Research On Topography Design Of Xinhe River Corridor Based On River Geomorphology

The traditional river ecological restoration landscape design cannot create a river landscape type suitable for ecological restoration and urban development,and the river topography design from the perspective of landscape architecture is an important way to coordinate multi-disciplinary collaboration and intervene in river ecological restoration,and is based on "use practice" The "definition of research focus" idea,the research problem of this article is directly faced with the project practice,that is,the flood control project has serious interference with the geomorphology of the Xinhe River corridor,which corresponds to the content of geomorphological restoration in river ecological restoration.Based on the above research,the research question of this paper is put forward,that is,how to improve the spatial heterogeneity and connectivity of river geomorphology through the design of river flat and cross-sectional shapes,so as to alleviate the interference of flood control projects(negative)on river geomorphology and give full play to it.Comprehensive effectiveness of river ecosystem services?In view of the above research issues,this paper starts from the perspective of landscape architecture and uses the terrain design method in the landscape design approach to carry out the research on the diversity design of the Xinhe River landform morphology.1)Research on the influencing factors,laws and characteristics of the evolution of river geomorphology,to clarify its natural processes and natural forms,and use this as an important design basis and prototype for river terrain design based on river geomorphology.2)Construction of river topography design framework based on river geomorphology.Analyze the ecological problems of "interference caused by flood control projects on river geomorphology",put the ecological problems into the physical space level,study this from the three perspectives of macro,meso and micro,and finally get the coercion affecting the geomorphology of the river Factors;guided by the aforementioned stress factors,this paper studies the design methods of stress factors through case studies,literature and other research methods,and summarizes the river terrain design methods;in order to apply the first two results effectively and reasonably to specific In the river corridor space,the research proposes to control the design process,that is,the technical route of river corridor topography design.3)Following the research logic of the river topography design framework based on river geomorphology,taking Xinhe River as a specific practical object,applying this framework to the terrain design of Xinhe River,facing the ecological problems in design practice directly,and Take the opportunity to test,modify and enrich the framework.4)As a research on the promotion and application of the river topography design framework based on river geomorphology,the study aimed at the inadequacy of the existing design schemes,selected "river space" and "wildflower center section" as the optimal design objects,and used the framework for different goal-oriented Multi-program simulation and comparative research,better exploration of its attempted design practice,and the opportunity to further identify the scope and characteristics of each design method.In summary,this article can draw the following conclusions:1)Problem-oriented,this paper summarizes and summarizes the channel topography design framework based on river geomorphology through cases and literature research,which mainly includes stress factor analysis,channel topography design methods and channel topography design techniques that affect the channel topography The three parts of the route can supplement this subject's research focus on mitigating flood control engineering design(passive)interference with river geomorphology.2)Taking Xinhe River as the design practice object,according to its existing ecological problems,the design framework constructed in the early stage is applied to the terrain design of Xinhe River.Studies have shown that the framework can be applied to specific design practice projects,and as a coping method to solve the ecological problems of the Xinhe River,it can better improve the spatial heterogeneity and connectivity of river geomorphology,and better Mobilize the comprehensive effectiveness of its ecosystem services.3)Through the research on the new river topography design,this paper conducts research on the shortcomings of the existing river topography design method and finally obtains a revised and enriched river topography design method:the "habitat bank slope protection design" is in the existing nature On the basis of the protection of the type of bank slope,a new method is deduced in response to its shortcomings;and the terrain design method proposed for the special stress factor of the Xinhe River corridor is a supplement to the existing design method.4)In view of the shortcomings of the existing design schemes,the study obtained a better design scheme for optimizing the design objects through comparison of multiple schemes,and the study shows that the river basin topography design framework based on river geomorphology summarized in this paper can meet the different goal-oriented rivers.The space design requirements and the different prospects for the future development of the river space presented can provide a variety of design ideas and references for the improvement and optimization of the ecological restoration landscape of the Xinhe River in the future.
