The Research Of The Relationship Between Urban Space Morphology And River Migration Of Tianjin From Ecological View

Tianjin,a city has more than 600 years' history,is the economic center in the northern region since the beginning of the 20 th century,as the development of maritime and river transportation.In recent decades,the situation of ecological problem in river system became the bottleneck,restricting the ecological city development.City image,economic benefit and living quality in Tianjin are all effected by ecological environment and development strategy in riverside area.Therefore,protecting riverside ecological environment is an essential part of urban planning and construction.In Tianjin,river migration as a natural environment cue,tends to be linked with the urban spatial morphology changes.Understand the roles between them,could impact on Tianjin urban spatial morphology development in a positive way.The object of this study is the interaction of river migration and urban spatial morphology transformation.Literature review,chart analysis and multidisciplinary approach are the main methods in this study,to fully express the connection between migration of channel and transformation of urban spatial morphology.Thus,a correct urban development direction conclusion can be drew.Firstly,the study will start by dynamically organizing the theories and studies on urban spatial forms and river channel migrations,to find any link between these two ecological characteristics so that the interaction between them can be determined.Then take Tianjin city as the study object,discussing the effects between river channel migrations and urban spatial forms respectively,based on the compare of data changes among in previous data resources,such as maps,rive morphology,hydrology and ecological conditions.Finally,based on analyzing the present situation of ecological elements for the river,this report will give suggestions for Tianjin city's space optimization so that the disadvantages can be altered.This report has analyzed the interactions between the gradual process of Tianjin city's space spatial form and the river channel migration;suggestions have been provided to optimize the city space according to river ecology.This report has significance on preventing conflictions between city development and river ecology which caused by blind constructional activities.Moreover,the report is also critical for achieving sustainable development in urban area.
