Study On Landscape River Regulation Of Urban Inland River In Mountain Area

With the rapid development of national economy and the heightened awareness of environmental and ecological protection,more and more attentions are put into the protection and sustainable development of mountainous urban rivers.Thus,the mountainous urban rivers become important and indispensable elements of mountainous urban ecological development.There is a long time since the study of urban inland landscape river at home and abroad,especially in our country,in the condition of large scale expansion of urbanization,in order to plan land-use and improve the flood control function of rivers,the most urban rivers have been canalized and hardened,losing their ecological features,which greatly destroyed the ecosystem balance of rivers.In reaction to the phenomenon,through elaborating critical technologies,design philosophies and other aspects of the renovation of landscape watercourse process of Yuxi river,Lushan county,this paper carried out practical research relevant to the renovation of landscape watercourse of mountainous urban rivers.This paper systematically neatened relevant theories of renovation of landscape watercourse of mountainous urban rivers and analyzed the related concepts,targets,principles and so forth,putting the testing course of Yuxi river as the research object and trying to build a harmonious relationship between human and water and people-oriented river ecosystem.Additionally,the paper studied key technologies and practical applications of the design of channel planforms and vertical forms.Combining the comparison results of dikes and analyses of landscape staunches,the basic ideology and strategy of waterfront landscape design are discussed.To be specific,through landscape characteristics of riverside forest,green belts of embankment,riverside wetland and natural tidal flats formed by main landscapes,roads,green belts,gallery roads,lights and public facilities,the ecological quality of landscape rivers can be improved and the quality and image of mountainous city can be enhanced,the ecological functions,flood control and leisure services can be activated.Finally,through evaluating and analyzing environmental benefits,ecological benefits and social benefits of later period,this paper pursues appropriate strategies and development directions of renovation watercourse in mountainous cities,hoping for providing certain references for future renovation of watercourses to landscape rivers in mountain cities.
