The two principles for selecting the site of the eco-city: one is to embody the exemplary significance of establishing an eco-city with resource constraints, especially in an area dominated by non-arable land and lack of water resource; the other is to be in proximity to a centric city, with the support of mega-city's advantages in transportation and service, to save construction cost of infrastructure.
