Abstract：The construction of ecological city is a objective need for the humanity to protect the living environment. It is an inevitable result of the economy, society, modern science and technology development. Meanwhile, it is an inescapable choice of realizing the global sustainable development. There are two basic platforms for the construction of ecological city, one is the urban district, namely "city ecosystem".The other is the district around the city, namely "city-region ecosystem". The "city ecosystem" is a complex humanity eclogical system keeping close contact with a certain region, which takes the city crowd as its main bodu while others such as secondary physical feature, natural resources, artifical material factors, are taken as its environment. It's the essence and the primary part of ecological city. But ecological city periphery, the district around city in a certain region, namely the "city-region ecosystem", is the region supporting the ecological city. In light of the deduction, the construction of ecological city must be launched with the dual space dimension: city dimension and city-region dimension in which the city ecosystem and city-region ecosystem can be optimized respectively.
With important geographical location, complex natural condition and rich natural resources,Luoyang city is featured with unique economic structure and diverse human elements. It's of the great significance for Luoyang city to construct city eco-system with the dual space dimension. It will help Luoyang advance its process of urbanization and sustainable development. In its city-region dimnesion, the primary mission is to create an environmental platform with good ecological system. The measures should be taken as follows:
(1) to protects the resource of the primary productive force, and improve its productivity;
(2) to develop the ecological economy and enhance the industry technology content;
(3) to raise the level of regional urbanization and impetu healthy development of urbanization advancement;
(4) to conformitie resource superiority and advance ecological tourism.
In the city dimnesion, the basic duty of the ecology city construction in Luoyang is to enhance the ecological capacity and benefit of the central city. Its main measures are:(1) to expand new space of the city district and extend the city ecology capacity;(2) to optimize the open space and organize the space pattern of the ecology city; (3) to manage the ecological city by market idea and enhance the resource disposition benefit;(4) to strengthen the environmental protection and govern environmental pollution.
