Urban Landscape Reconstruction

Rapid urbanization trends led to unsustainable environmental demand, thus city need a balance development between ecosystem and construction of urbanization for urban sustainability.

While the traditional means of ecological reconstruction can not provide a solution for the human environment and ecological functions. Landscape ecology points out that Ecological reconstruction is a kind of intervention of ecological restoration. Ecological functions can be reinforced and created through the physical structure of the landscape. That means using the flexibility of the ecosystem, take human measures to help the damaged ecological environment gradually restored, or make the ecosystem to the direction of good circulation. Such as restoring the original ecosystem, protecting soil erosion, adjusting the microclimate, purifying the environment, and maintaining the ecological functions of biodiversity. At present, the urban ecological reconstruction mainly relies on the ecosystem self-organization ability and self-regulation ability, artificial adjustment and external intervention as a supplement. The purpose of ecosystem restoration is to continually repair and improve the functioning of the ecosystem, but not to fully restore the ecosystem to its original state.

In general, the terminology "ecological reconstruction" is a description to the solutions for disturbed ecology. Ecological functions can be restored and created through the urban landscape reconstruction, that generally can be sorted into four categories (table 1) including rehabilitation, reclamation, recovery and restoration.
