Along with the process of urbanization accelerating and urban continuous expand and restoration,the city is becoming more and more compact and more urban land is needed to build,so that historical buildings in city are in the embarrassing conditin.Progress of urban modernizition leaded to contracdiction between building of city and protection of original building,ecpecially contracdiction among protection of historical building.These historical building districts have not been satisfied to mordern need,but they are considered as witnesses of history,deliver of culture and memory and decorate of city.Therefore restoration of city will bring about unprecedent opportunities and challenge to historical building districts.Based on urban ecology,theory of sustainable development and the theory of urban programming,I will summarise experience and absorb lesson in the reseach of my paper through current situation and development about protection and use of historical building districts.In the view of urban ecology I observed historical building districts,summarised their characteristics,constitution,fuction and effection.In the end taking the south ground of Chang Chun city as example I analysed and tried finding better method and way to protect historical building districts in the view of urban ecology.The research of my paper in general is summarised as three points:1) Making the use of theory of urban ecology I analysed constitution,specialist,basic function and effection in urban ecosystem.2) The problems of urban ecology of historical building districts and in the process of protection and use of historical building districts.Under the frame of urban ecology I will try to find strategies about protection and use of historical building districts,concluding protecting variety of historical building districts,increasing the ecological status of historical building districts,respecting suppotive scope of historical building districts and resonably expressing top effection of human.
