Thorne welcomed the Olympic Delivery Authority's selection of the LDA Design/Hargreaves Associates team to design the park, but warned that the plan must be rooted in British cultural traditions.
LDA and US-based Hargreaves are working together with London-based BBUK, Kinnear Landscape Architects and Sarah Price.
Thorne said: "The British landscape designers whose ideas are driving this project should be acknowledged and congratulated.
"It's good to have pulled in American practitioners too, but landscape is a cultural artefact and the success of the Olympic Park will depend on the skills, imagination and deep knowledge of Britain's parks of British landscape architects Neil Mattinson and Andrew Harland, who led the consortium."
He said the Olympic Park would be a new paradigm for land use and sustainable living.
