The Study Of Urban Ecological Infrastructure Security

With the urbanization process of our country, our ages become an ages of"big development"and"big breakage", This characteristic and the development mode cause natural landscape system of earth encounter to destroy thoroughly or half-thoroughly, The urban ecosystem is subjected to the serious threat and breakages. Its result not only make the urban ecological security subjected to the threat, The minimum ecological service which the urban and residents needed is hard to satisfy, What's more serious is that it threats the existence and development of human beings'security themselves latently. This study of urban ecological infrastructure is a total of ecological facilities which provides the ecological service for the urban and residents, and a minimum ecological space of the security guarantee of the urban ecosystem, so guaranteeing the security of urban ecological infrastructure also guarantees the minimum ecological space of human beings'existence and developments. on the bass of absorbing the domestic and international related study result, the text applies the theories and methods of ecology, studies urban ecological infrastructure from the security aspect. Because current urban ecological infrastructure research of our country is at the beginning stage, having no perfect theory systems and methods can draw lessons from. on the foundation of defining urban ecological infrastructure and related concepts, The study from three different aspects including region,urban and community to analyze and appraise, trying to divide their security grades, structure their security patterns. Among them, Urban ecological infrastructure security is the minimum space that guarantees the urban ecosystem to develop healthily, is an infrastructure that provides the ecological service for the urban and residents, Region ecological infrastructure is the background and guarantees of the urban ecological infrastructure, while the community ecological infrastructure is the complement and continuing of the urban ecological infrastructure. On the foundation, with the analysis of related cases, the study the urban ecological infrastructure security to the leading function for the region planning,urban planning and the community planning , and provides the ecological support on the mode choice of urban development,the using choice of land and orientation of the urban spaces to extend. The text expects to study the urban ecological infrastructure security, promote and perfect the planning and construction of urban ecological infrastructure, guarantee the urban ecological security, guide the urban planning and developing, provide the support of theory foundation for realizing the sustainable development of the ecological urban.
