Study On The Planning Strategy Of Xi'An Rural Road Ecological Landscape Based On Low Impact Development Concept

"If you want to be rich,build roads first",as the main channel for human activities such as production and life,road construction plays a very important role in promoting regional socioeconomic and cultural development.In the process of planning and construction of road space system,which is the spatial connection of rural human settlements environment,most of the previous concerns focused on road accessibility,road engineering design and construction management,while the ecological and landscape aspects of village roads lacked the necessary attention.The formation of road network and road construction will change the original ecological landscape structure around.In the course of road operation,it will continue to cause damage and pollution to the surrounding areas to a certain extent.Therefore,it is of great practical significance to strengthen the ecological research of village road space and the ecological civilization construction of roads for creating beautiful countryside,creating good ecological environment,living environment and production environment.Based on the existing problems of ecological disturbance and landscape fragmentation in Village Road construction,this paper combs the relevant theories and practical studies of low impact development at home and abroad,and provides theoretical basis for the application of low impact development concept in China.This paper deeply analyses the connotation and characteristics of the concept of low-impact development,the coupling relationship between it and village roads,and puts forward the goal orientation of low-impact Road Development planning.Thirdly,the basic investigation of Xi'an's village roads is carried out.Under the background of Xi'an's village roads construction,the feasibility,necessity and appropriate methods and measures of implementing the concept of low-impact development are the pedals.The reasonable combination of road system,rainwater system,green space system and low impact development concept is discussed.Through systematic research on the function,shape,grade and layout structure of village roads,low-impact development methods and strategies that best match the rural soil hydrological conditions in Xi'an were selected to generate road ecological landscape optimization path.And select Jixian Town,Zhouzhi County,Xi'an City,as a typical area across the Guanzhong Plain and the northern foot of Qinling Mountains,to make a comprehensive analysis,and use representative typical village cases to verify the feasibility of the strategy.The construction of village roads should start from five aspects: road ecological planning and design,landscape greening layout,environmental quality control,resource conservation and utilization,operation and maintenance management,so as to create a green,safe and comfortable village road with beautiful environment and excellent quality.Let its construction and development life cycle to minimize the impact of rural ecological environment.At the same time,it provides effective suggestions and references for the renewal and development of rural human settlements environment and the planning of village road landscape,so as to realize the complementarity of beautiful rural construction and high-quality road development in Xi'an.
