The construction of an ecological city must be launched in the dual spatial criteria: in city (urban district) criterion—optimizing the city ecosystem; in city-region (city territory) criterion—optimizing the city-region ecosystem. Luoy-ang has the bright characteristic and the typical image within cities of China, and even in the world. The construction of an ecological city in dual spatial criteria—the city and the city-region—has the vital significance to urbanization advancement and sustainable development in Luoyang. In city-region criterion, the primary mission of Luoyang’s ecological city construction is to create a fine ecological environment platform in its city territory. In city criterion, the basic duty of Luoyang’s ecologic city construction is to enhance the ecological capacity and benefit of the central city.展开更多

文摘The construction of an ecological city has two founda- tional platforms: the small platform, namely urban district or simply called as "city ecosystem"; and the big platform, namely around city district in certain region scope or also referred to as "city-region ecosystem".
