Research On River Landscape Optimization Strategy Of Beijing Sanhuan Water System Based On Ecological Design Concept

In recent years,the optimization of river landscape has become the focus of research by experts and scholars at home and abroad.The disciplines involved in river landscapes are very complex.Compared with other types of landscape spaces,rivers as a specific landscape space have their unique ecological benefits and society.Value is also an ecologically sensitive area.The water system of the river is not only an important carrier of the ecological environment and natural resources,but also plays a vital role in today’s social development.This paper takes Beijing Sanhuan water system as the research object,and studies its river landscape optimization strategy based on the ecological design concept.Under the background of Beijing’s social development,it interprets the corresponding norms and national policies,and analyzes the current Beijing Sanhuan Water System.The problems existing in the river channel are combined with the relatively mature ecological design theory at home and abroad to learn from and analyze the dynamics of river landscape optimization under the international environment.Based on the ecological design concept,the corresponding optimization strategies for the water source and landscape problems of the Beijing Sanhuan water system are proposed.Through the data collection and corresponding literature analysis,the concept of river landscape is defined,combined with the basic conditions of the river landscape,the three elements of the design,the design principles and the ecological design concept.The analytic hierarchy process is used to analyze the river landscape optimization strategy of the Beijing Sanhuan water system.s.The analysis system is mainly constructed for five optimization aspects of river landscape,including river channel form,river section design,ecological bank design,plant community construction and regional cultural integration.The river channel landscape optimization strategy analysis system is compared through expert questionnaires.Corresponding analysis results.Through on-the-spot investigation and data collection,the spatial pattern of the main river channel landscape of the Beijing Sanhuan Water System was initially mastered,and the general situation of the Beijing water system was analyzed.The water resources related problems of the Beijing Sanhuan water system were proposed,and the main river channel landscape space of the Sanhuan water system was proposed.The problem is analyzed,and the specific optimization strategy is studied by the weight result obtained by the analytic hierarchy process.According to the specific functions of the first ring system river channel,the second ring water system channel and the third ring water system channel in the three-ring water system channel According to the current situation of landscape space,different optimization strategies are proposed,and the water resources optimization strategy and landscape optimization strategy of Beijing Sanhuan water system based on ecological design concept are derived,and the corresponding optimization mode is proposed.
