摘　　要：This paper takes metropolitan area of Chongqing Municipality as an example, Chongqing, located at the tail area of the Three Gorges Reservoir; is a typically in-land hilly city in China. A series of serious eco-environmental hazard affecting hilly city, have appeared： the forest landscape has been fragmented; the stability of ecological system has nat been maintained： soil erosion has been serionus; geological disasters have become more and more frequented; the phenomenon of city ＂heat islands＂ is obvious： and environmental pollution is worsened with Iow physical self-puri- fication. All of the hazards above will affect ecological security of the tail area of the Three Gorges Reservoir and sustainable development of Changqing. In order to guarantee ecological security and health of Chongqing and the Three Gorges Reservoir, the eountermeasures for ecological infrastructure construction are put forward： quickly drawing up ecological infrastructure planning of Chongqing Municipality, strengthening the integration and continuation of hilly-water spatial pattern, maintaining the diversity and stability of local ecosystem, establishing the green space system in-cluding suburban.forest, farmland and green space. recovering wetland ecosystem, optimizing industrial structure and urban spatial distribution, developing recycling economy; establishing ecological infrastructure monitoring network and information forecast system, carrying out ecological management for Chongqing Municipality and so on.This paper takes metropolitan area of Chongqing Municipality as an example. Chongqing, located at the tail area of the Three Gorges Reservoir, is a typically in-land hilly city in China. A series of serious eco-environmental hazard affecting hilly city have appeared: the forest landscape has been fragmented; the stability of ecological system has not been maintained; soil erosion has been serious; geological disasters have become more and more frequented; the phenomenon of city "heat islands" is obvious; and environmental pollution is worsened with low physical self-puri-f ication. All of the hazards above will affect ecological security of the tail area of the Three Gorges Reservoir and sus-tainable development of Chongqing. In order to guarantee ecological security and health of Chongqing and the Three Gorges Reservoir, the countermeasures for ecological infrastructure construction are put forward: quickly drawing up ecological infrastructure planning of Chongqing Municipality, strengthening the integration and continuation of hilly-water spatial pattern, maintaining the diversity and stability of local ecosystem, establishing the green space system in-cluding suburban forest, farmland and green space, recovering wetland ecosystem, optimizing industrial structure and urban spatial distribution, developing recycling economy, establishing ecological infrastructure monitoring network and information forecast system, carrying out ecological management for Chongqing Municipality and so on.
