Abstract: Along with the acceleration of globalization,regional urbanization and modernization should be quickened and possibility of conflict between urbanization and ecological environment wight be objectively in existence.So we should scientifically understand the character of regional ecosystem,rationally manage regional ecosystem and confirm its direction.In this paper,Qingdao ecosystem was analyzed with some correlative theories of ecosystem management.An ecological safe system of integrality with rational structure and self-contained function was constructed between city and rural area,which was consisted of four sections.The first was the main eco-zone,including the vegetation of forest,grass and the mountain.The second was the controlling keystone zone,including river,lake,and reservoir etc.The third was the ecological corridor in the city,which was made up of green corridor,blue corridor and blue coastline in the city.The fourth was the non-controlling section,which was mainly consisted of huge cropland.Some countermeasures of sustainable use and management for regional ecosystem were put forward:maintaining and strengthening the regional holistic pattern of the mountain and water;protecting and resuming the regional wet ecosystem;pushing industrial ecology with circulation;integrating environmental space with open arms;sustainably using resources; and actualizing biodiversity protection plans for the city.
