The Design Of Landscape Green Rainwater Transfer Infrastructure

In recent years, water logging frequently happens in urban area in China, which becomes a serious threat for the residents. To improve the Rainwater ecological environment and achieve the Urban Sustainable Development, we begin to construct a large amount of Green Rainwater Transfer Infrastructure. As an important solution and method to transfer the rainwater, it can effectively collect, transfer, reserve/infiltrate and purify the rainwater.This thesis classifies the Landscape Sustainable Rainwater Transfer Infrastructure from both the external form and the internal landscape based on the study of numerous local and international rainwater transfer infrastructure projects. Besides that, this article also concludes four functional characteristics- the combination of transportation and reservation, the purification and infiltration, the control of rainwater emissions and the transformation from green Rainwater into grey Rainwater. Five characteristics of Space layout are also presented- the set-up of green space, the non-point source proximity, the linear continuous form,the imitation of nature and the multiple scales usage capability. Moreover, the landscape composition of transfer infrastructure system assists people to understand the characteristics of the landscape design of Green Rainwater Transfer Infrastructure. At the end, the Harmonious garden district in Tang he is chosen as the actual project to process the Rainwater drainage system renovation. The Green Rainwater Transfer Infrastructure in four areas which includes the parking lot, building entrance, sales department, and the main roadway would contains the detail landscaped design.
