| River is the cradle of the ancient civilization of mankind, and the human society is also advanced by fighting against floodwater. In all ages, Water conservancy projects play a vital role in the civilization, while as time goes by, of these projects, some come out, and some vanish. Dujiangyan,with its no-dam irrigation system and a history over2200years of nourishing the plain in the west of sichuan-The land of abundance,has created a irrigational wonder of harmonious coexistence between mankind and nature. It demonstrates its strong vitality and scientificity to people all over the world.By diverting water through The headworks, The Dujiangyan weir and canalsystem was constructed to communicate Ming river and Tuo river. These weir and canal system, like all other rivers in China, are closely associated with the land and cities around. This is so called: The earth of different regions raises different types of people (The unique features of a local environment always give special characteristics to its inhabitants.). Enlightened by this,this essay is to Analyze the relationship between the weir and canal system of Western sichuan plain and the spatial pattern of town and country, more over this relationship becomes extremely unique due to its regionality.To obtain the indissoluble bond between water system and the land of abundant.First of all,we need to investigate and explorate the distinctiveness of the water system itself, understand what is Weir and canal system of Western sichuan plain and its characteristics as the foundation of the following research. Secondly, This essay clarifies influences of the Weir and canal system as well as to the country and city pattern of Western sichuan plain. From the view of Planning major.Thirdly,based on the research of this kind of "phenomenon", the article deepen to the Angle to mechanism what cause the "phenomenon".finally,summarized the interactive mechanism between water, land and city of Western sichuan plain. While with the development of time,the Transportation function of water way is gradually replaced by road.We enter into a time road dominants city transportation therefrom. Modern city construction mostly ignores Weir and canal system’s protection,which causes the damage to Weir and canal system. For the past few years, global raising awareness of ecological environment protection recalls people’s attention to water system.If Road is likened to the framework of development of Western sichuan plain, then Weir and canal system is the blood vessel.Only by making sure the free-flow of the blood vessel,The development of Western sichuan plain can be sustainable in later years.To the series of question, at the end of this essay,we provide a series of strategies of entire protection of Weir and canal system,Basic farmland protection, river reconstruction as well as inner-city channel segment protection.These strategies are just in concert with interactive mechanism of water,land and city. |
