We describe the green space system planning and design of a new Kaixian City for migrants in the Three Gorges Reservoir area of P.R.China. The goal of the project was to provide a high quality settlement for migrants relocated from the old Kaixian City that had a history of over one thousand years and from other places with different traditional cultures. Our efforts focused on conceiving affordable strategies to increase green areas, improve waterfront landscapes, deal with water level fluctuation,integrate diverse folk cultures, and encourage bicycling as an environmentally-friendly form of urban transportation.The new city is anticipated to benefit from the green space systems with an improved eco-environment, enriched tourism resources, cheap landscaping costs, relief from traffic pressure, and in other ways. The planning philosophies employed could be useful in the engineering and construction of other cities in the Three Gorges Reservoir area.
