Green space planning and land use: An assessment of urban regional and green structure planning in Greater Copenhagen Ole H. Caspersen, Cecil C. Konijnendijk & Anton S.

In this paper, the development of the urban green structure in Keywords Greater Copenhagen is elaborated upon, focusing on land use Green structure, land cover, landscape change, recreational areas, changes and the effectiveness of regionally coordinated planning regional planning measures.
