Abstract
Defines urbanisation as those areas with a population of >620 individuals km-2. Characteristic urban structure and the range of components are also described. Urbanisation is seen as presenting a complex environmental gradient. Landscape ecology is discussed. By studying urban gradients humans can be seen as integral and critical components of ecological systems. -S.J.Yates
