The Inspiration Of Sponge City Based On The Planning And Construction Of Urban Landscaping In Qingdao During The German Occupied Period

Problems of urban hydrological environment have gradually highlighted in the new era of Chinese urban development.For example,life,ecology and property have been greatly threatened.So the "sponge city" was put forward and highly anticipated under such background.The construction of the sponge city aims to keep the hydrological characteristics unchanged before and after urban development and to solve social focus issues from the source,such as urban rainwater,urban water resources,urban hydrological and so on.Qingdao is currently affected by droughts and floods.Therefore,how to economically and efficiently construct sponge cities will be an inevitable choice.The construction of Qingdao's sponge city has a very good historical foundation,it has a urban garden green space system which is more mature.The development of Qingdao's garden green space began during the German occupation at the end of the 19 th century and has been developed for more than 100 years.Especially in the early Qingdao,the German colonists rationally lay out garden green spaces and solved the issues of urban hydrological environment,such as soil erosion and scarce vegetation,through the way of planting trees.Because of the obvious regional characteristics of Qingdao's garden green space system which was created during the German occupation.And the construction of Qingdao sponge city is also to improve the urban hydrological environment.Therefore,the thesis provides a reference for the current sponge city construction through exploration of the planning layout and related technologies of the garden green space during the German occupation.The main contents about the development of garden system of Qingdao's Old Town in the thesis are as follows.In the first chapter,the thesis explains the background,purpose,significance,content and framework,besides it introduces the research methods.Finally,the research status at home and abroad are introduced.In the second chapter,the construction foundation and development of garden green space in Qingdao during the German occupation were studied,and the development process of garden green space was systematically sorted out.In the third chapter,it researchs the layout of garden green space during the German occupation from planning layout,natural factor influence and avenue based on the perspective of sponge city.The fourth chapter mainly studies the construction technology of garden green space during the German occupation which is based on the perspective of sponge city from three aspects,such as tree species selection,natural environment improvement and policy management.Finally the fifth chapter summarizes the enlightenment of Qingdao sponge city construction.
