is that most of the urban sprawl is consistently taking place on fertile agricultural land in the peripheries of cities. The researcher has verified the problem through literature and by supervised classification of the satellite imageries to specifically verify growth of Peshawar city. This research contributed to unveil the fundamental causes of the unrestricted urban sprawl and its aftereffects in the context of Pakistan. Finally certain reforms and techniques are suggested to curb leapfrogged and low-density haphazard growth of cities.
