the habitat of urban vegetation was specialization.Under the human planning and management

urban vegetation is turned into the land with parks and woods day after day. The succession of urban vegetation is a plagio-succession or retrogressive succession

so urban vegetation is a plagioclimax or disclimax. The function of urban vegetation is multiple

but the main efficiency is changing and regulating the urban environment for improving the human living and working condition.But to develop the function of urban vegetation

the conservation and maintance by human are necessary.The study about floristic

structure

type

ecology

dynamic

function etc. of urban vegetation and the relationship with the urban environment is termed urban vegetology or urban phytocoenology. It is a branch science of vegetology or phytocoenology

a new science. Like that “urban biology”

“urban zoology”etc. also is a new science separately. Those will contribute to the urban construction and urban sustainable development.
