The research of ecological pattern construction based on ecological infrastructure valuation

Opportunities and strategies for sustainable development have been significantly challenged by global climate change, the recent economic recession and the rapid urbanization. One of the most critical issues for China and the World continues to be demand for limited resources and the determination on how to create a sustainable approach of planning and management. With the emergence of the concept of ecological infrastructure (EI) in 1980s, greater attention has been given to an integrated and systematic solution to regional and urban ecological and environmental problems. In view of the policies energy saving and emission reduction and environmental impact assessment and the vision of building of low-carbon city and eco-city, the strategy of ecological infrastructure has been played an important approach to the ecological pattern construction. This paper proposes a four-step ecological pattern construction approach to develop synthetic solutions to the regional ecological and environmental problems based on theory of ecological infrastructure. Taking the Jiujiang city of Jiangxi province as an example, the study demonstrates how to use ecological infrastructure as a method to guide and frame ecological pattern construction.
