Research On Urban Secondary River Landscape Design Based On Naturalization Concept-- Taking The Zhuxi River Project In Chongqing As An Example

With the rapid expansion of urban scale,many secondary rivers gradually become rivers within the city from the original natural rivers outside the city,and the relationship between urban development and river waters becomes closer.However,the "unification" and "canal drying" of rivers in the process of urbanization make urban rivers gradually lose their diversity,and at the same time,threats and damages to urban environment are gradually revealed.How to continue the original landscape style of the river,and let the city and the river together,make it into the city of nature,is worth our attention to study the problem.From the perspective of landscape architecture,this paper explores the design strategies of urban secondary rivers under the concept of near-nature.Urban rivers are given the role of connecting cities and nature,balancing the relationship between cities and nature,maintaining and restoring the natural landscape of rivers,and integrating them into the urban environment.Following the linear logic of "finding problems--focusing on problems--analyzing problems--solving problems",this paper studies the planning and design of secondary urban rivers.This paper is mainly divided into four parts:The first part includes the first and second chapters: firstly,the origin of the topic,research purpose and significance are elaborated,the research object of this paper is determined,the concept definition of secondary rivers and near-nature ideal is clarified,the development context of near-nature theory is sorted out,and the research framework is built.Then the natural structural characteristics of rivers are studied and analyzed,and the existing problems of urban rivers are put forward.Based on the above research,this paper summarizes the characteristics and current problems of secondary rivers in the main urban area of chongqing.The second part is the third chapter: the related basic theory and practice project is studied.The connotation of the theory of river near-nature chemistry and the concrete measures in practice are clarified.The third part is the fourth chapter: it summarizes the principles and treatment methods of secondary river landscape design under the concept of near nature.Based on the connotation and experience of the near nature thought,the design strategy of the secondary river landscape design in the near perspective is summarized,which provides the basis for the practical design of the project.The fourth part includes the fifth and sixth chapters: elaborate the overall planning layout and specific design strategy of the zhuxi river landscape,and test the design strategy of the river landscape from the near nature perspective;Finally,the main conclusions and shortcomings of this paper are summarized.
