Research And Landscape Design Of Eco-industrial Park In Tianjin Lingang Based On Circular Economy Theory

The coastal saline-alkaline land in Tianjin is one of the representatives of the coastal saline-alkaline land in China.Because of the special climate and the hydrological geology of Tianjin,the ecological environment is fragile,and the development of the land has been stressed and restricted.Under the guidance of the concept of circular economy,this paper analyzes and summarizes the main models and typical cases of agricultural and forestry circular economy at home and abroad.Then,taking the eco-industrial park as the breakthrough point,the comprehensive utilization of ecology and economy of saline-alkaline land was realized through the construction of the agroforestry model and the design of ecological cycle mode.At the same time,combined with landscape design,to create a view of local landscape.By setting up some kinds of leisure and entertainment projects to attract tourists to visit.In this paper,the strategies and methods of landscape construction of eco-industrial park were put forward according to the conditions of saline-alkali soil.The conclusion of the paper can not only provide a theoretical reference for the sustainable development and utilization of saline alkali soil,but also provide a reference for the landscape construction of eco-industrial park in the future.
