Abstract
We have acquired a new concept by applying the ecological systems to cities, and named it “urban ecology”. Then we have established a new planning method to realize cities that will contribute to the global enviroment. This planning method is known as “ecological urban design”.
We have developed an evaluation system for city's environment to evaluate the planning properly. This system enable us to quantitatively and quickly evaluate plans during the initial planning stages. This prosess is conducted based on the following three criteria: a city's “self-sufficiency”, “livability” and “sustainability”. So that the planning can contribute to the global environment, this system makes it possible to improve the plan highly.
