It is evident that several cities in China have experienced a variety of global impacts. Beijing for instance, has become synonymous with mass-migration over the years. The immense scale of projected rural migration, the unmanageable intervention of new housing urban developments, and the high levels of air pollution in Beijing have become a global dilemma. In order to alleviate Beijing’s critical ecological conditions, the introduction of “new lungs”, as an urban environmental design to the city should be examined. This thesis project illustrates how urban productive landscape and bike infrastructure can be essential in urban development through the implementation of an innovative dynamic Urban Eco-Filter that would respond to the active circumstances of the city of Beijing. The enormous amount of air pollution, ground-water depletion/pollution and particularly the lack of an ecological footprint are some of the challenges the city of Beijing continually battles. As a potential solution to assist the citizens of Beijing, who continually struggle to maintain a better quality of life, this thesis project proposes a new Urban Eco-Filter approach that will serve as a green corridor incorporating environmental resources. This innovative urban infrastructure would become the exceptional and unquestionable tool to create a holistic environment including productive urban landscape, bike infrastructure and sustainable themes.As a solution this project proposes the implementation of an elevated eco-network infrastructure in the center of the city of Beijing. In addition, the proposal would focus on developing a new productive landscape connection prototype at the Guomao Bridge on the 3rd Ring Road. The procedures analyzed are: case observation, case studies, strategies of 3-D modeling, and the design and qualitative investigation through workshops. In order to further validate the proposed solution, an in depth evaluation of the research techniques is necessary.It is indispensable to analyze the existing hazardous urban conditions and consider the uncontrollable growth of metropolitan cities, while introducing new ecological bike infrastructure. With the limited environmental footprint, constant amount of air pollution and the deficiency of ground-water, the investigation of a new Urban Eco-Filter is encouraged to enhance the social and environmental fabric of the city of Beijing.The proposal is a speculative urban design proposal for Beijing that attempts to remediate the process of urbanization and transformation with a landscape infrastructure at one scale which also becomes a connector to the landscape/ecological infrastructure at the metropolitan scale, and a connective tissue for disparate green networks and systems.It is apparent that Beijing is suffering from excessive urban expansion. If the current trend continues, Beijing may be collapsing to a complicated future. The development of the city is moving away from the monocentric model established by the Tang Dynasty (618-907). From 1953 to 1993 five master plans were submitted for review in order to avoid urban sprawl; however, these schemes have not been able to control the mass-migration to the city. This problem has contributed to air contamination, lack of green urban spaces, decrease of ground-water, and the insufficient supply of natural food products.Until recently, China was known as one of the most self-sufficient countries in the world. Presently, China is importing natural food products from other countries in order to survive. During the Asiatic Society of Japan in 2001, Professor Makoto Taniguchi stated that, “By 2020, China could be the biggest importer of food after Japan”. New urban developments seem to focus more on the car and not the pedestrians, this is another worry Beijing is dealing with. Likewise, the depletion of ground-water should be taking into consideration because it is rapidly disappearing. Consequently, it has been prognosticated that Beijing in approximately twenty years would no longer be the capital of China. All these concerns could have solutions if new design ideas were implemented. For this reason, this thesis exploration will analyze the possibility of introducing “new lungs” to Beijing in order to improve the dynamic conditions the city has been facing.This intervention will deliberate a sequence of outcomes to improve the lifestyle of the residents of the city of Beijing.
