No. Landscape Urbanism is about understanding the city at the scale of the landscape (rather than of the building, neighborhood, metro region, etc) and through the lens of natural systems (rather than artificial systems, sometimes called 'gray infrastructure'). It does not prioritize one type of development over another, it only seeks to find solutions that align the needs of both man and nature to perform better.
Edit: Waldheim's Landscape Urbanism Reader contains a series of essays, some of which are seen as relatively foundational in the field. It's a good place to start.
